Abstract

The invention relates to a solid microbial agent for preventing diseases and increasing yield of potatoes and a preparation method, wherein the active ingredient of the solid microbial agent for preventing diseases and increasing yield of potatoes includes bacillus amyloliquefaciens PHODG36, and also contains a dispersing agent, a wetting agent and filler. The invention also discloses the method for preparing the microbial agent, which comprises the following steps: preparing the bacillus amyloliquefaciens PHODG36 fermentation liquor by fermentation, and fully and uniformly mixing the preparedfermentation liquor with other raw materials in a mechanical mixing manner, thereby obtaining the solid microbial agent. The invention also discloses a specific effect of the solid microbial agent onprevention and treatment of potato verticillium wilt and yield. By using the solid microbial agent disclosed by the invention, the occurrence of potato verticillium wilt can be greatly reduced, and the yield of potatoes can be remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of microbial application, and in particular relates to a solid microbial agent for preventing diseases and increasing production of potatoes and a preparation method thereof. Background technique [0002] Potato is an important food crop in my country, which is of great significance to ensure food security. my country has listed potatoes as the fourth staple food after rice, wheat, and corn. Potatoes play a vital role in ensuring my country's food security, targeted poverty alleviation, planting structure adjustment, and agricultural industry transformation and upgrading. my country's potato planting area and total output both rank first in the world, but the yield per unit area is lower than the world average due to bottleneck factors such as pests and diseases. In recent years, soil-borne diseases caused by continuous cropping of potatoes tend to increase year by year, which directly affect the yield and ...
