Abstract

The invention discloses a dung fermentation slow release fertilizer, which is prepared from the following raw materials in parts by weight: 80-90 parts of rabbit dung, 50-55 parts of pigeon dung, 10-12 parts of tobacco juice, 10-12 parts of soybean molasses, 30-34 parts of slow release urea, 12-14 parts of slow release potassium chloride, 2-3 parts of borax, 2-3 parts of quicklime powder, 3-5 parts of plant ash, 3-4 parts of EM inoculant, 4-6 parts of coating agent and a proper amount of water. The fertilizer is prepared by combining organic materials such as rabbit dung and pigeon dung, an inorganic slow release quick-acting fertilizer and medium trace elements necessary for plants and performing fermentation treatment. By adopting the prepared fertilizer, the structure of soil can be improved, the fertilizer utilization ratio is increased, the drought resistance and disease resistance are enhanced, the environment of microorganisms in soil is improved, and good economical, social and environmental benefits are achieved. The prepared fertilizer has a slow release effect, so that the problems of too quick release, low utilization ratio and the like of the fertilizer in soil can be solved effectively.

Description

A kind of manure fermentation slow release fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of manure fermentation slow release fertilizer and preparation method thereof.

Background technology

Fertilizer is to provide the essential mineral element of one or more above plants, improves soil property, a class material of the level of increasing soil fertility, and is one of basic substance of agriculture production.The composite fertilizer that China produces at present, mainly to be formed by chemical fertilizer compounds such as nitrogen, phosphorus, potassium, after shortcoming is life-time service, not only can make the situation aggravation of the disease and pest of farm crop, also can cause that weeds grow wild, environmental pollution is serious, make the soil ecology imbalance of crop culture, cause the phenomenons such as soil compaction, form agricultural vicious cycle, restricted the Sustainable development of China's modern agriculture industry.Therefore the fertilizer that utilizes life fertiliser production, although be rich in organic matter, nutrient content is lower, can not meet the comprehensive demand of crop growth to nutrient, effect slowly, not remarkable, animal dung contains a large amount of objectionable impuritiess in addition, can not guarantee the safety of agricultural-food.In sum, fertilizer of the present invention.The decision of corresponding China Developing Sustainable Agriculture, in conjunction with the advantage of both fertilizer, in the raw material of manufacturing and technique, innovate, make to make fertilizer and have that joint is fertile, water saving, save labour, fertilizer efficiency lasting, promote that crop yield increases income, improves the advantage such as crop quality and resistance.

Summary of the invention

Fertilizer object of the present invention is that a kind of manure fermentation slow release fertilizer and preparation method thereof is provided.

Technical scheme of the present invention is as follows:

Fertilizer is made up of the raw material of following weight part: rabbit excrement 80-90, pigeon dung 50-55, cigarette foam 10-12, soy molasses 10-12, slow-release carbamide 30-34, slowly-releasing Repone K 12-14, borax 2-3, calcium lime powder 2-3, plant ash 3-5, EM microbial inoculum 3-4, coating agent 4-6, water are appropriate;

Described coating agent is made up of the raw material of following weight part: dimethyl silicone oil 12-15, butyl methacrylate 13-16, linking agent TAC1-2, nano-sized carbon 0.1-0.2, medical stone powder 1-2, boric acid 1-2; Its preparation method is that each raw material is mixed, and grinding distribution evenly and get final product.

The concrete steps of the preparation of fertilizer are as follows:

(1) after rabbit excrement, pigeon dung are mixed, after deodorizing is processed, mix with cigarette foam again, obtain mixture, for subsequent use;

(2) soy molasses is added in suitable quantity of water and mixed, obtain molasses water, access EM microbial inoculum, stirs, and obtains mixed bacteria liquid, for subsequent use;

(3) slow-release carbamide, slowly-releasing Repone K are mixed, must mix fertile, for subsequent use;

(4) borax, calcium lime powder, plant ash are added suitable quantity of water grind pulping, obtain mixed pulp, for subsequent use;

(5) mixed pulp of the mixing fertilizer of the mixed bacteria liquid of the mixture of step 1, step 2, step 3, step 4 and other remaining component are mixed, stir, 20-30 days ferments under natural condition, during this time every turning in 4-5 days once, after having fermented, dry, granulation.

Beneficial effect of the present invention:

Fertilizer of the present invention, adopt the organic materialss such as rabbit excrement, pigeon dung and inorganic slowly-releasing quick-acting fertilizer, the required middle trace element of plant to carry out combination, process by fermentation again, the fertilizer making can improve soil structure, improve chemical fertilizer utilization ratio, strengthen drought resisting and resistance against diseases, improve the environment of Soil Microorganism, there is good economy, society and environmental benefit.The fertilizer making also has slow releasing function, can effectively solve fertilizer and in soil, discharge the problems such as too fast, utilization ratio is low.

Specific embodiments

Below in conjunction with following embodiment, the present invention is described in further detail:

The raw material that takes following weight part (kg) is made: rabbit excrement 85, pigeon dung 53, cigarette foam 11, soy molasses 11, slow-release carbamide 32, slowly-releasing Repone K 13, borax 3, calcium lime powder 2, plant ash 4, EM microbial inoculum 4, coating agent 5, water are appropriate;

Described coating agent is made up of the raw material of following weight part (kg): dimethyl silicone oil 13, butyl methacrylate 14, linking agent TAC2, nano-sized carbon 0.1, medical stone powder 1, boric acid 2; Its preparation method is that each raw material is mixed, and grinding distribution evenly and get final product.

The preparation method's of fertilizer concrete steps are as follows:

(1) after rabbit excrement, pigeon dung are mixed, after deodorizing is processed, mix with cigarette foam again, obtain mixture, for subsequent use;
