Problems solved by technology

[0003] It is forbidden to drill wells to extract groundwater in the local area. We can only wait for the Yellow River water diversion. The Yellow River diversion water is used for regular irrigation and flood irrigation through channels. For halophytes with small seeds, timely water supply is required at the emergence stage, and the deep root growth rate in the early stage is lower than that in alkaline soil. Biological characteristics such as drought cracking speed, combined with semi-arid climate, make the cultivation of halophytic pastures a problem in this environment

Abstract

The invention relates to a method for constructing a slow release water-fertilizer reservoir for planting saline forage grass with alkaline earth in a drought area. According to the method, intensivealkaline earth in an inland drought area is selected, the slow release water-fertilizer reservoir is constructed by high-ridge furrowed field construction, furrowing, organic material filling, film covering and intermittent watering, not only are water and fertilizers provided for in-season plants, but also nutrient substances are continuously accumulated to form a long-acting slow release water-fertilizer reservoir through multiple years of implementation, and a substance basis is made for development of organic matter enriched soil textures from cracked alkaline earth; border irrigation, watering and seed sowing are implemented, a germination environment of halophyte seeds under natural conditions such as wet staining and lighting can be simulated; organic material furrow filming and high-density plant zones are combined to form full covering of the alkaline earth; with the combination of halophyte phenology, irrigation regime and local weather, moisture requirement relay of artificial irrigation and seasonable water falling plants in growth periods can be completed, and water and cost can be greatly saved; salt absorption plants are cut to make plant salt containing silage to recycle the alkaline earth, then use and improvement of the alkaline earth can be achieved, and a technical way is provided for development of alkaline earth in the drought area.

Description

technical field [0001] The invention discloses a method for planting halophytic pasture in alkaline soil, in particular to a method for planting saline pasture in strong alkaline soil in arid areas by building a slow-release water-fertilizer reservoir, belonging to the field of agricultural planting in arid areas. Background technique: [0002] In the arid area irrigated by the Yellow River water, due to the climate, soil parent material, and the weak alkalinity of the Yellow River water in the middle and lower reaches, a large area of ​​cracked alkaline soil is formed. The soil is clear, the thickness of the silty clay on the surface is more than 10m, the land is salinized, and the water permeability of the structure is extremely poor. Wuyuan County, Inner Mongolia is a distribution area of ​​heavy alkaline soil. In some areas, sunflower and other alkali-resistant crops suffer from serious lack of seedlings, broken ridges, and no harvest. The introduction of saline pasture ...
