Method for preventing salt accumulation on saline-alkali soil surface

Abstract

The invention discloses a method for preventing salt accumulation on the saline-alkali soil surface. The method comprises that straw mats are embedded in the soil body of the saline-alkali soil by layering. The provided method can prevent salt accumulation in surface of the saline-alkali soil, improve a function of water and gas heat transportation of the soil body, can also increase the content of soil organic matter and mineral element, and has the advantages of being green and environmentally friendly, and having no secondary pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of land management and agricultural utilization, and in particular relates to a method for preventing surface salt accumulation in saline-alkali land. Background technique [0002] The alias of straw curtain is grass thatch, which is made of rice, wheat and other straw as raw materials through a simple straw curtain machine. The main purpose of the straw curtain is on the greenhouse, keeping warm in the winter of the planting greenhouse, shading the breeding greenhouse, etc. As a mulch, straw curtains are easily aged after years of exposure to the sun and rain, and become one of the main agricultural wastes that affect the rural environment. Therefore, it is of great significance to recycle the aged and discarded straw mats, which can improve the utilization efficiency of crop straw resources and simultaneously improve the triple benefits of rural society, economy and environment.
