Abstract

The invention provides a method for improving moderately-severely hardened saline-alkali land. The method includes the following steps that 1, biological amendment is applied to the moderately-severely hardened saline-alkali land, and rotary tillage and deep plowing are conducted after application of the biological amendment; 2, land preparation is conducted on the land obtained after rotary tillage and deep plowing are conducted, furrows are arranged, and the peripheries of the furrows are provided with drainage ditches communicated with the furrows; 3, sapling container bags are arranged on the formed furrows, and pinus sylvestris ssp.kulendensis is planted in each sapling container bag. By means of the method, the land utilization rate and land yield can be raised, and saline alkali of soil and the distribution range of plant root systems are improved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a method for improving moderately and severely compacted saline-alkali land. Background technique [0002] At present, soil salinization mainly occurs in arid and semi-arid areas. Due to flood irrigation and only irrigation without drainage, the groundwater level rises or the salt in the bottom soil or groundwater rises to the surface with capillary water. After the water evaporates, the salt accumulates in the In the surface soil, when the soil salt content is too high (more than 0.3%), the formation of saline-alkali disasters. In recent years, the problem of soil salinization is one of the most serious environmental problems in the world. Due to human development and utilization of large areas of land, new secondary salinization is gradually generated, which accelerates the process of soil salinization. The development and utilization of moderately and severely compac...
