Description
Technical field
The invention belongs to the chemical fertilizer field, be specifically related to a kind of nano biological organic and inorganic composite fertilizer.
Background technology
The fertilizer of using on the agricultural is divided into microbial fertilizer, organic fertilizer and chemical fertilizer three major types.Wherein microbial fertilizer has following characteristics: (1) belongs to a kind of indirect fertilizer, and itself does not contain nutritive element, but by its vital movement, the nitrogen in the fixed air, the insoluble phosphorus of decomposition soil, potassium element are made for thing and absorb; (2) assist the crop overall balance to absorb nutrient, improve plant recovery of nutrient; (3) affine with plant height.But the performance of microorganism effect depends on that (at present mu is used and mostly is about 1kg for its quantity, seed soaking or be stained with root), with the competitive power of indigenous bacterium and the height of soil organic matter content, these factors make the microbial fertilizer fertilizer efficiency stable inadequately, influence its further popularization.Organic fertilizer contains the required multiple nutrient of crop, can make crop quality improvement, soil fertility keep balance, soil fertility Chang Xin; But the content of available nutrient is less in the fertilizer, and amount of application is bigger.Chemical fertilizer contains abundant quick-acting nitrogen, phosphorus, potassium element, and obvious effect of increasing production, but long-term single administration chemical fertilizer make soil compaction, and soil fertility descends, and crop quality reduces, contaminate environment.
Mixed organic fertilizer is to utilize modern comprehensive microbial technique, fertilizer and microorganism fertilizer, and inorganic N, P, K fertilizer, science bonded products such as little fertilizer, be the novel compound fertilizer of a kind of pleiotropy, it is comprehensive to have a nutrient, long-acting and quick-acting combining, improve utilization rate of fertilizer, improve Soil structure and Li Fu, reconcile microbial environment, the effect that increases fertility of land obviously waits effect, and becoming one of new-type fertilizer that plant husbandry uses, particularly cash crop, to execute network increasing.
Although organic-inorganic compound fertilizer has above-mentioned advantage, but its utilization ratio is lower, not only cause the huge waste of resource, also caused the serious environmental pollution, the problems such as content severe overweight of nitrogen in face of land eutrophication, underground water and the vegetables appear in some area.In addition, near the fertilizer of the overconcentration of power in the managerial system crop also may burn out the root system of crop.Because the existence of the problems referred to above, usually in the whole growth process of crop, must carry out an amount of several times fertilising, to satisfy crop growth period to nutrient demand, not only lavish labor on yet repeat fertilising, fertilizing equipment also may bring certain outer damage to crop.Therefore, improve utilization rate of fertilizer, alleviate its pollution, develop sustainable high-efficiency agriculture and become the common problem of paying close attention in various countries environment.
And nano fertilizer can improve the utilising efficiency of fertilizer and reduce its negative impact to environment, is not subjected to the influence of complicated factors such as soil type, can significantly reduce soil and phreatic pollution, greatly improves output.And nano fertilizer is compared common chemical fertilizer, and effect of increasing production is fine, can strengthen the resistance of crop, and quality can compare favourably with applications of farmyard manure, and the ideal that is the pollution-free vegetable cultivation is with fertile.Therefore, produce the nano grade biological composite organic-inorganic fertilizer, become an important directions of current agricultural fertilizer development.
In China, the main raw material of soy sauce is dregs of beans and flour, produces the waste residue times over raw material after fermentation, oil pumping, i.e. the soy sauce slag.The soy sauce waste residue by analysis, remaining rich nutrient contents, see the following form:
Dried soy sauce dreg chemistry composition g/100g
| Moisture | Crude protein | Crude fat | Reducing sugar | Salinity | Calcium | Phosphorus | Robust fibre | Ash content |
| 8.0- 9.0 | 19.5-2 5.8 | 7.4-8. 6 | 10.7-12. 3 | 0.5-2. 0 | 0.1 | 0.67 | 38 | 8.40 |
What local peasant had directly goes to the field it, and fertilizer is worked as in have its stacking is gone to the field after spontaneous fermentation again.But above-mentioned way all can influence crop growth, and makes soil compaction, simultaneously polluted air and water source, and the existence that jeopardizes hydrocoles has again damaged resident's health.Up to the present, utilize microbial strains to make behind the soy sauce residue fermentation and mineral manure is made Nano type high-performance bio composite organic-inorganic fertilizer after composite and still is not reported.
Summary of the invention
The present invention provides a kind of Nano type biologic organic, inorganic composite fertilizer for the environmental pollution that solves soy sauce slag waste and cause and the low problem of utilization ratio of compoiste fertilizer at present, and it adopts modern nano junction configuration biotechnical processes and prescription, the fertilizer product of making is nontoxic, nuisanceless, and have fertile multi-functional characteristics, tangible adjusting plant internal hormone balance is arranged, the control plant growth coordinating, improve the soil, disease-resistant antibiotic, increase operation rate, improve output, improve effects such as crop quality.

| Celery | 2206 | 3571 | 4355 | 4356 | 4351 |
As can be seen from Table 2, with the comparison of not applying fertilizer, these crops are all increased production.And use the Nano type biologic organic, inorganic composite fertilizer, several crops all there is quite significant effect of increasing production.
Embodiment 6
Influence to Tomato Quality
The method fertilising identical with embodiment 8 detects its quality after waiting the tomato maturation, the results are shown in Table 3.
Table 3: different fertilizer is to the influence of Tomato Quality
| Index | Do not apply fertilizer | Deng the nutrient chemical fertilizer | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Nitrate nitrogen content (mg/kg) | 12.25 | 180 | 122 | 125 | 130 |
| VC content (mg/kg) | 10 | 11 | 13.2 | 13.1 | 12.8 |
| Total sugar content (mg/kg) | 3.42 | 3.42 | 4.4 | 4.5 | 4.36 |

| Sugar/sour ratio | 13.15 | 14.25 | 16.03 | 16.07 | 16.05 |
As can be seen from Table 3, compare with not applying fertilizer, use biological organic complex fertilizer and the Nano type biologic organic, inorganic composite fertilizer improves significantly to the Tomato Quality tool with chemical fertilizer.Nitric nitrogen, Vc, total reducing sugar amount, total acid content and sugar-acid ratio content obviously improve in the fruit, and the more remarkable effect of Nano type biologic organic, inorganic composite fertilizer.
Embodiment 7
Influence to heavy metal content in the tamato fruit
The method fertilising identical with embodiment 8 detects its heavy metal content after waiting the tomato maturation, and the result shows: compare with not applying fertilizer with chemical fertilizer, obviously reduced the content of Hg, Pb in the tomato after using biologic organic, inorganic composite fertilizer and Nano type biological organic complex fertilizer.
Embodiment 8
The toxicity test result
In the acute toxicity test of rat oral, this fertilizer of 7500mg/kg does not cause rats death, does not have acute toxic action.The no abnormal performance of duration of test animal, body temperature is normal, cuts open inspection and does not see that obvious pathological change takes place each internal organs, illustrates that this fertilizer does not have obvious pathogenic effects.Carry out the karyomit(e) mutagenesis testing with fertilizer leach liquor abdominal injection of the present invention, mouse marrow polychromatophilia micronucleus in erythrocytes rate and chromosome aberrations rate do not have remarkable rising, show fertilizer dye-free body mutagenesis of the present invention.
