Method for forming grassland through mixed cultivation of rhizome type leguminous and gramineous forage grass for mowing and grazing in desert saline-alkali soil

Abstract

The invention relates to the field of plant (forage grass) establishment, in particular to a method for forming a grassland through mixed cultivation of rhizome type leguminous and gramineous forage grass for mowing and grazing in desert saline-alkali soil. When an artificial grassland is formed in a desert saline alkali land, rhizome type leguminous forage grass Qingshui medicago sativa, rhizometype gramineous forage grass awnless brome and elytrigia elongata are cultivated together in the ratio of 1:1:1, and according to the use requirements of soil preparation, sowing, field management, mowing and grazing, the cultivation is conducted. Through the reasonable collocation of the leguminous forage grass and the gramineous forage grass, the grassland is formed through mixed cultivation ofthe rhizome type leguminous and gramineous forage grass for mowing and grazing, a northwest desert saline alkali land is effectively improved to a certain extent, the quality of the forage grass is improved, the success rate of forming the grassland in the desert saline alkali land is ensured, and the stability of a grazing community and the trampling resistance of the grazing grassland are improved; the high-quality forage grass is provided for animal husbandry in the desert saline alkali area, feed shortage in winter and spring is alleviated, the input cost is reduced, the grazing pressure of a natural pasture is reduced, and the restoration of an ecological function of the natural pasture is promoted.

Description

technical field [0001] The invention relates to the field of plant (grass) establishment, in particular to a method for establishing rhizome-type bean and grass mixed-sowing, grazing, mowing and dual-purpose grassland in desert saline-alkali land. Background technique [0002] As a country with large grassland resources, my country has a total area of ​​nearly 6 billion mu of grassland. For a long time, because people have paid too much attention to the production function of grassland and neglected the ecological function of grassland, a series of serious problems have been caused, such as the large-scale degradation of natural grassland in my country and the imbalance of grass-livestock relationship. According to relevant research, compared with natural grassland, the establishment of high-quality and efficient artificial grassland can increase the yield of forage grass by 10 to 20 times. Therefore, the establishment of artificial grassland is expected to solve the bottle...

AI Technical Summary

Problems solved by technology

However, in the process of planting many artificial grasslands, there are single grass species and unscientific combination of mixed grass species, which leads to problems such as failure of grassland planting or low yield, especially the poor stability of grassland, which cannot realize long-term grazing or mowing. basic requirements
