Problems solved by technology

However, the microbial fertilizer in the known technology only improves soil fertility and has no inhibitory effect on the pathogenic microorganisms existing in the soil.
However, there is currently no microbial agent or bacterial fertilizer used for the cultivation of colored peppers, and there is no literature report on the use of microbial agents for disease prevention and disease resistance of colored peppers.

Abstract

The invention discloses a composite microbial agent capable of remarkably facilitating color pepper yield and root rot resistance, and belongs to the technical field of microorganisms. The composite microbial agent consists of lactobacillus plantarum P-8, lactobacillus acidophilus KT-La9 and lactobacillus plantarum KT-Lp9. Compared with the prior art, the involved composite microbial agent has the following advantages and progressiveness: the root rot resistance of color pepper can be enhanced to achieve an efficient disease prevention effect; the quality (single fruit weight, single fruit transverse stems and vertical stems) of the color pepper can be improved; and the color pepper yield can be remarkably increased to bring more economic benefits.

Description

technical field [0001] The invention relates to a microbial bacterial agent, in particular to a composite bacterial agent capable of significantly promoting the yield of colored peppers and resisting root rot and an application thereof, belonging to the technical field of microorganisms. Background technique [0002] Colored pepper (Capsicum annuum var. grossum) is a variant of Capsicum genus in the family Solanaceae. Its flesh is plump and juicy, and its taste is sweet and slightly pungent. imported species. Colored peppers are rich in multivitamins (rich vitamin C) and trace elements. They can not only beautify the skin, but also have the effects of relieving heat, nourishing blood and promoting blood circulation. It is one of the important cultivated varieties of sightseeing agriculture and solar greenhouses in my country. With the development of the vegetable industry, the planting area of ​​colored peppers has continued to expand, and the production benefits have becom...
