AI Technical Summary
Existing microbial agents for the ecological restoration of degraded grasslands suffer from problems such as limited functionality, insufficient compatibility between carrier selection and microbial functional groups, and poor strain adaptability, resulting in unstable growth-promoting effects.
Develop an organic carrier root-rhizosphere growth-promoting microbial agent containing root-promoting bacteria such as Bacillus terracotta K4, Bacillus 9-3-1, Bacillus safortus 11-5-4, and Halomonas L31, as well as rhizosphere growth-promoting bacteria such as Serratia marcescens 5, Serratia marcescens 23, Cossackia covani 11, and Enterobacter hygroscopicus 24. Combine it with carbon-based organic fertilizer, cattle and sheep manure organic fertilizer, or biochar as a carrier to ensure the colonization and growth of the microbial agent in degraded grasslands.
It significantly increases vegetation community biomass and cover, promotes plant growth, improves the soil environment, increases soil nutrient content, and enhances grassland ecological restoration.
