Embodiment 1

[0029] A method for controlling saline-alkali land by combining engineering and chemical improvement on coastal saline-alkali land, the steps are as follows:

[0030] (1) Treatment before laying of hidden pipes

[0031] Remove weeds and rocks on the original landform to ensure that the land has a foundation for farmland planting; level the land to ensure that engineering equipment can enter the field for operations;

[0032] (2) Laying of hidden pipes

[0033] Before laying the hidden pipe, re-measure the elevation point to ensure that the value is correct, lay the line according to the preset hidden pipe, and insert the benchmark at the beginning and end. Carry out laser measurement according to the slope calculated according to the design to ensure the slope of the buried pipe, use an excavator to excavate the trench for the buried pipe, fill it according to the selected filter material of the hidden pipe, and then lay the hidden pipe. After the laying is completed, backfi...

Abstract

The invention discloses a method for treating saline-alkali soil of coastal saline-alkali soil through the combination of engineering and chemical improvement, and belongs to the technical field of saline-alkali soil improvement. The method for treating the saline-alkali soil of the coastal saline-alkali soil through the combination of engineering and chemical improvement comprises the steps of (1) concealed conduit laying pretreatment, (2) concealed conduit laying, (3) soil conditioner application, (4) crop planting and the like. By adopting the method for treating the saline-alkali soil through the combination of engineering and chemical improvement, when rice is planted on the coastal saline-alkali soil, on the one hand, a remarkable salt reduction effect is achieved on the saline-alkali soil through engineering measures, and on the other hand, the physical and chemical properties of the soil can be adjusted through matching of a soil conditioner, so that the overall improvement effect on the soil is further achieved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a method for controlling saline-alkali land by combining engineering and chemical improvement on coastal saline-alkali land. Background technique [0002] Soil salinization is a prominent ecological and environmental problem in dry farming areas in the world. China has a large area of ​​saline soil, which is widely distributed and of various types. The total area of ​​modern salinized soil, residual salinized soil, and potential salinized soil is 99.133 million hectares, which is almost equal to the area of ​​cultivated land in my country. As the area of ​​cultivated land continues to shrink, saline-alkali land, as an important land resource in my country, has the potential to use current new products and technologies to make reasonable and scientific improvements, thereby opening up a new direction for my country's agricultural development. ...
