Abstract

The invention relates to the field of composite fertilizers, and concretely relates to a long-acting sustained-release composite fertilizer rich in organic materials. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000 mesh diatomite, 12-15 parts of ammonium humate, 8-10 parts of triple superphosphate, 5-6 parts of pumace, 6-8 parts of bean dregs, 4-5 parts of grass meal, 5-7 parts of lees vinegar, 1-2 parts of white sugar, 0.5-1 part of xylose, 18-20 parts of urea, 5-6 parts of borax, 8-10 parts of sodium carboxymethylcellulose, 6-8 parts of redispersible latex powder, 2-3 parts of ammonium ferric citrate, 8-10 parts of ammonium dihydrogen phosphate, 0.1-0.2 part of calcium stearate and 4-5 parts of an auxiliary agent. The raw materials of the composite fertilizer are rich in multiple organic materials, so that the soil activity is effectively improved, and the adverse influence of long-term fertilization on soil is improved; dual cladding on nutrient is formed by utilizing diatomite and a sustained-release coating agent in the production technology, so that nutrient is not easy to loss, the utilization rate is greatly improved; and release of nutrient is long-acting and efficient, and sufficient nutrient and balanced soil environment help to improve both crop output and quality, and the plantation benefit is increased.

Description

A kind ofly be rich in organic long-acting slow-release compound fertilizers

Technical field

The present invention relates to compound manure field, be specifically related to a kind of organic long-acting slow-release compound fertilizers that is rich in.

Background technology

In modern agricultural production, the figure of the composite fertilizer that is seen everywhere, it has, and nutrient content is high, minor component is few, utilization rate of fertilizer is high, the advantages such as convenient are used in storage, is promoting to play the part of important role aspect higher yield of crops stable yields.Slow-release compound fertilizer is a kind of important classification in composite fertilizer, the research emphasis of Ye Shi China Growth of Chemical Fertilizer Industry, its slowly-releasing principle is the hydrophobic substance at the coated thin layer in fertiliser granulates surface, thereby inner nutrient is discharged in soil slowly, constantly to farm crop, supply with nutrient, effectively raise the utilization ratio of fertilizer.Yet also there is certain shortcoming in existing slow-release compound fertilizer, be mainly manifested in nutrients ratio relatively fixing, be difficult to meet the different demands of all kinds of soil and all kinds of crops; Slow release effect is not fully up to expectations, does not mate, thereby reduced fertilizer efficiency with crop growth demand, affects plant growth, causes the underproduction reduction of income.

Summary of the invention

The object of the invention is to provide the slow-release compound fertilizer of a kind of low cost, efficient, environmental protection, and to achieve these goals, the technical solution used in the present invention is as follows:

A kind ofly be rich in organic long-acting slow-release compound fertilizers, it is characterized in that, this fertilizer is made by the raw material of following weight part: 1250-2000 order diatomite 10-15, ammonium humate 12-15, double superhosphate 8-10, pomace 5-6, bean dregs 6-8, grass meal 4-5, sake cake vinegar 5-7, white sugar 1-2, wood sugar 0.5-1, urea 18-20, borax 5-6, Xylo-Mucine 8-10, redispersable latex powder 6-8, ferric ammonium citrate 2-3, primary ammonium phosphate 8-10, calcium stearate 0.1-0.2, auxiliary agent 4-5;

Auxiliary agent is made by the raw material of following weight part: poultry feather 12-15, the sulphuric acid soln 30-35 of 30-40%, sodium hydroxide is appropriate, M-Zyme 0.15-0.2, Cuprocitrol 1-2, manganese citrate 1-2, zinc citrate 1-2, medical stone fine powder 20-22, water glass 5-6, preparation method is: first by the washing of poultry feather process, after high-temperature sterilization, pulverize, drop in sulphuric acid soln, hydrolysis 15-18h, in the hydrolyzed solution obtaining, add appropriate sodium hydrate regulator solution pH value to 6.5-7.0, and be heated to 50-60 ℃, add M-Zyme, after enzymolysis 12-15h, add Cuprocitrol, manganese citrate, zinc citrate, after stirring reaction 2-3h, add again water glass, continue to stir 30-40min, finally add again medical stone fine powder, dry after stirring, and grind 40-50min, obtain.

Described a kind of organic long-acting slow-release compound fertilizers that is rich in, its production stage is as follows:

(1) pulverize after pomace, bean dregs, sake cake vinegar are mixed, add grass meal, white sugar, wood sugar and appropriate water, carry out fermentative processing, fermentation is standby to material after becoming thoroughly decomposed completely;

(2) diatomite is mixed with waiting water of weight part, grinding 20-30min, makes diatomite slurry, adds subsequently ammonium humate, ferric ammonium citrate, borax, and after stirring, mixture anhydrates dryly, makes diatomite coating material;

(3) Xylo-Mucine is mixed with appropriate deionized water, be heated with stirring to 50-60 ℃, until Xylo-Mucine, dissolve completely after dispersion, add redispersable latex powder, calcium stearate, high-speed stirring 2-3h, makes slow release coating agent standby;

(4) other leftover materials are mixed with step (1), (2) gained material; drop into granulation in tablets press; and the slow release coating agent of preparing in the particle surface spraying step (3) making, the particle after coating is cooling through warm air drying, room temperature, gets product.

Beneficial effect of the present invention is: formula Raw wide material sources, take full advantage of in daily life production and common are machine raw material, not only reduced production cost, also farthest protected edatope, improve conventional composite fertilizer nutrient single fixing, and used for a long time the breakoff phenomenon to soil; In production technique, utilize diatomite and ammonium humate, ferric ammonium citrate, borax etc. to have the raw material of unique promoter action to adsorb mutually to plant growth, to prevent its too early invalid loss; With standby coated slow release formulations of mixed raw material such as Xylo-Mucine, redispersable latex powder, calcium stearates, possess good slow-release capability, more long-acting; Composite fertilizer prepared by the present invention utilizes diatomite and slow release coating agent nutrient to be formed dual coated, nutrient is difficult for running off, fertilizer efficiency is more lasting, and can spoiled soil balance, abundant organic mass-energy is promoted soil fertility, good growing environment effectively promotes plant growth, and plant growth is vigorous, and output and quality naturally obtain effectively and improve.
