Description

Dedicated fertilizer for meeting next batch of soybean

Technical field

The present invention relates to a kind of composite fertilizer, specifically relate to a kind of soybean continuous cropping plantation of being used for, especially the dedicated fertilizer for meeting next batch of soybean of control soy bean cyst roundworm and fungi infringement at continuous cropping and when meeting the stubble plantation.

Background technology

Soybean cyst nematode (English name: Heterodera glycines) be a kind of destructive disease on world soybean is produced, mainly be distributed in Japan, Korea, Egypt, the U.S., Brazil, and areas such as China northeast, the Yellow River and Huai He River sea; Be example with 1992 only, because of the direct economic loss that this disease causes, the U.S. is 1.2 hundred million dollars, and China is 4.0 hundred million Renminbi.Particularly the same continuous manufacturing soybean in ground, plantation in promptly 1 year claims " secondary soybean ", cyst roundworm harm was serious when plantation claimed " meeting a batch soybean " in the 3rd year, the flavescence of the lighter's soybean plant strain blade, weight person destroys soybean root system, growing of retardance soybean, simultaneously because the intrusion of cyst roundworm causes the increase of soybean root system openness, and then make as damping-off, the reaping hook root rot, one class fungal disease such as phytophthora root rot and anthrax increases the weight of, directly cause the underproduction of soybean, weight person causes plant death, total crop failure, total crop failure, the peasant is generally called above-mentioned illness in " flue seedling sprout ".

For preventing the infringement of soy bean cyst roundworm and fungi, the effective measure that adopt are crop rotations usually, apply the highly toxic pesticide control simultaneously; Except that with the fertile control of the medicine that contains highly toxic pesticide, recent, people are inquiring into technology prevention soybean cyst nematodes such as using chitinase technology, genetically engineered soybean.But because land area is limited, the rotation of crops is restricted; When using highly toxic pesticide or containing the medicated fertilizer of highly toxic pesticide, when killing soy bean cyst roundworm and fungi, unavoidably there is pesticide residue to exist in soil and the soybean, very unfavorable behind edible this agricultural products to human body; Chitinase technology still prematurity haves much room for improvement, and genetically engineered soybean food safety people still have doubt.China becomes soybean importer by soybean export State, and the harm that soybean cyst nematode causes can't but be one of one of them important factor.Therefore, can prevent and treat the infringement of soy bean cyst roundworm and fungi with fertilizer without agricultural chemicals is that people thirst for the technical problem that solves always.

Though domestic various crops general " second crop fertilizer " have appearred, in these fertilizer because micronutrient element is without handling such as chelating one class, poor activity, after using often fertilizer damage greater than fertilizer efficiency; Though have through chelation treatment, because of the sequestrant of selecting for use improper, or because of various nutrients cooperate ratios improper, cause preventing and treating soy bean cyst roundworm and fungi infringement, increase soybean yields or improve soybean quality effect undesirable.

Name is called the ZL90106014.3 patent of invention of " vigor element ", and wherein " the vigor element " of Pi Luing has promoter action to plant growth, but can not effectively control soy bean cyst roundworm.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of contain behind plant nutrient, the chelating in, trace element make in, trace mineral supplement fertilizer, be characterized in the purpose that combines achieve effective control soy bean cyst roundworm and fungi infringement with the non-nutrient effect and the trophism of plant nutrient without agricultural chemicals; Simultaneously with in the non-nutrient of plant nutrient and the patent of invention vigor element, the micro-element nutrition effect use that combines, reach the control soy bean cyst roundworm.

Realize that the technical scheme that the object of the invention adopted is:

A kind of dedicated fertilizer for meeting next batch of soybean, this fertilizer contain the nitrogen in nitrogen in the plant nutrient; With P ₂O ₅The phosphorus of meter; With K ₂The potassium of O meter; In behind the chelating, trace mineral supplement T, in the proportioning of weight part be:

N∶P ₂O ₅∶K ₂O∶T＝1∶2∶0～5.0∶0.429≥T＞0.0

The invention provides a kind of purposes of dedicated fertilizer for meeting next batch of soybean, described purposes is for being used to control soy bean cyst roundworm.

