Embodiment Construction

[0010] The soil improvement method of saline land with thick clay and sand layer is to dig deep into the soil profile to determine the depth of the thickest sand layer; holes; improve its physical and chemical properties according to soil conditions. Thick clay sand layer saline land soil improvement method is to adopt the following specific steps to realize: 1, dig deep soil profile 1 (or 1.6, or 2.1, or 2.9, or 3) meters, find out the thickest sand layer; 2 1. Dig several buried pipe trenches side by side, and lay the pipeline obliquely in the thickest sand layer of each buried pipe trench. There are through holes on the cylindrical surface of the pipes, and the through holes are covered with filter cloth; 3. According to the soil conditions , the soil dominated by Artemisia saline can be reduced by well irrigation and drainage; the cracked soil dominated by no vegetation or sparse reed vegetation can be chemically improved to improve soil physical and chemical properties; 4...

Abstract

The invention relates to a method for improving soil, in particular to a method for improving thick-clay sand-layered soil in salinate fields, solving the problem that the traditional method for improving the thick-clay sand-layered soil in salinate fields can not achieve the purpose of treatment fundamentally. The method comprises the following steps: determining the depth of a thickest sand inclusion layer by deeply digging a soil profile; then digging a pipe-embedding trench and laying a pipe in the thickest sand inclusion layer; arranging a through hole on a cylindrical surface of the pipe; and improving the physical property of the soil according to the soil condition. The step of laying the pipe in the sand inclusion layer is added on the basis of the traditional method for improving the soil, therefore, the invention solves the problem that the traditional method for improving the soil can not fundamentally achieve the purpose of treatment, and effectively saves the soil resources in China; and the method has the advantages of low cost, convenient operation, higher practicability and the like.

Description

technical field [0001] The invention relates to a method for improving soil, in particular to a method for improving soil in saline land, in particular to a method for improving soil in saline land with a thick clay-sand layer. Background technique [0002] my country is a large country with a population of 1.2 billion, and its per capita resources, whether land or water, are lower than the world average. However, we are still facing an irreversible situation of arable land reduction and population increase. The protection and rational development of water and soil resources are obvious. It is a career that benefits the present and contributes to the future. So far, about 80% of the saline land in our country has not been developed and utilized as a soil resource, which has great potential. [0003] Saline land is the soil that is easier to improve, and it is the reserve resource of cultivated soil. The saline land far away from the river beach has gradually formed one or m...
