Biogas slurry also contains a variety of microorganisms, beneficial bacteria, various hydrolytic enzymes, certain plant hormones and secreted active substances that have a certain inhibitory and killing effect on many harmful pathogens and insect eggs of plants, and has an inhibitory effect on some plant diseases and insect pests. Biogas slurry is the residual liquid after anaerobic fermentation, which contains more residues. If it is directly mixed with chemical nutrients without treatment, it will affect the quality requirements of biogas slurry organic fertilizer.
