Embodiment 1

[0024] This embodiment includes the following steps:

[0025] Step 1) raw material preparation: by weight percentage, get the following raw materials for subsequent use:

[0026] 65% of livestock and poultry manure, 15% of shrimp and crab shell waste, 19.5% of straw, and 0.5% of compound microbial inoculum; Mixed in a weight ratio of 2:1:2:2;

[0027] Step 2) Mixing of raw materials: Concentrate the waste of shrimp and crab shells and crush them into 3-5mm particle size. The purpose of crushing is to reduce energy consumption and increase the yield. Mix the crushed waste of shrimp and crab shells with livestock and poultry manure evenly ;

[0028] Step 3) composting: fully mix the mixture obtained in step 2) with straw and composite microbial inoculum to form a trapezoid with a height of 1 meter, and control its water content in the range of 60-70% by weight fraction;

[0029] Step 4) Turning: During the composting process, the piles are turned repeatedly. The fermentation ...

Embodiment 2

[0031] This embodiment includes the following steps:

[0032] Step 1) raw material preparation: by weight percentage, get the following raw materials for subsequent use:

[0033] 84% of livestock and poultry manure, 5% of shrimp and crab shell waste, 10% of straw, and 1% of compound microbial agent; Mixed in a weight ratio of 2:1:2:2;

[0034] Step 2) mixing of raw materials: concentrating shrimp and crab shell waste, crushing them into 3-5mm particle size, and mixing with livestock and poultry manure;

[0035] Step 3) composting: fully mix the mixture obtained in step 2) with straw and composite microbial inoculum to form a trapezoid with a height of 1.2 meters, and control its water content within the range of 60-70%;

[0036] Step 4) Turning: During the composting process, the piles are turned repeatedly. The fermentation period is 30 days, and the finished product is obtained. The frequency of repeated turning is 3 to 5 times during the entire fermentation process, once ...

Embodiment 3

[0038] This embodiment includes the following steps:

[0039] Step 1) raw material preparation: by weight percentage, get the following raw materials for subsequent use:

[0040] 70% of livestock and poultry manure, 9.2% of shrimp and crab shell waste, 20% of straw, and 0.8% of compound microbial inoculum; Mixed in a weight ratio of 2:1:2:2;

[0041] Step 2) mixing of raw materials: concentrating shrimp and crab shell waste, crushing them into 3-5mm particle size, and mixing with livestock and poultry manure;

[0042] Step 3) composting: fully mix the mixture obtained in step 2) with straw and composite microbial inoculum to form a trapezoid with a height of 1.5 meters, and control its water content in the range of 60-70% by weight fraction;

[0043] Step 4) Turning: During the composting process, the piles are turned repeatedly. The fermentation period is 22 days, and the finished product is obtained. The frequency of repeated turning is 3 to 5 times during the entire ferme...

Abstract

The invention discloses chitin organic fertilizer produced by using livestock excrement and shrimp and crab shells and a preparation method thereof. The chitin organic fertilizer produced by using the livestock excrement and the shrimp and crab shells comprises, by weight percentage, the following raw materials of 65 to 84 % of the livestock excrement, 5 to 15 % of waste of the shrimp and crab shells, 10 to 20 % of straw and 0.5 to 1 % of microbial agent. The chitin organic fertilizer has the advantages that a strong induction effect in the respect of restraining tobacco bacterial wilt is achieved, the tobacco is promoted to generate system resistance under the environmental stress of soil-borne disease, the soil biological activity can be promoted to improve at the same time, the occurrence of the conditions of tobacco vascular bundle deformation and xylem blocking can be reduced to a certain extent, therefore the efficient prevention and control over the tobacco bacterial wilt are achieved, and the problems that the organic fertilizer is slow in taking effect, the effect is not obvious after the fertilizer is applied, and the fertilizer performance is not stable are solved. In addition, the invention further discloses the preparation method of the chitin organic fertilizer.

Description

technical field [0001] The invention relates to a chitin organic fertilizer produced by using livestock manure and shrimp and crab shells and a preparation method thereof. Background technique [0002] Tobacco is a special foliar economic crop with high economic value. Tobacco planting occupies an important position in my country's national economy. The growth of high-quality tobacco has strict requirements on soil type and its properties. With the improvement of people's living and consumption levels, the demand for high-quality and high-grade tobacco is increasing day by day. How to improve the output and quality of flue-cured tobacco has always been one of the main research contents of the tobacco industry. Due to the high soil multi-cropping index, the overall quality of the soil deteriorates seriously, the organic matter content decreases year by year, and the physical and chemical properties of the soil continue to deteriorate, which has become the reality of tobacco p...
