Abstract

The application discloses a microbial preparation for straw decomposition and soil nutrient improvement and application thereof, and relates to the technical field of agricultural waste resource utilization and soil improvement. Streptomyces sp. PLXSD-1, and the microbial preparation is prepared by compounding the streptomycete and a tobacco leaf extract, and the microbial preparation can promote straw degradation and improve soil nutrient conditions. The activity of the streptomycete is improved by using the tobacco leaf extract, and the rapid decomposition of the straw and the supply capacity of soil nitrogen and phosphorus are improved. Specifically, compared with the streptomycete alone, the phosphorus solubilizing capacity is increased by 19.43% and the straw degradation rate is significantly increased by 25.82% after the streptomycete is compounded with the tobacco leaf extract. In addition, the streptomycete PLXSD-1 and the tobacco leaf extract have a synergistic effect on improving the straw degradation rate.
