Abstract

The invention relates to a method for planting sainfoin at a saline-alkali slope wasteland of an arid region. The method comprises the steps of district selection, preparation before seeding, seeding and irrigation. Under the semi-desert slope drop irrigation condition, sainfoin is planted without tillage, the sainfoin is planted to increase pasture yield while original vegetation is protected, and the quality of pasture is improved. Combined with the gentle slope semi-desert grassland environment, drop irrigation pipes are buried at intervals along contour lines with certain line spacing, through appropriate water supplementing, water lack in the seedling stage is relieved, the soil salinity of a planting region is faded to a certain extent, and seedling standing of the sainfoin is promoted. By means of the method, real tillage, salt content restraining through great water and other methods which damage the fragile semi-desert ecological environment are avoided, the sainfoin is planted at semi-desert saline-alkali soil under the water-saving drop irrigation measure, and a sustainable grazing meadow with biodiversity is formed.

Description

Technical field: [0001] The invention belongs to the field of plant cultivation, in particular to a method for planting red bean grass by no-tillage and drip irrigation on saline-alkaline barren slopes in semi-desert areas in arid regions. Background technique: [0002] Xinjiang is an important animal husbandry base in my country. Affected by overloaded grazing, grassland reclamation, and medicinal material mining, 600 million mu of existing natural grassland has been degraded to varying degrees, of which 200 million mu is seriously degraded. For the sustainable development of grassland animal husbandry, Xinjiang has gradually implemented projects such as herders' settlement since 1988, built artificial forage bases, and vigorously promoted the cultivation of forage. Xinjiang has a large mountainous area, and in the low mountain and gentle slope area, the precipitation can generally reach 200mm, and the semi-desert grassland formed is an important natural grassland. Moderat...
