Construction process for water and soil conservation of silty sandy soil saline-alkali land revetment

Abstract

The invention discloses a construction process for water and soil conservation of a silty sandy soil saline-alkali land revetment. The construction process comprises the steps: S1, slope arranging isconducted, and a plurality of anchor rod holes are drilled; S2, vegetative bags are filled with crop seeds and loam; S3, the vegetative bags are stacked; S4, a net-shaped screen is laid; and S5, sprayseeding of nutritive base materials is conducted, and maintaining irrigation is conducted. The construction process has the following advantages and effects that a vegetative bag layer is laid on therevetment of saline-alkali land, the vegetative bags are fixedly connected through connecting buckle plates to be stably laid, then the crop seeds are placed into the vegetative bags, root systems penetrate through the vegetative bags to be inserted into the saline-alkali land so as to enable a slope to be more stable, and the safety and stability of the saline-alkali land revetment are guaranteed.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land transformation, in particular to a construction technique for slope protection and water and soil conservation of silty sandy saline-alkali land. Background technique [0002] In recent years, with the development of the economy and the increasingly urgent demand for land resources in urban construction, saline-alkali soil development and utilization projects have flourished. However, the characteristics of saline-alkali soil, such as high salt content, low nutrient content, and poor soil structure, seriously affect the regional agriculture and forestry. The improvement and greening of saline-alkali soil has always been an internationally recognized "worldwide problem". my country is a country with a large population, and there are 97 million hectares of saline-alkali land. Along with human activities, the harm of saline-alkali land in many lands is increasing. In today's land resources...

AI Technical Summary

Problems solved by technology

At present, a large number of saline-alkali lands are gradually transformed, which is the same as planting shallow-rooted crops. At the same time, in order to meet the water supply and drainage of saline-alkali lands, river canals are generally dug for irrigation of crops in saline-alkali lands. When encountering water and prone to water and soil loss, the inlet and outlet canals, inlet and outlet wells, and river bank slope protection will collapse, which will cause unnecessary losses
