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.

Embodiment

[0065] On the basis of the above-mentioned indoor test, the following rice planting test was carried out to support the technical effect of the sandbar soil reconstruction method of the present invention. Taking a sandbank in the Longmen section of the Yellow River in Shaanxi as an example, three test areas were set up, each with an area of ​​6m×18m. The rice was planted in the designed test area according to the conventional rice planting method, and the planting method and post-management and protection in each test area were the same. The first test area is sandbar soil without soil reconstruction; the second test area is covered with 25cm loess on the sandbar soil, and the dry bulk density of the covering soil is 1.3g / cm 3 Carry out the soil reconstruction of the plow bottom layer and the plow layer on the sandbar soil in the test plot three, and the specific methods are as follows:

[0066] (1) Leveling the surface of the sandbar, the specific steps are:

[0067] (1a) O...

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 ...
