Methods for restoring ecosystem of alkali-saline grassland by adopting multifunctional vibration-type soil-improving machine

Abstract

The invention discloses methods for restoring an ecosystem of alkali-saline grassland by adopting a multifunctional vibration-type soil-improving machine, and relates to methods for restoring the ecosystem of the alkali-saline grassland. The methods solve the problems that the traditional methods for treating the alkali-saline grassland have high investment, slow response and single object and can only treat slight saline soil. The first method is to adopt vibration subsoiling to improve soil for slight alkali-saline grassland; the second method is to adopt vibration subsoiling and biochemical preparation spraying to improve the soil for medium alkali-saline grassland; and the third method is to adopt vibration subsoiling, biochemical preparation spraying and saline tolerant plant planting to improve the soil for severe alkali-saline grassland. The methods not only can save energy and reduce consumption, but also can improve the rate of soil pulverization, improve physical indexes of the soil, retain water, reduce alkali and salt, and inhibit accumulation of salt in the surface soil. By adopting the methods, the investment cost is reduced; and the methods have quick response, and can restore the slight alkali-saline grassland, the medium alkali-saline grassland and the severe alkali-saline grassland.

Description

technical field [0001] The invention relates to a method for restoring saline-alkali grassland ecology. Background technique [0002] For a long time, especially in the past 20 years, unreasonable grassland utilization systems and methods such as overgrazing, farmland reclamation, oil exploitation, and environmental pollution have resulted in serious grassland salinization, deteriorating ecological environment, reduced biodiversity, and comprehensive production capacity. As a result, the grassland's ecological functions such as windbreak and sand fixation and water and soil regulation will decline, and regional ecological security will be seriously threatened, which will directly affect the improvement of grassland industry and local people's living standards and quality of life. Salinization and secondary salinization have become one of the important obstacles to ecological environment construction and agricultural development in this area. After China's accession to the W...
