Liquid bacterial manure production technique by comprehensive utilization of marsh liquid and method thereof

Abstract

The invention belongs to the technical field of agricultural fertilizers, in particular to liquid bacterial manure produced by biogas slurry and a method thereof. The weight proportion of raw materials of the liquid bacterial manure is as follows: the ratio of biogas slurry to dry hyacinth powder to molasses fermentation wastewater to EM fungi is equal to 60-65 to 20-23 to 14.5-16 to 0.5-1.0. The EM fungi is adopted as a fermentation agent, so the liquid bacterial manure has a plurality of efficacies and characteristics: the liquid bacterial manure can be taken as a water flush fertilizer to spray roots of crops, can provide multiple kinds of nutrition and trace elements for the crops to promote the growing development of the crops, can be taken as a foliage fertilizer to improve the content of chlorophyll, strengthen the photosynthesis, improve the yield, can be taken as a nuisanceless cultivation nutrient fluid to realize the complete nuisanceless cultivation, and reutilize resources of the biogas slurry, hyacinths in rivers and domestic waste and is environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a liquid bacterial fertilizer produced from biogas slurry and a method thereof. Background technique: [0002] Biogas digesters provide a large amount of biogas fuel for rural areas every year, and biogas production projects also produce a large amount of biogas slurry. However, the existing fermentation and biogas production projects discharge a large amount of biogas slurry and biogas residues that have not been comprehensively utilized as resources; the discharge of biogas slurry and biogas residues promotes the rapid growth of water hyacinth, leading to flooding of water hyacinth, which not only pollutes river water sources , also affects river traffic. In addition, there are more than 2,000 counties in my country, and the sown area of ​​crops is more than 2 billion mu. At present, the annual application of chemical fertilizers in my country is more than 40...