Beneficial effect of the present invention is: the present invention provides a kind of safety non-toxic for agricultural but fertilizer with agricultural chemicals function, started application composite fertilizer control soybean continuous cropping obstacle---the precedent of soil-borne disease, control the infringement of soy bean cyst roundworm and fungi thereof effectively, using back soybean flue seedling sprout sickness rate significantly descends, this fertilizer can make the soy bean cyst roundworm rate of going down reach more than 89.5%, and the field sickness rate drops to below 10% by 98%;

It is remarkable to use this fertilizer soybean yield-increasing effect: use 1～9 times of fertile contrast of the comparable nothing of this fertilizer or local habits fertilization (executing phosphorus two ammoniums and urea) volume increase when serious morbidity; At slight sickness rate with when not falling ill, increase production 2%～16%;

Use this fertilizer and can obviously improve soybean quality: soybean varieties is opened 8157 say, compare with habits fertilization, significantly improve the quality of soybean, make the crude fat content of some soybean bring up to 23%, and protein content does not fall, the two-phase sum is greater than 62%;

Simultaneously, behind this incorporation of fertilizerin the soil, soil and soybean there are not the residual of agricultural chemicals and pollution; And after this season fertilising, the plant nutrient that soybean does not absorb fully, part residues in the soil, can not produce harmful effect, can play the effect of culture fertility again.Simultaneously, this fertilizer can be made general soybean fertilizer and use on the plot that soybean cyst nematode does not take place,

Embodiment

Below in conjunction with embodiment the present invention is described in further detail:

A kind of dedicated fertilizer for meeting next batch of soybean, this fertilizer contain the nitrogen in nitrogen in the plant nutrient; With P ₂O ₅The phosphorus of meter; With K ₂The potassium of O meter; In behind the chelating, trace mineral supplement T, in the proportioning of weight part be:

N∶P ₂O ₅∶K ₂O∶T＝1∶2∶0～5.0∶0.429≥T＞0.0

In behind the described chelating, trace mineral supplement T for a kind of sequestrant of from HEDTA, DTPA, CDTA, TEA, NTA, EGTA, selecting with in, trace element chelated back forms.

In described, trace element is from Mg, Ca, SO ₄ ^-2, Na, Mn, B, Zn, Fe, Cu, Mo, Cl ^-1In select one or more.

In described, trace element is respectively from following respective compound and obtains:

MgSO ₄.7H ₂O；(NH ₄) ₆MO ₇O ₂₄.4H ₂O；CuSO ₄.5H ₂O；ZnSO ₄.7H ₂O；EDTA-Fe；

MnSO ₄.5H ₂O；Na ₂B ₄O ₇.10H ₂O；K ₂SO ₄；KH ₂PO ₄；NaHCO ₃。

Described fertilizer contains molybdenum.

Described fertilizer contains chlorine and/or sodium.

Dedicated fertilizer for meeting next batch of soybean of the present invention, this fertilizer is by the nitrogen that contains the macroelement in the plant nutrient (N), phosphorus (P2O5), in behind Potassium (K2O) and the chelating, the additive that trace element is made (T) carries out making after the proportioning, in order to suppress the infringement of soy bean cyst roundworm and fungi, must use excessive nitrogen N, phosphorus P2O5, potassium K2O, because the present invention uses excessive nitrogen, phosphorus, potassium, the nitrogen that these are excessive, phosphorus, potassium is to micronutrient element generation antagonism in soil or the plant, must be with in the metallic state of sequestrant with plant nutrient, trace element chelated, join in the plant again, in the micronutrient element, to solve the antagonism problem.As: potassium, boron, iron, zinc, copper, calcium, magnesium, manganese add nitrogen, phosphorus, potassium;

The preferred technical solution of the present invention is: if leguminous plants also must add molybdenum;

Another optimal technical scheme of the present invention is: if also need to mend chlorine in well-drained hilly country, 16 kinds of nutritive elements of Ren Dinging must be filled 13 kinds so in the world, wherein also must add beneficial element sodium Na ₂O is to assist the infringement of control sporangiocyst line nematode and fungi.

