Problems solved by technology

Soil salinization prevents large areas of land from being effectively used, seriously affecting agricultural production and improving farmers' living standards
[0003] At present, in many saline-alkaline soil improvement measures, water conservancy engineering measures, agricultural cultivation measures, halophytes, chemical modifiers and other methods have been widely used, but the effect is not satisfactory
Although chemical improvement measures can quickly change the soil structure, it may also cause secondary pollution; agricultural measures need to consume a lot of manpower, material and financial resources; biological improvement measures are slow to take effect and have a long cycle

Abstract

The invention relates to the technical field of saline-alkali land improvement, in particular to a comprehensive treatment method for a saline-alkali land. The method consists of the following steps that 1, the saline-alkali land is deep ploughed and tilled loosely, an rice straw interlayer is laid and the surface is leveled, wherein the ploughing depth is 25-30 cm; 2, irrigation and salt washingare performed three times, wherein the water consumption is 60-160 m<3> per mu at a time, and the total water consumption is 300-400 m<3>; 3, a microbial organic fertilizer is applied to the saline-alkali land, tilling and leveling are conducted again; 4, salt-tolerant alkali-tolerant rice is planted for crop rotation with green manure plants. The method can improve the physical structure of soil,reduce the evaporation amount of water in the soil of the saline-alkali land, enhance the water-holding capacity of the soil, increase the content of organic matter, reduce the disasters of crop diseases and insects, increase the yield of crops, improve the economic benefits of the saline-alkali land and reduce the degree of soil salinization.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a comprehensive treatment method for saline-alkali land. Background technique [0002] Saline-alkali land is the general term for all kinds of saline soil, alkaline soil and salinized and alkalized soil. According to the amount of saline-alkali content in the soil, it can generally be divided into three types: mild, moderate and severe saline-alkali land. As an important land resource, soil Salinization has seriously affected the regional ecological environment and food production. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area reaches 955 million hm 2 , while the total area of ​​saline-alkali land in my country is about 99.14 million hm 2 , ranking third in the world. Saline-alkali soil is mainly characterized by stickiness when wet and poor air permeability; hard when dry and poor water permeability. In sever...
