Abstract
The invention provides a complex control type long-acting controlled-release organic and inorganic biological fertilizer and belongs to the technical field of fertilizers. A raw material formula comprises 24-28 parts of urea, 6-8 parts of monoammonium phosphate, 6-8 parts of potassium sulfate, 55-65 parts of chicken manure fermented fertilizer, 7-9 parts of wood charcoal powder, 1.8-2.2 parts of calcium superphosphate, 0.8-1.2 parts of bentonite and 1 part of solid inoculant. The complex control type long-acting controlled-release organic and inorganic biological fertilizer has the beneficial effects that firstly, a nitrogen phosphorus and potassium fertilizer and the wood charcoal powder are mixed and granulated; the wood charcoal powder has the adsorption function so that fertilizer nutrients can be slowly released; the outer surfaces of initial grains are covered by a mixture of the calcium superphosphate and the bentonite to control the releasing of the nutrients; the chicken manure fermented fertilizer is used for covering the grains and then the solid inoculant is sprayed; the inoculant can control the releasing of nitrogen, phosphorus and potassium; and then the outer surface of the inoculant is covered by the mixture of one layer of the calcium superphosphate and the bentonite, so that the complex control type long-acting controlled-release organic and inorganic biological fertilizer is formed through a plurality of times of slow release and controlled release.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind ofly adopt coated release-controlled, adsorption sustained-release and biological slow-released to reach the multiple control type long-acting slow-release organic-inorganic bio-fertilizer of comprehensive slow release effect.
Background technology
China is a large agricultural country, and fertilizer occupies very important status in China's grain-production, is goods and materials investment maximum in peasant's productive investment.But, due to the production of fertilizer and the restriction of operation technique, cause the nutrient in fertilizer effectively not brought into play, soil fertility is declined, utilization rate of fertilizer reduces, and ecotope is destroyed.The science of China production at present and Fertilization Level entirety are also not high, still there is the phenomenon of blindly applying fertilizer in some areas, manure resources waste is serious, agriculture production cost increases, benefit reduces, and causes quality of agricultural product to decline, pollution of ecological environment, acceleration soil quality decline, directly affects Continued Increasing Grain Yield, agriculture upgrading synergy, peasant's abridged edition and increases income and agricultural product quality and safety.
Along with improving constantly of living standards of the people, the requirement that especially people improve quality of life, production safety, non-harmful green food are all come at develop actively sustainable agriculture in the whole world.Produce requirement in green food process and need not or use less chemical fertilizer, chemical pesticide and other chemical substance as far as possible.It requires fertilizer must first protect and promote the growth of subject and the raising of quality; Secondly do not cause subject to produce and accumulation objectionable impurities; The 3rd, ecotope is had no adverse effects.
Therefore, occurred at present many new-type fertilizers, had composite fertilizer, fertilizer, bio-fertilizer, compound organic and inorganic fertilizer, biological organic fertilizer, organic-inorganic bio-fertilizer, slow-release fertilizer, Controlled Release Fertilizer etc., these fertilizer are each has something to recommend him, differ from one another, but equal Shortcomings part in general.Composite fertilizer's utilization ratio is very low, cause serious waste and pollution, although the fine nutrient of fertilizer is inadequate, bio-fertilizer need to be using nutrient as basis, and the fertilizer efficiency period of various organic and inorganic fertilizers or organic bio-fertilizer is short, the effect of various controlled releases or slow-release fertilizer does not meet plant growth requirement yet.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, a kind of coated release-controlled, adsorption sustained-release and biological slow-released to reach the multiple control type long-acting slow-release organic-inorganic bio-fertilizer of comprehensive slow release effect that adopts is provided, to make better crop obtain essential fertilizer nutrient in growth cycle whole process, promote the normal growth of crop in each stage of growth.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is one control type again long-acting slow-release organic-inorganic bio-fertilizer, it is characterized in that its composition of raw materials is: 1 part of urea 24-28 part, monoammonium phosphate 6-8 part, potassium sulfate 6-8 part, fowl dung fermentation fertilizer 55-65 part, wooden carbon dust 7-9 part, calcium superphosphate 1.8-2.2 part, wilkinite 0.8-1.2 part, solid fungicide.
The preparation method of described fertilizer is.
(1) pulverize: each raw material is pulverized respectively.

(3) screening: by granule sieving, get the particle that granularity is 1.5-2.5mm, underproof returning pulverized granulation again.
(4) the dressing of whitewashing: add water and stir into slurry after the wilkinite of 40% calcium superphosphate and 40% is fully mixed, then evenly whitewashing is wrapped in the particle surface after granulation.
(5) the granulation of rolling: the particle after whitewashing is admixed to the granulation of rolling in fowl dung fermentation fertilizer powder, fowl dung fermentation fertilizer is wrapped in to surface.
(6) screening: by granule sieving, get the particle that granularity is 2.5-3.5mm, underproofly return to the granulation of again rolling.
(7) whitewashing bag bacterium: solid fungicide is mixed to wet rear evenly whitewashing at the particle surface with after fowl dung fermentation fertilizer parcel.
(8) the dressing of whitewashing: add water and mix slurry after the wilkinite of 60% calcium superphosphate and 60% is fully mixed, then the even particle surface of whitewashing after granulation.
(9) dry: oven dry that particle is rolled in hot blast, hot blast temperature is 60-80 DEG C, treats that water ratio is less than 8%.
Its further preferred version is one control type again long-acting slow-release organic-inorganic bio-fertilizer, it is characterized in that its composition of raw materials is: 26 parts, urea, 7 parts of monoammonium phosphates, 7 parts of potassium sulfate, 60 parts of fowl dung fermentation fertilizers, 8 parts of wooden carbon dusts, 2 parts of calcium superphosphate, 1 part of wilkinite, 1 part of solid fungicide.
The preparation method of described fertilizer is.
(1) pulverize: each raw material is pulverized respectively.
(2) stirring-granulating: by urea, monoammonium phosphate, potassium sulfate and the abundant mix and blend of wooden carbon dust, the granulation of then rolling.
(3) screening: by granule sieving, get the particle that granularity is 2mm, underproof returning pulverized granulation again.
(4) the dressing of whitewashing: will 0.8 part of calcium superphosphate and 0.4 part of wilkinite add water after fully mixing and stir into slurry, then evenly whitewashing is wrapped in the particle surface after granulation.
(5) the granulation of rolling: the particle after whitewashing is admixed to the granulation of rolling in fowl dung fermentation fertilizer powder, fowl dung fermentation fertilizer is wrapped in to surface.
