Embodiment Construction

[0022] The present invention will be further described below in conjunction with the examples.

[0023] A saline-alkali land improvement method, including water conservancy improvement, chemical improvement, physical improvement and cultivation improvement;

[0024] The water improvement includes:

[0025] Drainage method: dig a drainage ditch on the low-lying saline-alkali land, and use the drainage ditch for drainage to take away part of the salt in the land;

[0026] Irrigation and salt washing method: According to the law of "salt comes with water, salt goes with water", irrigate and form a certain depth of water layer to fully dissolve the salt in the soil, and then drain the dissolved salt from the drainage ditch to reduce the soil the salt content;

[0027] Rice planting method: It is also an effective improvement measure to grow rice in saline-alkali land with sufficient water, because after rice is planted. By flooding and draining water for a long time, the salt i...

Abstract

The invention discloses a saline-alkali soil improvement method which comprises water conservancy improvement, chemical improvement, physical improvement and tillage improvement. The water conservancy improvement comprises a drainage method; an irrigation salt leaching method; the invention relates to the technical field of saline-alkali soil improvement, in particular to a rice planting method, which relates to the technical field of saline-alkali soil improvement, and has the beneficial effects that various improvement methods are combined, so that the salt content of soil can be effectively reduced, the soil can be loosened, the physical properties of saline-alkali soil can be improved, crop root systems are developed, the stress resistance and disease resistance are improved, saline-alkali sprinkling is avoided, and saline-alkali harm is reduced. The method promotes the development of agriculture, and has extremely important practical significance for sustainable and healthy development of rural economy, land management, ecological environmental protection and the like in China, especially in inland arid agricultural irrigation areas.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a saline-alkali land improvement method. Background technique [0002] Saline-alkali land refers to a type of soil in which the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which about 34.6 million hectares of saline-alkali land in my country, 7.6 million hectares of arable land is salinized, and nearly 1 / 5 of arable land is salinized. Due to the accumulation of a large amount of salt in the soil, the saline-alkali land causes a series of deterioration of soil physical properties: the structure is sticky, the land is impermeable or poorly ventilated, the soil temperature rises slowly, the microbial activity in the soil is poor, the permeability coefficient is low, and the capillary action is strong. Evapor...