In behind the chelating, the selection principle of micro-used sequestrant is: because of the edaphic condition difference is selected different sequestrants for use, as: when the soil exchange acidity pH 〉=7.0, select sequestrant EDDHA for use; When soil exchange acidity pH≤7.0, can select for use the sequestrant such as a kind of among HEDTA, DTPA, CDTA, TEA, NTA, the EGTA all can.

When poor≤1 of soil exchange acidity and active acidity or≤0.4 the time, please refer to " micronutrient element one book in the agricultural ", must apply middle micronutrient element through chelating, otherwise, can't resolve the mutual antagonistic action between nutrient element.

As soil pH under alkali calcareous soil condition more than 8., can select for use quadrol two (O-hydroxyl phenylacetic acid) sequestrant (being called for short EDDHA) with in the metallic state, trace element chelated, again it is mixed into additive T.Form additive T in, trace metal attitude element press the oxide form composition, its component and content are:

MgO：8％~15％；CaO：8％~15％；SO ₄ ^-2：8％~15％；

Na ₂O：5％~10％；MnO：7％~10％；B ₂O ₃：4％~10％；

ZnO：5％~10％；FeO：5％~10％；CuO：2％~5％；

Mo ₂O ₃: 0.5% ~ 1%; Cl ^-1: 4% ~ 10%; Surplus is a sequestrant.

Definite principle of the proportioning between sequestrant and the metal nutritive element is: at first measure sequestrant functional group metal nutrient ionic saturated extent of adsorption (is used M ^xExpression: wherein M represents the metallic state plant nutrient, and the x in its upper right corner represents this nutritive element ion valence mumber); Thereby calculate the metal ion (M that is added ^x) and the sequestrant add-on, this has just determined the consumption of a certain metallic state nutritive element and sequestrant; The ratio of these two amounts is exactly this nutritive element and the ratio that cooperates of sequestrant.To determine one by one each metallic state nutritive element.At present, we buy micronutrient element in the metallic state behind the chelating at home and abroad on the market easily, as:

EDDHA-Mg, EDDHA-Mn, EDDHA-Ga, EDDHA-Zn, EDDHA-Fe, EDDHA-Cu, EDDHA-Mo etc.

In the heavy metal among the dedicated fertilizer for meeting next batch of soybean additive T of the present invention, after the micronutrient element process chelation treatment, nutritive element is activated, can be implemented on the production of compound fertilizer line or meet phosphoric acid salt in the soil and not precipitate, thereby keep these nutritive element nutrient availabilities.

Under the condition that antagonistic action must take place, the luffing of its component and content be chosen as (additive for preparing is represented with T) as:

MgO：13％；CaO：10％；SO ₄ ^-2：14％；Na ₂O：8％；MnO：9％；

B ₂O ₃：6％；ZnO：10％；FeO：10％；CuO：3％；Mo ₂O ₃：1％；Cl ^-1：10％

In additive, require minimum plant nutritive element available nutrient to account for additive total amount 〉=20%.

In behind the described chelating, the additive T that makes of trace element can be that patent of invention number is: ZL90106014.3, name are called: the vigor element, its composition is:

MgSO ₄.7H ₂O：30％；(NH ₄) ₆MO ₇O ₂₄.4H ₂O：1％；CuSO ₄.5H ₂O：2％；

ZnSO ₄.7H ₂O：4％；EDTA-Fe：6％；MnSO ₄.5H ₂O：17％；Na ₂B ₄O ₇.10H ₂O：10％；

K ₂SO ₄：12％；KH ₂PO ₄：7％；NaHCO ₃：8％；C ₆H ₈O ₇H ₂O：1％；C ₁₂H ₂₂O ₁₁：2％。

The T that said components is formed makes the present invention according to the proportioning in the claim 1.

Minimum plant nutritive element additive T cooperates with a large amount of nitrogen, phosphorus, potassium respectively, and the cooperation ratio should be carried out national standard GB15063-2001.

