Description

Comamonas, compound microbial agent and application thereof Technical Field The invention belongs to the technical field of agricultural microbiology. Background The black land in northeast China has the excellent characteristics of high productivity and high natural fertility. However, due to the over-reclamation and unreasonable utilization in recent years and the adverse environmental effects of wind erosion, water erosion, freeze thawing erosion and the like, the black soil in northeast China is reduced in organic matter content and gradually thinned. The soil is protected by reducing disturbance to soil through returning straw to field, optimizing soil structure, promoting formation of organic matters, and ensuring good physicochemical property and strong productivity of soil. On the other hand, the protective cultivation technology is implemented in the northeast black soil area, crop straws can be effectively utilized, the problems of environmental pollution caused by excessive straw resources and local straw burning in the northeast area are solved, and meanwhile, soil can be fertilized. However, the straw has a complex structure, and the temperature of northeast is low throughout the year, so that the degradation capability of soil microorganisms on lignocellulose in the straw is limited to a certain extent. Most of the microbial inoculant products sold on the market at present have the problems of single function and the like, so that the member of the constructed microorganisms is clear, the straws can be decomposed in situ and efficiently under the low-temperature condition, and the compound functional microbial inoculant with the biocontrol and environment restoration capabilities is a problem to be solved in the field of the original straws in the northeast area and the black soil resource protection at present. Disclosure of Invention In view of the problems that the straw decomposition efficiency is low, straw resources cannot be reasonably utilized and soil is degraded under the low-temperature condition, the invention aims to provide the termite comamonas (Comamonas odontotermitis) GZL 91 with the preservation number of CGMCC NO.36852.
