Problems solved by technology

Firstly, the long-term application of biogas slurry in large quantities will cause the accumulation of heavy metals and thus pollute the soil; secondly, due to the imbalance of nutrients in the biogas slurry and the high content of nitrogen and phosphorus, long-term application will cause the enrichment of nitrogen and phosphorus, resulting in soil compaction. Rainwater infiltration pollutes water bodies

Abstract

The invention discloses a disease preventing and resisting efficient biogas slurry fertilizer and a preparation method thereof. The disease preventing and resisting efficient biogas slurry fertilizer is formed by fermenting biogas slurry through a microbial solution, the ratio of bacillus amyloliquefaciens to bacillus subtilis in the biogas slurry fertilizer is 0.8 to 1.2, and the total quantity of viable bacteria in every milliliter of the biogas slurry fertilizer is larger than 2*108. The preparation method of the disease preventing and resisting efficient biogas slurry fertilizer includes the steps that waste molasses with the mass accounting for 5-8% of the biogas slurry is added, industrial glucose with the mass accounting for 1-2% of the biogas slurry is added, inoculation of bacillus amyloliquefaciens and bacillus subtilis is carried out, and the efficient biogas slurry fertilizer is prepared through fermentation, wherein every gram of the product contains the live bacteria with the total quantity being 2.0*108. The biogas slurry fertilizer can provide balanced nutritional matter and can exert the effects of preventing and controlling fungal diseases, resisting continuous cropping and promoting growth, the use amount of the biogas slurry is reduced, and soil hardening and accumulation of harmful matter are avoided.

Description

technical field [0001] The invention relates to a high-efficiency biogas slurry fertilizer that prevents plant fungal diseases and promotes plant growth, and belongs to the technical field of bio-organic fertilizer preparation. Background technique [0002] Biogas slurry refers to the liquid by-products of agricultural and forestry waste, manure from livestock and poultry farms and aquaculture sewage produced by biogas engineering through anaerobic fermentation. With the development of intensive aquaculture, more and more biogas slurry is produced. The main treatment method of biogas slurry in my country is returning to the field for utilization. The solid content of biogas slurry is about 1%. Although it is rich in nutrients and has a certain inhibitory effect on some plant pathogenic fungi, the content of nutrients and disease-resistant components is small, so the application amount is large. Long-term large-scale application of biogas slurry will bring safety and enviro...
