A kind of storage bottle for the fermentation of biocontrol bacterial agent

Abstract

The invention discloses a storage bottle for the fermentation of bio-control bacterial agent, which comprises a bottle cap, an upper bottle body, a lower bottle body and a support body; the bottle cap is threadedly connected to the upper part of the upper bottle body, and the lower part of the upper bottle body is threadedly connected to the lower bottle body The outer wall of the upper bottle is detachably connected with a sleeve that can be torn, and the bottom end of the bottle cap can be placed on the top of the sleeve; the inner wall of the top end of the bottle cap is vertically fixed with a cylinder whose bottom end is the tip; A cylindrical shell with a first through hole in the center of the top end face, the diameter of the first through hole is greater than the diameter of the cylinder; the inner wall of the bottle mouth of the lower bottle is fixed with a stop ring, and the support is arranged on the stop ring; the cylinder The length is greater than the distance from the top of the upper bottle mouth to the top of the support, and when the bottom of the bottle cap is against the top of the sleeve, the bottom of the cylinder is above the top of the support. The storage bottle for the fermentation of the bio-control bacteria agent of the present invention realizes the fermentation of the bio-control bacteria under non-laboratory conditions, and improves the control effect of the bio-control bacteria on plant diseases.

Description

technical field [0001] The invention relates to the technical field of fermentation of agricultural microbial inoculum, in particular to a storage bottle for fermentation of biocontrol bacterial inoculum. Background technique [0002] The use of chemical fungicides is an effective way to control crop diseases, but long-term use of chemical fungicides can easily pollute the environment and induce pathogens to develop drug resistance. In recent years, the use of biocontrol bacteria and their metabolites to inhibit the survival and activity of plant pathogenic bacteria has played an important role in the control of plant diseases. With the growing demand for pollution-free and pollution-free green food, and the introduction of national policies on reducing the use of chemical fertilizers and chemical pesticides, biological control has become another important control method after agricultural and chemical control. At present, many commercial biocontrol agents have come out, an...

Problems solved by technology

Biocontrol bacteria are often accompanied by a high proportion of bacterial death during the processing of bacterial agents, and whether it is processing liquid preparations or solid preparations, with the prolongation of transportation and storage time, the number of viable bacteria and the vitality of bacterial agents will decrease. , poor colonization ability of viable bacteria and other problems, which greatly affect the stability of the product quality of the bacterial agent and the performance of the biological control effect of the bacterial agent
