Method for preparing organic fertilizer from crop straws

Abstract

The invention discloses a method for preparing an organic fertilizer from crop straws, which comprises the following steps: crushing the crop straws, taking 70-140 parts of the crushed crop straws, carbonizing the crushed crop straws into 15-30% of semi-carbon, and adding 20-40 parts of microbial zymophyte and 10-20 parts of brown sugar water or bean cakes into the semi-carbon for fermentation; then taking 70-140 parts of poultry manure, adding 20-40 parts of microbial zymophyte and 10-20 parts of bean flour into the poultry manure, and fermenting; respectively taking 15-20 parts of fermented crop straw and 60-70 parts of fermented poultry manure, mixing the two materials, adding 6-10 parts of a carbon raw material, 10-15 parts of mineral fulvic acid or biochemical fulvic acid and 5-10 parts of attapulgite, uniformly stirring, and adding the mixture into a granulator for production; 3-5 parts of compound probiotics and 3-5 parts of lignic acid are added in the production process; air drying treatment is conducted after production is completed, and 3-5 parts of polyglutamic acid is sprayed in the process to accelerate air drying; the crop straw and the livestock manure are carbonized to serve as the base material of the organic fertilizer, so that the crop straw and the livestock manure can be fermented, and the maximum utilization value is exerted.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing organic fertilizers by utilizing crop straws. Background technique [0002] Organic fertilizers are mainly derived from plants and animals, and are applied to the soil to provide carbonaceous materials with plant nutrition as their main function. It is processed from biological materials, animal and plant wastes, and plant residues, which eliminates toxic and harmful substances, and is rich in a large number of beneficial substances. Provide comprehensive nutrition for crops, increase and renew soil organic matter, promote microbial reproduction, improve soil, and promote plant growth. [0003] The development of agriculture and animal husbandry has brought a lot of available resources. Livestock and poultry manure and crop straw can be used as raw materials for fertilizer preparation. Due to the unreasonable utilization of resources, livestoc...

Problems solved by technology

Livestock and poultry manure and crop straw can be used as raw materials for preparing fertilizers. Due to the unreasonable utilization of resources, livestock and poultry manure and crop straw have instead become sources of pollution, causing serious harm to water sources and soil

Livestock manure and crop straw are directly fermented as farmyard manure for planting and maintenance. The utilization rate is extremely low, and the fermentation of livestock manure and crop straw is not comprehensive enough to easily burn the plants
