The invention provides a method for quickly planting fracturing alkali soil switchgrass, which mainly aims to solve problems such as high alkalization degree, heavy texture and low fertility of fracturing alkali soil, low emergence rate of switchgrass and difficult planting. The technical scheme adopted by the method for quickly planting the fracturing alkali soil switchgrass, provided by the invention, comprises the following steps of: 1, laser soil leveling; 2, improved material application; 3, fertilizing in a composite organic and inorganic way; 4, deeply tilling and upturned soil sunning; 5, irrigating, salt leaching and alkali pressing; 6, soil preparing before transplantation; 7, seedling transplantation; 8, field management; 9, timely harvesting; 10, winter irrigating, alkali pressing and soil moisture conservation. According to the method for quickly planting the alkali soil switchgrass, disclosed by the invention, the quick planting of the switchgrass on the fracturing alkali soil can be realized, the switchgrass can well grow, a higher biological yield can be obtained at the same year when the switchgrass is planted, the method is suitable for planting the fracturing alkali soil switchgrass on Yinchuan Plain of Ningxia, the method is beneficial for resource development and utilization and biomass energy production, and obvious economic, social and ecological benefits are obtained.
