Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the examples. In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention is described in further detail below, but the present invention is not limited to these embodiments.

[0035] In one embodiment of the present invention, there is provided a method for improving saline-alkali land, comprising the following steps:

[0036] A. Carry out deep ploughing, drying and leveling of saline-alkali land;

[0037] B. The leveled saline-alkali land will be drained through a dark pipe;

[0038] C. After the dark pipes are laid, the saline-alkali soil is irrigated;

[0039] D. Apply soil conditioner to the treated saline-alkali land.

[0040] The steps A-D are preferably carried out once a year, and are carried out continuously for 1 to 3 years.

[0041] The deep ploughing in the step A may further include: subsoil ploughing a...

Abstract

The invention discloses a method for improving saline-alkali land. The method includes the steps of A, subjecting the saline-alkali land to deep ploughing, upturned-soil drying and leveling; B, subjecting the leveled saline-alkali land to salt elimination with underground pipes; C, after the underground pipes are laid, irrigating the saline-alkali land; D, applying a soil improver to the saline-alkali land after treatment. The steps A and D are performed once a year for 1-3 years continuously; with the method, soil salinity in the saline-alkali land can be reduced, soil nutrient is increased,and purposes of improving soil salinization, increasing grain output, enlarging vegetation coverage, alleviating ecological and environmental degradation and the like efficiently are achieved; the method is highly targeted, remarkable in effect and capable of being applied on a large scale.

Description

technical field [0001] The invention relates to the technical field of soil land improvement, in particular to a method for rapidly improving saline-alkali land. Background technique [0002] my country is one of the countries with more serious salinization hazards, and there are about 27 million m2 of saline-alkali land in the country. 2 , of which 7.7 million m 2 The above are distributed in farmland, accounting for about 7% of the cultivated land area. For arid areas, more than 1 / 3 of the soil belongs to the low and medium fields caused by salinization. Improving saline-alkali land and preventing secondary salinization, as well as maintaining and improving land productivity are important elements for maintaining land productivity in arid areas and for sustainable agricultural development. Because soil salinization directly affects soil structure, water and air conduction, water supply and fertilizer supply capacity, as well as plant emergence and growth process, scholar...
