Method capable of maintaining spore activity in bacteria solution of plate long spore bacteria

Abstract

The invention discloses a method capable of maintaining spore activity in a bacterial solution of plate long spore bacteria. The method comprises the following steps of S1, putting a culture medium into a flexible plastic vacuum bag, carrying out irradiation sterilization, and filling a plate long spore bacteria fermentation bacterial solution into the flexible plastic vacuum bag; and S2, when thestrain fermentation end point is reached, providing the culture medium again. According to the method, the problem that the activity of strains is reduced during transportation in a bacterial solution form is solved, and meanwhile, the storage time is long.

Description

technical field [0001] The invention relates to the technical field of Discochospora bacterial liquid, in particular to a method capable of maintaining the viability of spores in the Discochospora bacterial liquid. Background technique [0002] Discochospora is a dodder pathogenic fungus. It can infect soybean dodder to make it sick and die, so as to achieve the purpose of controlling this weed. This bacterium was first discovered and applied by the Institute of Plant Protection, Shandong Academy of Agricultural Sciences, China. Soybean Cuscuta is a vicious parasitic weed that harms soybeans. It is widely distributed in major soybean-producing areas in China. Generally, the damage can reduce yield by 10-20%, and severe flakes will fail to harvest. Using Lubao No. 1 to control soybean dodder, the control effect is generally above 85%. The conidia of Shandong, Jiangsu, Anhui, Ningxia, Shaanxi, Hubei, Xinjiang, Hebei, Henan, and Lubao No. 1 were long oval, colorless, and sin...
