Abstract

The invention relates to a planting method for salt-tolerant forage grass with brackish water irrigation in saline-alkali sand wasteland. The method comprises the steps of choosing the saline-alkali sand wasteland with rich brackish shallow diving resources in arid inland areas, by screening saline forage plants, and developing the saline-alkali sand wasteland to plant the saline forage by the use of brackish shallow diving. According to the planting method for the salt-tolerant forage grass with brackish water irrigation in the saline-alkali sand wasteland, resource utilization of the idle brackish water and the saline-alkali sand wasteland is achieved, and an ecological efficient agricultural mode of comprehensive utilization of the saline-alkali sand wasteland and the brackish water is built, and the method has good guide value to both animal husbandry development and sand wasteland greening in rural areas with insufficient arable land.

Description

technical field [0001] The invention discloses a method for planting salt-tolerant forage grass by brackish water irrigation in saline-alkaline sand wasteland, in particular to a method for developing brackish shallow diving and planting salt-tolerant plants in saline-alkali sand wasteland. Background technique [0002] Xinjiang is a typical desert oasis irrigated agricultural area, where agricultural water consumption accounts for 95% of the total water consumption. The lack of water resources and the fragile ecological environment have seriously restricted the sustainable development of regional agriculture. In order to alleviate the growing water supply contradiction, the agricultural water sector has turned its attention to the development and utilization of brackish water and salt water resources. [0003] Xinjiang is a large animal husbandry area, but the overall development level of animal husbandry is still relatively low. Small area of ​​forage land, low yield, and...
