Abstract

The invention relates to a method for planting medicago sativa in a salinization wasteland of an arid region. In the method, a low-salt environment for plant seed germination and seedling growth is created by using a mode of pressure drip irrigation, so that successful planting of plant seedlings in the saline-alkali soil is realized; shading protection is provided for the medicago sativa seedlings by planting the medicago sativa and suaeda salsa together and using the characteristic of fast growth of the suaeda salsa; and meanwhile, the salt content of the soil of the medicago sativa root zone is reduced by using high biomass and in vivo salt gathering characteristic of the suaeda salsa. By the method, the inhibition of the saline-alkali soil environment on medicago sativa seed germination and seedling growth is overcome, a condition for later normal growth of the medicago sativa is created, and a technical support is provided for production of high-quality pasture in Xinjiang and development of the animal husbandry.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for planting alfalfa by mixed sowing of Suaeda salsa in moderately salinized soil wasteland under the condition of drip irrigation. Background technique [0002] Xinjiang is a famous natural grassland in my country and one of the important animal husbandry bases in China. Xinjiang has an area of ​​720 million mu of usable natural pastures. Affected by climate change, overloaded grazing, grassland reclamation, and medicinal material extraction, 85% of them have degraded, of which 30% are severely degraded. In order to realize the sustainable development of animal husbandry, Xinjiang began to implement the project of returning grazing land to grassland at the end of the last century, increased the construction of artificial forage bases, vigorously promoted the planting of forage grass, and promoted the settlement of herdsmen. Alfalfa (Medicago sativa L.) is a...
