Abstract

It is by chicken manure, edible fungi residues, wood sawdust by following weight percent the invention discloses a kind of high nutrient organic fertilizer and preparation method thereof：Chicken manure 850-1100 eats bacterium bag 250-400, wood sawdust 150-250, and through product made of VT-200 composite bacteria agent turning aerobic fermentations, the weight percent of various active ingredients is respectively in product：Nitrogen 4.0-5.0%, phosphorus 2.0-3.0%, potassium 3.0-5.0%, organic matter 45-60%.Nitrogen, phosphorus, potassium total nutrient content are up to 12% or more in the organic fertilizer finished product of the present invention；It is more than doubled than existing organic fertilizer nutrient content in the market；Fertilising dosage can be reduced, the carrying cost and fertilising recruitment cost of indignant fertilizer are dropped；And the fermenting microbe selected can reduce the loss of nitrogen to the applied widely of Organic Ingredients in the case of high nitrogen, fermentation temperature rises soon, and fermentation time is short.

Description

A kind of high nutrient organic fertilizer and its preparation process

Technical field

The invention belongs to field of chemical technology, and in particular to a kind of high nutrient organic fertilizer and its preparation process.

Background technology

Organic fertilizer is by being derived from natural organic solid castoff（Including work, agricultural wastes, aquaculture excrement, life Rubbish etc.）It is obtained by pile fermentation.Existing compoiste fertilizer its nitrogen, phosphorus, potassium total nutrient only have 4~6%, and total nutrient difficulty carries On the one hand the main reason for high is that the N P and K total nutrient of the existing source of manure is generally all relatively low, be on the other hand not to be suitable for C/ Fermenting microbes of the N than low material.Existing fermenting agent generally requires material C/N ratios 25 or so, for C/N than the object less than 20 Material can cause fermentation time very long, or fermentation is incomplete.And if using high C/N than raw material if produced have Its nutrient content of machine fertilizer can not just improve.Therefore, the organic fertilizer of only low nutrient, the organic fertilizer without high nutrient supply at present It answers.But apply the low this organic fertilizer of nitrogen, phosphorus, potassium total nutrient and just have to increase amount of application, fertilizer must be increased Carrying cost and fertilising recruitment cost, therefore it is the task of top priority to develop high nutrient organic fertilizer.

Invention content

The purpose of the present invention is to provide a kind of high nutrient organic fertilizers.To realize that its nitrogen, phosphorus, potassium total nutrient greatly improve； Fertilising dosage can be reduced, the carrying cost and fertilising recruitment cost of fertilizer are reduced；And the fermenting microbe selected is a kind of organic original Expect applied widely, can reduce the loss of nitrogen in the case of high nitrogen, fermentation temperature rises fast, and fermentation time is short.

The 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, bacterium bag 250-400, wood sawdust 150-250 are eaten, through product made of VT-200 composite bacteria agent turning aerobic fermentations, production The weight percent of various active ingredients is respectively in product：Nitrogen 4.0-5.0%, phosphorus 2.0-3.0%, potassium 3.0-5.0%, organic matter 45- 60%。

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

(1) it is with weight ratio：Chicken manure 850-1100, eats bacterium bag 250-400, wood sawdust 150-250, uniformly mixes and is stacked at In fermentation tank, 2 kilograms of VT of addition per ton, 180 composite bacteria agents adjust moisture and are stirred once to 40~50%；

Temperature rise starts to carry out turning over throwing daily, carries out aerobic fermentation 15~17 days to 60~70 DEG C after (2) 2 days；To temperature Start slowly to decline；Color becomes brown or brown, and moisture is reduced to 35% hereinafter, into after-ripening；

(3) drying sub-sieve becomes organic fertilizer finished product.

The chicken manure is the mixture of dried poultrymanure or wet chicken manure or the two, the weight percent of various effective ingredients in chicken manure It is respectively：Nitrogen 4.0-5.0%, phosphorus 2.0-3.0%, potassium 3.0-5.0%, organic matter 45-60%.

The carbon-nitrogen ratio of the edible bacterium bag is 50 or more, no living contaminants.

Advantages of the present invention：The VT200 composite bacteria agents that we use are bigger to the claimed range of carbon-nitrogen ratio, and C/N exists 15~30 can ferment to Organic Ingredients well；The loss of nitrogen can be reduced in the case of high nitrogen, fermentation temperature rises fast, hair The ferment time is short.The primary raw material for the organic fertilizer resource that we use is the high chicken manure of nitrogen, phosphorus, potassium total nutrient content, sawdust and edible The product that the mixture of bacterium ferments through turning, nitrogen, phosphorus, potassium total nutrient content are up to lO016 or more in finished product；It is more existing than in the market There is organic fertilizer nutrient content to be more than doubled, the production-increasing function of crops is become apparent from；The appearance of its produced agricultural product Commodity and inherent nutritive value higher；Its fertilizer efficiency is more steady lasting, and the fertilising economic benefit of peasant just naturally can higher. Show that the fertilizer efficiency period length using the organic fertilizer of the present invention, fertilizer efficiency is steady, pest and disease damage is few, agricultural product quality is bright by field experiment It is aobvious to improve.200 kilograms of high nutrient organic fertilizer is applied per acre such as capsicum and is used as base manure, can meet the nutrition supply in its all one's life substantially It is required that capsicum throughout the growing season, other fertilizer are no longer applied in addition to keeping the skin wet, the knot that capsicum can be made without stop Fruit, and color of the leather is beautiful rich in gloss, yield is suitable with conventional fertilizer application；And there is not trace element deficiency to help, especially It is its quality being significantly improved than application common fertilizer：The thick fertilizer of green capsicum, pimiento meat is peppery, and vitamin and minerals content is rich Richness, 00 milligram of retinol1,450 milligrams of vitamin C, 24 milligrams of mineral calcium.Other vitamin and minerals are also more normal than application Wanting for rule fertilizer is high.

Specific embodiments of the present invention are described further below.