Dedicated fertilizer for meeting next batch of soybean of the present invention, when specifically implementing, nitrogen (N), phosphorus (P ₂O ₅), Potassium (K ₂O) can suit measures to local conditions (the soil testing and fertilizer recommendation principle of using by China Ministry of Agriculture rational application of fertilizers principle or Global Access) select ammonium chloride or urea, calcium superphosphate or phosphorus two ammoniums, Repone K or vitriolate of tartar for use.Table 1 is the formula rate and the plant protection effect abridged table thereof of environmental protecting fertilizer specially for ratooning soybeam

Annotate: embodiment 1-6 set of dispense is than identical in the prescription 1-6 in the table 5 and the above-mentioned table 4.

The result of Ulan Hot (test 1) shows (seeing Table 5): use the processing of soybean fertilizer and compare with the contrast of not applying fertilizer, breeding time is 3 days maturations in advance, and its 100-grain weight, plant height, grain yield all have tangible increase effect.Two ammoniums, fertile 1 big dragon of medicine, medicine fertilizer 2, prescription 1, prescription 2, prescription 3, prescription 4, prescription 5, prescription 6 do not increase production 4%, 543%, 700%, 594%, 628%, 940%, 858%, 152% and 833% respectively than there being fertile contrast, compare with medicine fertilizer 2, prescription 3,4,6 has certain effect of increasing production; Compare with fertile 1 big dragon of medicine, except that prescription 5, other prescriptions have tangible effect of increasing production, and fill a prescription and 3,4,6 reached the conspicuous level on the statistics, and effect of increasing production is very obvious.

The result in Gongzhuling, Jilin (test 2) shows (seeing Table 5), and two ammoniums, fertile 1 big dragon of medicine, medicine fertilizer 2, prescription 1, prescription 2, prescription 3, prescription 4, prescription 6 do not increase production 0.6%, 6.3%, 15.9%, 15.8%, 14.3%, 12.6%, 11.5%, 2.3% respectively than there being fertile contrast.Find that in species test result's investigation prescription 1 is all best at plant height, 100-grain weight, in full accord with the output performance.The volume increase value of having only prescription 1 not have fertile contrast, traditional fertilization two ammoniums has reached conspicuous level, though the output of prescription 2,3,4,6 is better than contrast, two ammoniums, medicine fertile 2 or fertile 1 big dragon (containing highly toxic pesticide) of medicine, does not reach the conspicuous level on the statistics.Model field 1 test-results prescription 1 is better than fertile 1 big dragon of medicine, medicine fertilizer 2, phosphorus two ammoniums and contrast, compare effect of increasing production with phosphorus two ammoniums with contrast and all reach conspicuous level on the statistics, and model field 2,2 soybean yieldss of filling a prescription also are higher than fertile 1 big dragon of medicine, medicine fertilizer 2, phosphorus two ammoniums and contrast, but have only reached conspicuous level (data are unlisted) compared with the control.

Changtu, Liaoning (test 3) two ammoniums, fertile 1 big dragon of medicine, medicine fertilizer 2, prescription 1, prescription 2, prescription 3, prescription 4, prescription 5, prescription 6 do not increase production 79%, 111%, 156%, 159%, 176%, 179%, 159%, 148%, 198% respectively than there being fertile contrast.The output of 6 prescriptions is significantly higher than fertile 1 big dragon (containing highly toxic pesticide) of contrast, phosphorus two ammoniums and medicine, and the output and the species test factor of prescription 6 all behave oneself best, and output is higher than medicine fertilizer 2.

But 6 prescriptions have certain difference in above three geographic performances, in Gongzhuling, Jilin, the prescription that behaves oneself best of Changtu, Liaoning, Ulan Hot, Inner Mongol is respectively: prescription 1, prescription 6, prescription 3, this has reflected that this fertilizer and basic fertility of test soil have bigger relation.The Inner Mongol experimental field, the sickness rate of cyst roundworm is the heaviest, prescription 3 soybean yields is higher, illustrates that the ratio of nitrogen, phosphorus, potassium is suitable with 1: 2: 2.Lighter relatively in Gongzhuling, Jilin cyst roundworm morbidity, but the content of rapid available phosphorus is relatively low, prescription 1 (N: P: K is 1: 2: 3) is the highest in go down rate and the soybean yields performance of the plant height of investigation in mid-term and cyst roundworm.Occurring degree at Changtu, Liaoning cyst roundworm is medium, and rapid available phosphorus lacks very much.Content only is 11.0mg/kg, the content of nitrogen, potassium is higher relatively, the higher relatively phosphorus of prescription 6 (N: P: K is 1: 2: 1) has replenished the situation that phosphorus lacks in the soil, get in touch with the analytical data of table 2 and analyze to find, obtained the performance of consistent the best in go down rate, soybean strain weight in average and soybean kernel output of cyst roundworm.

