Improvement and Application of Leymus Chinensis Promoter in Meadow Grassland of Hinggan League
In May 2023,the Hinggan League Forestry and Grassland Workstation conducted a fertilization improvement technology trial for the degenerated Leymus chinensis grasslands in Horqin Right Wing Front Banner using a Leymus chinensis promoter developed by the Institute of Botany,Chinese Academy of Sciences.The trial set up a fertilized area and a control area,measuring the height,coverage,density,and above-and below-ground plant biomass of Leymus chinensis on July 3,August 3,and September 3.The study analyzed the differences in Leymus chinensis indicators between the fertilized and control areas to explore the treatment effects of the promoter and provide a scientific basis for the scientific management of degenerated Leymus chinensis grasslands.The results showed that the coverage,height,density,and above-and below-ground biomass of Leymus chinensis in the fertilized area were significantly improved,with Leymus chinensis transforming from a dominant species to a foundational species,altering the plant community structure.The promoter has a good improvement effect on natural degenerated Leymus chinensis grasslands and can be widely promoted for degenerated Leymus chinensis grasslands within the territory of Hinggan League.
