Problems solved by technology

Among many saline-alkali soil improvement measures, water conservancy engineering measures, agricultural cultivation measures, chemical amendments and other methods have been widely used, but the effect is not ideal
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 resources and financial resources

Abstract

The invention relates to the technical field of soil improvement, in particular to a method for improving saline-alkali land by using red clover and sandy dates. The invention comprises the following steps: (1) deeply plowing saline-alkali land, applying decomposed organic fertilizer as base fertilizer; (2) sowing red clover seeds, and inoculating rhizobia and arbuscular mycorrhizal fungi; (3) harvesting red clover Remove its aerial parts and tap roots, ditch the soil surface, and sow the seeds of Eleuthero jujube. After using the improvement method of the present invention, the salinity and pH of saline-alkali land all have obvious decline, soil nutrients such as organic matter, nitrogen, phosphorus and potassium content etc. all have risen, and the growth of red clover and sandy date is better, improving saline-alkali land while improving The economic value of saline-alkali land has certain practical significance in production.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving saline-alkali land by using red clover and sandy dates. 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. ...
