A storage bottle used for biocontrol bacterium inoculant fermentation

Abstract

A storage bottle used for biocontrol bacterium inoculant fermentation is disclosed. The bottle includes a bottle cover, an upper bottle body, a lower bottle body and a support body. The bottle cover and the upper part of the upper bottle body are in threaded connection. The lower part of the upper bottle body and the lower bottle body are in threaded connection. The external wall of the upper bottle body is detachably connected to a sleeve that can be torn apart. The bottom end of the bottle cover can be abutted against the top end of the sleeve. The inner wall of the top end of the bottle cover is vertically fixedly provided with a cylinder having a pointed bottom end. The support body is a cylindrical shell the bottom end of which does not have an end surface and the top end surface of which is provided with a first through hole in the center. The diameter of the first through hole is greater than the diameter of the cylinder. The bottle opening inner wall of the lower bottle body isfixedly provided with a baffle ring. The support body is disposed on the baffle ring. The length of the cylinder is greater than a distance from the top of an upper bottle opening to the top of the support body, and when the bottom end of the bottle cover is abutted against the top end of the sleeve, the bottom end of the cylinder is above the top of the support body. The storage bottle achievesbiocontrol bacterium fermentation under non-laboratory conditions, and control effects of biocontrol bacteria on plant disease are improved.

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
