Description
Technical field
The present invention relates to fertilizer preparing technical field, and in particular to a kind of cucumber Special slow release fertilizer of raising element utilization rate
And preparation method thereof.
Background technology
Cucumber Curcurbitaceae is annual to overgrow or climbs up by holding on to herbaceous plant.Stem, branch elongation, have rib ditch, by the rough bristle of white.Volume
Must be thin.Petiole is slightly coarse, there is rough bristle；Blade ovate wide is heart-shaped, and film quality, sliver triangle is with teeth.Monoecism, cucumber flavor
It is sweet, it is sweet, cool in nature, bitter, nontoxic, enter spleen, stomach, large intestine；With except heat, sharp water diuresis, clearing heat and detoxicating effect；Polydipsia is cured mainly, is swallowed
Larynx swells and ache, pinkeye, burning hot wound.Also effect of weight reducing, cucumber rich in protein, carbohydrate, vitamin B2, vitamin C, vitamin E,
The nutritional ingredients such as carrotene, niacin, calcium, phosphorus, iron.
Because cucumber has high edibility and nutritive value, therefore the cultivation technique of cucumber just occurs in succession, yellow
The control of fertilizer is particularly critical in melon cultivation, because cucumber cultivation is in soil, after fertilizer is applied for a period of time, except
Sub-fraction can absorb outer by cucumber, other then can be lost in, and cause substantial amounts of waste, but also can cause the pollution of soil,
With going deep into for Research of Environmental Sciences, people gradually recognize contamination hazard of the heavy metal to soil be it is extremely serious, in order to
Reduce this loss, must be requested that the release rule of the nutrient of fertilizer is coordinated with the Nutrient Absorption of cucumber, therefore Controlled Release Fertilizer grinds
System becomes more and more.With going deep into for Research of Environmental Sciences, people gradually recognize heavy metal-polluted soil heavy metal in soil
Existing forms can be divided into：Exchangeable species；Carbonate combine state；Iron and manganese oxides combination state；Sulfide and organically combine state；Residue
State etc..Exchangeable species belong to effective and are easily absorbed by crops utilization, referred to as using state；Carbonate combine state refers to and carbon
The heavy metal that hydrochlorate is combined；Ferrimanganic combination state refers to the heavy metal ion combined with ferrimanganic, there is very strong combination energy between them
Power；Sulfide and organically combine state refer to the heavy metal combined with sulphur and the heavy metal ion that complex compound is formed with organic matter；It is residual
Slag state refers to the heavy metal ion extracted and existed with phyllosilicate form after aforementioned four component, wherein exchangeable species and is had
The biological effectiveness of machine combination state heavy metal is higher, and other biological effectivenesses are low.Therefore exchangeable species how to be reduced and is had
The biological effectiveness of machine combination state heavy metal is the key point for processing the heavy metal in soil, existing treatment heavy metal in soil
Method mainly have：The methods such as curing/stabilizing, chemical reagent extraction, microorganism leaching, burning, phytoremediation.Chemical method,
The shortcoming of bioanalysis, phytoremediation and burning method is：Removing heavy metals are removed from soil not only needs substantial amounts of financial resources, thing
Power, and take this method clearly unpractiaca in face of soil, and those absorptions are enriched the plant of heavy metal, there is also
And be difficult to further treatment, and be likely to result in secondary pollution problem.It is this present inventor by substantial amounts of experiment and research, carries
Having supplied one kind can not only provide nutrition to cucumber growth, moreover it is possible to effectively solve nutrient element loss, heavy metal pollution of soil has
Cucumber Special slow release fertilizer of raising element utilization rate of malicious harmful substance pollution and preparation method thereof.

Improve the preparation method of the cucumber Special slow release fertilizer of element utilization rate：By potassium sulfate, ammonium sulfate, urea, peroxophosphoric acid
Granulation obtains particle diameter for 2-5mm, N after calcium, potassium dihydrogen phosphate, additive, reaction promoter are well mixed：P2O5：The mol ratio of K2O
It is 2:3:1 composite fertilizer, then the composite fertilizer is obtained into compound with modified montmorillonite used being well mixed, using by PLA, poly- second
The degradation material obtained after alkene blending is 1.2 according to mass ratio with compound：1 ratio is wrapped up is improved element
The cucumber Special slow release fertilizer of utilization rate.
With reference to specific experiment example, the present invention is described further：
Experimental example 1
This slow-release fertilizer field demonstration test, experimental field ground is in Guizhou, has a moderate climate, with heavy rainfall, using every mu of field
Label is tested, and 10 mu of fields, the slow-release fertilizer prepared using conventional fertilizer application and conventional fertilizer application+the present embodiment 1-9 are selected altogether
Cucumber cultivation experiment is carried out, experimental result is as shown in table 1：
The slow-release fertilizer field demonstration test of table 1
| Project | Theoretical per mu yield (kilogram) | Actual per mu yield (kilogram) |
| Conventional fertilizer application | 16000-20000 | 19356 |
| Conventional fertilizer application+embodiment one | 18000-26000 | 28136 |
| Conventional fertilizer application+embodiment two | 18000-26000 | 26893 |
| Conventional fertilizer application+embodiment three | 18000-26000 | 27489 |
| Conventional fertilizer application+example IV | 18000-26000 | 26893 |
| Conventional fertilizer application+embodiment five | 18000-26000 | 26703 |
| Conventional fertilizer application+embodiment six | 18000-26000 | 26690 |
| Conventional fertilizer application+embodiment seven | 18000-26000 | 27630 |
| Conventional fertilizer application+embodiment eight | 18000-26000 | 28331 |
| Conventional fertilizer application+embodiment nine | 18000-26000 | 27231 |
The plantation of cucumber its yield is carried out by the way of conventional fertilizer application as seen from the above in theoretical value, and uses normal
The rule slow-release fertilizers prepared of fertilising+the present embodiment 1-9 carry out the plantation of cucumber its yield and are not only above theoretical value but also much
It is using conventional fertilizer application higher than independent, therefore be that there is effect of increasing production higher using the plantation that the present invention carries out cucumber.
Experimental example 2
Heavy metal-polluted soil treatment experiment：
Surveyed as carrier addition exogenous heavy metal pollutant with the free of contamination cinnamon soil in Guizhou Province and contained at its soil depth 5-20cm
Pb100mg/kg, Cd6mg/kg, Cr900mg/kg, Cu980mg/kg, using the soil as experiment soil, by the embodiment of the present invention
During the slow-release fertilizer prepared delivers experiment soil, heavy metal concentration inspection at soil soil depth 5-20cm is carried out after 15 days
Survey, its testing result is as shown in table 2：
The heavy metal-polluted soil of table 2 processes experimental result
From the foregoing, it will be observed that being delivered in experiment soil after 15 days using the slow-release fertilizer prepared in the embodiment of the present invention, soil
Content of beary metal at 5-15cm is significantly reduced, and illustrates that the thio sulfide contained in this slow-release fertilizer occurs with heavy metal ion
Reaction production precipitation, so as to heavy metal ion be fixed, prevents it from passing through leaching and footpath stream migration, in addition in this slow-release fertilizer
Thio sulfide valence heavy metal ions can also be reduced into lower valency, effectively reduce its toxicity and dissolubility.
