Abstract

The invention provides a microbial fertilizer for increasing the yield of the ecological planting of potato and a preparation method thereof. According to a harmful organism control strategy based ona soil microecosystem, the invention utilizes complex microorganisms (such as bacillus, streptomycete and lactic acid bacteria) to ferment crop straws and livestock and poultry feces, so that the microbial fertilizer is obtained. The microbial fertilizer can effectively prevent and control bacterial soft rot of potato, bacterial ring rot of potato, deep scab of potato and the like caused by bacterial infection, thus effectively increasing the yield of the ecological planting of potato.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a microbial fertilizer for improving the ecological planting yield of potatoes and a preparation method thereof. Background technique [0002] Potato (Solanum tuberosum), also known as potato, belongs to the Solanaceae Solanaceae crop and is the fourth largest food crop in the world. Its output is second only to wheat, rice and corn. In 2015, with the launch of the potato staple food strategy in my country, the potato is becoming more and more important in the staple food of residents, and the demand for potatoes is also increasing. In recent years, the incidence of potato diseases caused by bacterial infection, such as soft rot, ring rot, and scab, has increased exponentially. At present, the main solutions for potato bacterial diseases are: seed disinfection, root irrigation disinfection and so on. The seed disinfection method mainly uses fungicides to soak potato seeds for steriliza...
