Problems solved by technology

[0003] However, these methods have more or less disadvantages, such as high labor intensity and high cost
In addition, these methods can only cure the symptoms but not the root cause. The first year of land consolidation is good for planting crops, but the phenomenon of returning to salt will appear in the second year and later, and the land that has been consolidated will become saline-alkali land again.

Abstract

The invention discloses a saline-alkali soil restoration and finishing method. The saline-alkali soil restoration and finishing method comprises the steps of mechanical deep ploughing of land, upturned soil sunning, salt elimination by underground concealed pipes, further deep ploughing, upturned soil sunning after spraying of prochloraz, application of a base fertilizer and an improved compound fertilizer, film mulching, rotary tillage and the like, wherein the improved compound fertilizer is prepared from desulfurized gypsum, charcoal, zeolite, pyrite, calcium chloride, dry branch and fallenleaf powder, furfural residues, citric acid residues, ferrous acid and a microbial agent. According to the saline-alkali soil restoration and finishing method, the pH value and the salt content of the saline-alkali soil can be remarkably reduced by planting corn after the saline-alkali soil is managed, compared with a traditional soil management method, the saline-alkali soil restoration and finishing method is better in saline-alkali soil restoration and finishing effect, and experiments prove that the soil condition of the saline-alkali soil can be gradually improved after crops are plantedin successive years after the saline-alkali soil restoration and finishing method is used for saline-alkali soil restoration and finishing.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land, in particular to a land restoration and arrangement method for saline-alkali land. Background technique [0002] Land consolidation refers to the comprehensive improvement of fields, water, roads, forests, and villages by using engineering and biological measures to increase the effective cultivated land area, improve land quality and utilization efficiency, and improve production, living conditions, and ecological environment. The main contents are as follows: 1. Use engineering and biological measures to level the land, merge scattered plots, build terraces, renovate the breeding water surface, and regulate the land for rural residential areas; 2. Build roads, wells, ditches, slope protection forests and other farmland and agricultural supporting projects; 3. 1. Control desertified land, saline-alkali land, polluted land, improve soil, and restore vegetation; 4. Define land ownership...