6) the dedicated fertilizer for meeting next batch of soybean material is to the influence of soybean crude fat and crude protein content

As shown in Table 6, three crude protein and content of crude fat experimental field have certain difference, crude protein＞Gongzhuling, Jilin＞Changtu, Liaoning experimental field, Ulan Hot, Inner Mongol, but crude fat is just in time opposite.Analyze from the crude protein percentage composition, the environmental protecting fertilizer specially for ratooning soybeam material is not higher than other to be handled, and is certain opposite tendency with the output of soybean, and contrast, two ammoniums, fertile 1 big dragon of medicine, filling a prescription 5 has shown certain advantage aspect crude protein.The gross production of environmental protecting fertilizer specially for ratooning soybeam material per hectare crude protein and crude fat has remarkable advantages.The crude fat content analysis as can be known, being applied in when improving output of environmental protecting fertilizer specially for ratooning soybeam material formula, also improved content of crude fat in the soybean kernel, but three content experimental field have certain difference, and the amplitude that the crude fat content of environmental protecting fertilizer specially for ratooning soybeam improves compared with the control is 0.2%-2%; Compare with traditional fertilization, crude fat content improves 0.5%-3.36%; The increasing degree of comparing the soybean crude fat content with medicine fertilizer is 0.8%-1.8%, and the crude fat content of the land area of one unit of environmental protecting fertilizer specially for ratooning soybeam material is far longer than fertile 1 big dragon (containing highly toxic pesticide) of medicine and the medicine fertilizer 2 that contrast, traditional fertilization, custom are used.In addition, as can be seen from Table 5, the environmental protecting fertilizer specially for ratooning soybeam material is when improving soybean yields and crude fat content, and the crude fat of part prescription and crude protein content sum are greater than 62%, and this is the important factor of constant soybean quality.

Four. brief summary

All can obviously suppress the symptom of soybean flue seedling sprout at cyst roundworm serious Ulan Hot 6 prescriptions of test dedicated fertilizer for meeting next batch of soybean material of falling ill; Light and moderate experimental field though do not show the flue seedling sprout, passes through that mid-term, the survey showed that in cyst roundworm morbidity, and the using of this fertilizer can obviously be improved the soy bean cyst roundworm rate that goes down.

Three the test site test-results different in soybean continuous cropping obstacle degree show: the environmental protecting fertilizer specially for ratooning soybeam material all has certain production-increasing function to the output of soybean, but amount of increase in production has evident difference.Production-increasing function highly significant in the serious Ulan Hot, Inner Mongol of morbidity, with contrast, traditional fertilization is compared, except that prescription 5, other prescriptions have all reached significantly and extremely significant level, in lighter Changtu, Liaoning and the Gongzhuling, Jilin of morbidity production-increasing function is preferably arranged also, the production-increasing function of part prescription has also reached the conspicuous level on the statistics, as seen this fertilizer has the effect of two aspects, one can alleviate the symptom of the continuous cropping obstacle of serious soybean, remarkable production-increasing function is arranged, its two, can be used as the soybean continuous cropping obstacle gentlier or the soybean fertilizer on the soil of not falling ill, tangible production-increasing function is arranged equally.

Dedicated fertilizer for meeting next batch of soybean has certain increase effect to content of crude fat in the soybean kernel, thereby has increased the gross production of crude protein and crude fat greatly.In a word, utilize the nutrient of plant nutrient and the dedicated fertilizer for meeting next batch of soybean material of non-nutrient effect development in the continuous cropping obstacle that solves soybean, to obtain progress preferably, solve the soil-borne disease problem for solving without agricultural chemicals, certain basis has been established in the production of exploitation green food.
