Method for reconstructing shoal soil mass for rice planting

Abstract

The invention discloses a method for reconstructing shoal soil mass for rice planting, comprising the following steps: leveling the surface of a shoal; irrigating the leveled surface of the shoal with mud to form a soil layer; sun-curing the soil layer, covering the soil layer with loess, and tamping to form an artificial ploughing sole layer; leveling the artificial ploughing sole layer by shoveling high spots and filling low spots; covering the leveled artificial ploughing sole layer with loess to form an artificial plough layer; finely leveling and fertilizing the artificial plough layer; irrigating, mashing and leveling the artificial plough layer to obtain a mashed layer.The artificial ploughing sole layer and the artificial plough layer are constructed for shoal soil, project quantity is reduced, soil covering thickness is decreased, physiochemical properties of shoal soil are improved, soil fertility is improved, water utilization efficiency is improved, and land desertification is inhibited.

Description

technical field [0001] The invention belongs to the technical field of land engineering, and in particular relates to a sandbar soil reconstruction method for rice planting. Background technique [0002] With the continuous increase of the population in my country and the world, on the one hand, it is necessary to protect the quantity and quality of the existing cultivated land resources; The technology of remediation and transformation of unused land needs to be studied urgently. In the areas along the Yellow River in the central and western parts of my country, especially in the eastern part of Shaanxi and western Shanxi, there are many sedimentary wandering rivers. After flood control and control in these areas, the sandbars have high sand content and poor water retention capacity. The lack of soil nutrients and other factors, crop planting effect is not good, as a kind of land resource that is difficult to use, it is often left idle, resulting in the waste of large areas ...

Problems solved by technology

In the areas along the Yellow River in the central and western parts of my country, especially in the eastern part of Shaanxi and western Shanxi, there are many sedimentary wandering rivers. After flood control and control in these areas, the sandbars have high sand content and poor water retention capacity. Due to lack of soil nutrients and other factors, the planting effect of crops is not good. As a kind of land resource that is difficult to use, it is often left idle, resulting in a large area of ​​land resource waste.
