Description

technical field

[0001] The invention belongs to the field of soil improvers, and in particular relates to a method for preparing and applying a soil improver for saline-alkali land. Background technique

[0002] The formation of soil salinization is mainly the result of the combined effects of climate, soil, water, topography and human activities. Salinized soil has a high pH value, poor air permeability and water permeability, easy to harden the surface, low nutrients and rich in harmful salts Features. Most plants are difficult to survive in saline-alkali soil, and the effective improvement of saline-alkali soil is of great benefit to the development of agriculture and animal husbandry and the improvement of the ecological environment.

[0003] The existing technologies on saline-alkali land improvement at home and abroad mainly include: physical improvement technology, chemical improvement technology, biological improvement technology and water conservancy and drainage e...
