Description
Technical field
The invention belongs to chemical fertilizer potentiating pink collar domain, and in particular to a kind of chemical fertilizer nutrient controlled release powder and its manufacture method.
Background technology
The Ministry of Agriculture in 2015 puts into effect file regulation and realized chemical fertilizer to the year two thousand twenty since 2015 while increases in grain production
Agricultural chemicals zero growth rate,<Global environment prospect five>Explicitly pointed out in threshold limit value：The freshwater lake system caused by eutrophication
System collapse.Atmosphere and water pollution deteriorates, and nitrogen of the water pollution in chemical fertilizer, phosphorus etc. enter water body and caused
Make body eutrophication, the most important inducement of atmosphere pollution is greenhouse gas emission.Due to a large amount of improper uses of chemical fertilizer, utilize
Rate is low, and China has 1,500,000 tons of nitrogen to flow to rivers and lakes by surface water footpath every year, and 600,000 tons of nitrogen enter underground water, 3,200,000 tons of nitrogen
Into air.The approach such as nitrogen runoff, elution enter water body, cause rivers and lakes eutrophication, volatile matter is with N2O forms enter big
Gas, greenhouse gases are caused to increase.It can be seen that a large amount of of chemical fertilizer are supported using the Tri-dimension Pollution for foring " from underground in the air ", chemical fertilizer
The loss divided is startling！
Because fertilizer does not control Chaohu total nitrogen total phosphorus severe overweight of one of loss scheme, five big fresh water lake of China effectively,
The content of the four section nitrate nitrogen in water bodies in Second Songhua River wet season downstream is above dry season and the period when a river is at its normal level, and Kunming Dianchi lake is big
Measure green alga to produce, Yangtze river basin body eutrophication.This is all that the nitrogen phosphorus that riverine, lake two sides paddy field, dry land are applied moves with water body
Caused by shifting.The nitrogen in nitrogen and application fertilizer in soil is in the presence of rainfall and irrigation water, and part is directly with the shape of compound
Soil lower floor is arrived in formula elution, most of finally to be eluted in the form of the nitrate nitrogen, nitrite nitrogen and ammonium nitrogen of solubility under soil
Layer.
It can be seen that it is to reduce water pollution that control chemical fertilizer nutrient, which is lost in, the matter of utmost importance of utilization rate of fertilizer, existing chemical fertilizer are improved
Nutrient controlled release agent using attapulgite magnetization treatment because bringing cost to remain high so that control is lost promoting the use for fertilizer and limited
System, so developing a kind of low-cost environment-friendly chemical fertilizer nutrient controlled release powder seems particularly significant.
The content of the invention
Ask the invention aims to the N P and K composition for overcoming chemical fertilizer in the prior art is easy to run off, utilization rate is low
Topic, there is provided a kind of chemical fertilizer nutrient controlled release powder and its manufacture method.The high-molecule chelated accelerator poly-aspartic potassium of present invention utilization,
Macromolecule composite surface conditioner polyacrylic acid potassium, macromolecule composite surface conditioner xanthans, the conditioning of macromolecule composite surface
Agent methylcellulose, macromolecule composite surface conditioner Acritamer 940, chitosan, bentonite water conservation and microgrid shape knot
Structure, chemical fertilizer nutrient controlled release powder is made in warm activation process again after being sufficiently mixed, after adding chemical fertilizer nutrient controlled release powder in fertilizer,
It can reduce nitrogen, phosphorus element, potassium by nitrogen, phosphorus element, potassium fixation in soil and pass through three kinds of leaching, runoff and volatilization approach
Loss, so as to improve chemical fertilizer utilization ratio.
To achieve the above object, the technical scheme that the present invention takes is as follows：

For the particle of 120-140 mesh, chitosan powder is broken into the particle that particle diameter is 80-120 mesh, organobentonite is ground into particle diameter is
The particle of 120-140 mesh, high-molecule chelated accelerator poly-aspartic potassium is ground into the particle that particle diameter is 180-200 mesh；
（2）By step（1）In the feed particles that crush be added in Frame type stirrer and be thoroughly mixed, jacket steam heating
During to 70-80 DEG C, stop stirring, activation insulation 1.5-2.5h, obtain mixed material；
（3）By step（2）In mixed material carry out cooling warehouse, packaging and storage when to room temperature.
It is of the invention to be relative to the beneficial effect of prior art：
In raw material selection,（1）Macromolecule composite surface conditioner polyacrylic acid potassium, it is nonpoisonous and tasteless, not Pollution Plant, soil and
Underground water, there is significant water conservation, soil moisture conservation to soil.It is finally decomposed to carbon dioxide, water, ammonium nitrogen and potassium from
Son, without any residual.Moisture evaporation can be effectively prevented, is prevented erosion；The structure of soil can be improved, make the sandy soil of leak fertilizer
Improved with secondary salt affected soil, while promote edaphon to develop, improve the turnover utilization ratio of soil organic matter.
（2）Chitosan can promote absorption of the plant to nitrogen, phosphorus, potassium, strong plant part, shorten plant growing cycle.Chitosan and have
Machine fertilizer is used in mixed way, the characteristics of giving full play to its biodegradability and compatibility, is had to agricultural chemicals and chemical fertilizer and is increased
The effect of effect.Chitosan fertilizer can promote the increasing of beneficial bacterium such as cellulose-decomposing bacteria, lactic acid bacteria, actinomyces significantly after entering soil
It is raw, suppress the growth of harmful bacteria such as mould, der Pilz.Chitosan can effectively improve soil granular structure, effective conditioned soil
Earth, improve the living environment of crop, be a kind of multi-functional soil conditioner.（3）Macromolecule composite surface conditioner xanthans
It is that preferable thickener, suspending agent, emulsifying agent and forming agent enter after soil and met fertilizer after water in food and chemical industry
Coupling, acted synergistically together with methylcellulose and macromolecule composite surface conditioner Acritamer 940, chemical fertilizer nutrient is firmly solid
It is scheduled on around root system of plant, plant is on-demand, reduces the seepage and runoff of chemical fertilizer, improves chemical fertilizer utilization ratio, reduces chemical fertilizer
Agricultural non-point source pollution.（4）High-molecule chelated accelerator poly-aspartic potassium has good chelating ability, has very to N P and K
Good facilitation, object is made to the micro- fertilizer supply of chelating N P and K and zinc-manganese iron etc. by it and the activity of biology enzyme can be excited.
By chemical fertilizer nutrient controlled release powder produced by the present invention by 2-4% add fertilizer in, can be made into various different models it is low into
This environment-friendly type Loss-controlled fertilizer, after being manured into soil, water, fertilizer, soil fully lotus root are closed, and the N P and K in fertilizer is fixed in soil,
Nitrogen loss 40-50% can be reduced, reduces phosphorous loss 20-65%, reduces soil K loss by erosion 25-60%, improves utilization rate of fertilizer extremely
75%, the pollution of nitrogen, phosphorus element, potassium to water body and air, while water conservation, chesson are reduced, improves soil granular structure,
Culture fertility, promote the growth of beneficial bacterium in soil, suppress the growth of harmful bacteria, increase crop disease-resistant power.
