Carbon-based complex microbial inoculant and application thereof

Abstract

The invention relates to a carbon-based complex microbial inoculant and an application thereof. The carbon-based complex microbial inoculant comprises an aspergillus oryzae solid fermentation product,a zygosaccharomyces rouxii liquid fermentation product, a bacillus velezensis liquid fermentation product and biomass charcoal. According to the carbon-based complex microbial inoculant, the three fermentation products and the biomass charcoal are creatively compounded, the multiple components have a synergistic interaction effect, the carbon-based complex microbial inoculant is used in a soil remediation agent, and under the condition that no pesticide is introduced, the pH value of soil can be adjusted to be 7, so that the salt content of the soil is reduced, the content of organic mattersis increased, and the incidence rate of clubroot of green vegetables in the continuous cropping soil is reduced. The number of plasmodiophora brassicae woron in the continuous cropping soil treated with the soil remediation agent is remarkably reduced, the number of plasmodiophora brassicae woron in the root systems of the green vegetables in a harvesting period is remarkably reduced, and the diversity of microbial community species in the soil and the plant root systems is remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and relates to a carbon-based composite bacterial agent and its application, in particular to a carbon-based composite bacterial agent for soil restoration agent and its application. Background technique [0002] Clubroot, also known as root cancer, is currently the most serious worldwide soil-borne disease that harms cruciferous crops. It is caused by the infection of Plasmodium brassicae and has a wide range of hosts. It can harm cabbage, cabbage, radish, shepherd's purse, and cauliflower. And more than 100 kinds of cultivated and wild cruciferous plants such as rapeseed. After the pathogen infection, the parenchyma cells in the roots proliferate to form swollen roots, which mostly occur in the main root and lateral roots. The surface is smooth in the early stage, and the surface is cracked and rough in the later stage, which affects the water and nutrient absorption of the root sy...

Problems solved by technology

[0006] In the prior art, there are very limited strategies on how to more effectively prevent and cure clubroot or repair the soil where clubroot has occurred. Therefore, the development of a treatment raw material can be obtained locally, and the treatment effect is not limited by region. The green clubroot continuous cropping soil remediation agent and remediation method without the introduction of pesticides with antagonistic and inhibitory effects on pathogenic bacteria have important application value
