Abstract

The present invention discloses a high-nutrient organic fertilizer and a preparation method thereof, wherein 850-1100% by weight of chicken manure, 250-400% by weight of edible fungi bag and 150-250% by weight of sawdust are subjected to turning aerobic fermentation with a VT-200 composite bacterial agent to prepare the product, and the effective components in the product respectively comprise, by weight, 4.0-5.0% of nitrogen, 2.0-3.0% of phosphorus, 3.0-5.0% of potassium, and 45-60% of organic matters. According to the present invention, the total nutrient content (nitrogen, phosphorus and potassium) in the organic fertilizer final product is up to more than or equal to 12%, and is increased by more than or equal to one time compared with the nutrition content in the existing organic fertilizer on the market; the fertilizer application amount can be reduced, and the storage and transportation cost and the fertilizer application labor cost can be reduced; and the application range of the selected fermentation bacteria on the organic raw material is wide, and in the case of high nitrogen, the nitrogen loss can be reduced, the fermentation temperature increase is rapid, and the fermentation time is short.

Description

A kind of high nutrient organic fertilizer and preparation technology thereof

Technical field

The invention belongs to field of chemical technology, be specifically related to a kind of high nutrient organic fertilizer and preparation technology thereof.

Background technology

Fertilizer is obtained by pile fermentation by coming from natural organic solid castoff (comprising work, agricultural wastes, aquaculture ight soil, domestic refuse etc.).Its nitrogen of existing compoiste fertilizer, phosphorus, potassium total nutrient only have 4 ~ 6%, and the major cause that its total nutrient difficulty improves is that the N P and K total nutrient of the existing source of manure is general all lower on the one hand, is be not applicable to the fermented bacterium of C/N than low material on the other hand.Existing fermenting agent general requirement material C/N, than about 25, can cause fermentation time very long for C/N than the material being less than 20, or fermentation not exclusively.If adopt the starting material of high C/N ratio, its nutrient content of the fertilizer produced just cannot improve.Therefore, only have the fertilizer of low nutrient at present, and there is no the fertilizer supply of high nutrient.But use nitrogen, phosphorus, this fertilizer that potassium total nutrient is low just must strengthen amount of application, just must add carrying cost and the fertilising recruitment cost of fertilizer, therefore developing high nutrient organic fertilizer is the task of top priority.

Summary of the invention

The object of the present invention is to provide a kind of high nutrient organic fertilizer.To realize its nitrogen, phosphorus, potassium total nutrient improve greatly; Fertilising consumption can be reduced, reduce carrying cost and the fertilising recruitment cost of fertilizer; And the fermented bacterium selected is that a kind of organic raw material is applied widely, can reduce the loss of nitrogen when high nitrogen, leavening temperature rises fast, and fermentation time is short.

High nutrient organic fertilizer of the present invention is considered to be worth doing by following weight ratio by chicken manure, edible fungi residues, saw art: chicken manure 850-1100, edible mushrooms bag 250-400, wood sawdust 150-250, through the product that VT-200 composite fungus agent turning aerobic fermentation is made, in product, the weight percent of various effective constituent respectively: nitrogen 4.0-5.0%, phosphorus 2.0-3.0%, potassium 3.0-5.0%, organic 45-60%.

The production method of high nutrient organic fertilizer, comprises the following steps:

(1) be: chicken manure 850-1100, edible mushrooms bag 250-400, wood sawdust 150-250 evenly mix and be stacked in fermenter, interpolation per ton 2 kilograms of VT, 180 composite fungus agents by weight ratio, regulate moisture to stir once to 40 ~ 50%;

After (2) 2 days, temperature rises to 60 ~ 70 DEG C, starts to carry out turning over throwing every day, carries out aerobic fermentation 15 ~ 17 days; Slow decline is started to temperature; Color becomes brown or brown, and moisture is reduced to less than 35%, enters after-ripening;

(3) dry sub-sieve and become fertilizer finished product.

Described chicken manure is dried poultrymanure or wet chicken manure or the mixture of the two, and in chicken manure, the weight percent of various effective ingredient respectively: nitrogen 4.0-5.0%, phosphorus 2.0-3.0%, potassium 3.0-5.0%, organic 45-60%.

The carbon-nitrogen ratio of described edible mushrooms bag more than 50, without living contaminants.

Advantage of the present invention: the claimed range of VT200 composite fungus agent to carbon-nitrogen ratio that we adopt is larger, and its C/N well can ferment to organic raw material 15 ~ 30; Can reduce the loss of nitrogen when high nitrogen, leavening temperature rises fast, and fermentation time is short.The product that the main raw material of organic fertilizer resource that we use is nitrogen, the mixture of phosphorus, chicken manure that potassium total nutrient content is high, sawdust and edible mushrooms ferments through turning, in finished product, nitrogen, phosphorus, potassium total nutrient content are up to more than lO016; It is more than doubled than fertilizer nutrient content existing on market, more obvious to the production-increasing function of farm crop; Outward appearance commodity and the inherent nutritive value of its agricultural-food produced are higher; Its fertilizer efficiency is more steady lasting, and just nature can be higher for the fertilising economic benefit of peasant.Shown by field experiment, the fertilizer efficiency period using fertilizer of the present invention is long, fertilizer efficiency is steady, disease and pest is few, agricultural product quality obviously improves.Use high nutrient organic fertilizer 200 kilograms as every mu, capsicum and be used as base manure, the basic requirement that can meet the nutrition supply in its all one's life, in capsicum throughout the growing season, other fertilizer is no longer executed except keeping the skin wet, just can make the result that capsicum is without stop, and color of the leather is beautiful is rich in gloss, output and conventional fertilizer application suitable; And do not occur that trace element deficiency is held up, particularly its quality is than using being significantly improved of common fertilizer: green capsicum, the thick fertilizer of red pepper meat are peppery, vitamin-mineral rich content, retinol1 00 milligram, vitamins C 450 milligrams, mineral calcium 24 milligrams.Other VITAMIN and mineral substance are also than the height using common fertilizer.

Below specific embodiments of the invention are described further.
