My county is located in western Heilongjiang Province, 92 acres of grassland to produce sheep-based. For a long time, due to the transitional use, grassland has been continuously degraded, alkalized and alkalized, accounting for 25% of the total grassland. Alkalis grassland are mostly grazing grazing grassland, which is characterized by sparse Leymus chinensis grass, low, alkali spot contiguous, rusty grass. How to manage such alkalized grasslands has long been explored. Since the late 1970s, our county has succeeded in the comprehensive management of alkalified grassland, which is mainly planted with alkali-spotted stargrass, so far it has managed to treat 200,000 mu of alkalified grassland with an average increase of mu
