Embodiment 1

[0022] Mix 200kg of cow dung, 400kg of shrimp powder and 400kg of soy sauce dregs to obtain a mixed material, wherein the soy sauce dregs are crushed and pretreated, the particle size of the pulverized soy sauce dregs is 0.1-1.5cm, the moisture content of the mixed material is 60%, and the total carbon The ratio of content to total nitrogen content is 25:1, and VT microbial agent is added according to 0.2% of the weight of the mixed material to carry out aerobic fermentation. The mixed material is piled into strips or trapezoids for fermentation. If piled into strips, the pile height is 70-80cm, the bottom width is 120-150cm, and the length is not limited. If piled into trapezoids, the pile height is 45-50cm, length and width unlimited. During the process of aerobic fermentation and composting, the change of material temperature should be observed. When the temperature of the center of the material heap rises above 50°C, the compost should be turned every 2 to 3 days, and the ...

Embodiment 2

[0024] Cow dung, shrimp powder and soy sauce residue are mixed to obtain a mixed material, wherein the soy sauce residue is crushed and pretreated, the particle size of the crushed soy sauce residue is 1.5-2 cm, the moisture content of the mixed material is 55%, the total carbon content and total nitrogen The content ratio is 20:1, and the VT microbial bacterial agent is added according to 0.1% of the weight of the mixed material to carry out aerobic fermentation. The mixed material is piled into strips or trapezoids for fermentation. If piled into strips, the pile height is 70-80cm, the bottom width is 120-150cm, and the length is not limited. If piled into trapezoids, the pile height is 45-50cm, length and width unlimited. During the process of aerobic fermentation and composting, the change of material temperature should be observed. When the temperature of the center of the material pile rises above 50°C, turn the pile once every 2 to 3 days, and turn the pile continuously...

Embodiment 3

[0026] Cow dung, shrimp powder and soy sauce dregs are mixed to obtain a mixed material, wherein the soy sauce dregs are crushed and pretreated, the particle size of the pulverized soy sauce dregs is 0.5-1.5 cm, the moisture content of the mixed material is 65%, the total carbon content and the total The nitrogen content ratio is 35:1, and the VT microbial agent is added according to 0.5% of the weight of the mixed material to carry out aerobic fermentation. The mixed material is piled into strips or trapezoids for fermentation. If piled into strips, the pile height is 70-80cm, the bottom width is 120-150cm, and the length is not limited. If piled into trapezoids, the pile height is 45-50cm, length and width unlimited. During the process of aerobic fermentation and composting, the change of material temperature should be observed. When the temperature of the center of the material heap rises above 50°C, the compost should be turned every 2 to 3 days, and the compost should be ...

Abstract

The invention relates to an organic fertilizer with high nutrient content for organic rice planting and a preparation method thereof. The preparation method comprises the following steps: (1) mixing soy sauce residue with cow dung and shrimp meal, thereby obtaining a mixture, the moisture content of the mixture is 55%-65% and the ratio of total carbon content to total nitrogen content of the mixture is (20-35):1; (2) inoculating the mixture obtained in the step (1) with aerobic fermentation bacteria, and then performing aerobic fermentation. According to the invention, the fermentation periodduring the preparation process of the organic fertilizer is obviously shortened, the quality of compost products is effectively improved and the prepared organic fertilizer is capable of effectively promoting quality and yield of rice.

Description

technical field [0001] The invention relates to an organic fertilizer with high nutrient content used for planting organic rice and a preparation method thereof. Background technique [0002] Excessive use of chemical fertilizers in my country has caused multiple problems such as agricultural environmental pollution and farmland degradation. The Ministry of Agriculture launched an action plan to replace chemical fertilizers with organic fertilizers, which aims to improve soil fertility and improve the quality of agricultural products by reducing the use of chemical fertilizers and increasing organic fertilizers. Organic agriculture is an agricultural production model in which organic fertilizers must be used. Based on the principle of coordinated development of the agricultural ecological environment, the use of organisms obtained by genetic engineering and their products, artificially synthesized chemical pesticides, fertilizers, growth regulators and feed additives is prohi...
