Abstract

The invention provides a method for preparing an EM bio-organic fertilizer by use of biogass slurry. The method comprises the following steps: adding an EM stock solution and an EM nutrient fluid into biogass slurry, and cultivating the biogas slurry by EM to obtain a bio-organic fertilizer, wherein the mass ratio of biogas slurry, the EM stock solution and the EM nutrient fluid is (95-105): (2-6): (0.5-1.5). As the EM cultivation mode is adopted, the method for preparing the EM bio-organic fertilizer by use of biogass slurry has the advantages of being convenient, simple, easy to operate and the like. The bio-organic fertilizer contains rich organic matters and lots of beneficial bio-funguses, can play a soil improvement role, can accelerate decomposition of the organic matters, has the advantages of being rich in nutrition, being easy to be absorbed by plants, improving the yield and the quality of crops and the like, is a leaf fertilizer with comprehensive nutrients and can treat and control some plant diseases and insect pests of the crops.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for preparing EM bacteria bio-organic fertilizer from biogas slurry and the organic fertilizer. Background technique [0002] At present, most of the technologies in China only carry out anaerobic fermentation of animal manure and straw, and the methane gas produced is collected and burned or used for power generation. The biogas residue and biogas slurry are not recycled and reused. The biogas slurry itself is a threat of water pollution. The biogas slurry directly enters the soil and water, which will have potential pollution risks to the surrounding surface water and groundwater. Some data show that when the biogas slurry is directly applied to the soil, although the soil can absorb part of the ammonium nitrogen, most of the ammonium nitrogen can still seep into the lower water layer and infiltrated water with the water flow, causing nitrogen pollution to the soil and groun...
