Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] combine figure 1 , the method of controlling and improving saline-alkali land, the specific improvement process is as follows:

[0026] (1) Plow the saline-alkali land first, and then flatten the plowed saline-alkali soil evenly to obtain a saline-alkali soil layer 1 , and set a salt pool 4 on the saline-alkali soil layer 1 . The preferred thickness of the saline-alkali soil layer 1 of the present invention is more than 0.5 meter, certainly, the bigger the better of the thickness of the saline-alkali soil layer 1, the purpose of plowing the saline-alkali soil is to destroy its original capillary action that has formed, and reduce the ground salt etc. of the lower layer as much as possible The rate at which chemicals move up.

[0027] (2) Laying the first salt barrier layer 2 on the surface of the saline-alkali soil layer 1 . The first salt barrier layer 2 is ...

Abstract

The invention relates to a method for controlling and improving saline-alkali land. (1) plowing the saline-alkali land first, then flattening the plowed saline-alkali soil evenly to obtain a saline-alkali soil layer, and setting a salt pond on the saline-alkali soil layer; (2) laying the saline-alkali soil layer Laying the first salt barrier layer on the surface; (3) laying several main seepage pipes in parallel on the surface of the first salt barrier layer, the main seepage pipes are kept inclined, and the lower end of the main seepage pipes is connected to the salt pool; (4) The main seepage pipe is covered on the second salt-separating layer; (5) Lay guest soil layer on the second salt-separating layer. Compared with the prior art, the method of the invention has the advantages of low cost, simple process, strong operability and the like.

Description

technical field [0001] The invention relates to a method for controlling and improving saline-alkali land. Background technique [0002] Due to the unreasonable activities of human beings and the continuous deterioration of the environment, the degree of salinization of the land is increasing, which not only greatly destroys the ecological environment, but also leads to the continuous reduction of available land, making the improvement and management of saline-alkali land a very important issue. [0003] For the transformation of saline-alkali land, humans have done a lot of meaningful exploration and research, mainly in the following ways: 1. Chemical improvement method, that is, adding a large amount of chemical substances to saline-alkali land, such as gypsum, phosphogypsum, acidic substances and water-retaining agents, etc. Chemical, to improve the active ingredients in saline-alkali land; 2. Biological methods, mainly by planting alkali-resistant plants and artificially...
