Abstract

The invention provides a saline land improvement method and belongs to the technical field of saline land improvement. The saline land improvement method comprises the following steps of locally smashing straws of plants growing in a saline land and then spreading the straws on the saline land, continuing to sequentially spread a composite microbiological material for renovation and urea on the surface of the saline land spread with smashed straws, and plowing and watering the saline land spread with the smashed straws, the composite microbiological material for renovation and the urea on the surface, wherein the composite microbiological material for renovation comprises raw material components: 4-6 parts by weight of organic manure, 2-4 parts by weight of humic acid, 0.7-3 parts by weight of agricultural organic waste, 0.2-0.4 part by weight of marine organic waste, 0.01-0.02 part by weight of liquid fungicide and 0.005-0.01 part by weight of solid fungicide. The saline land improvement method has the advantages of being low in renovation cost, small in working amount, convenient to operate and free of secondary pollution.

Description

technical field

[0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a method for improving saline-alkali land. Background technique

[0002] Saline-alkali land refers to the land where the salt contained in the soil affects the normal growth of crops. In areas with severe saline-alkali soil, plants can hardly survive. In the process of saline-alkali utilization, it can be divided into mild saline-alkali land, moderate saline-alkali land and severe saline-alkali land.

[0003] In mild saline-alkali land, the salt content is below 0.3%, the emergence rate is 70%-80%, and the pH is about 7.1-8.5; in severe saline-alkaline land, the salt content exceeds 0.6%, the emergence rate is less than 50%, and the pH is above 9.5; in moderate saline-alkali land The salt content is 0.3-0.6%, the emergence rate is 50%-70%, and the pH is about 8.5-9.5.

[0004] The main reasons for the formation of saline-alkali land are:

[0005] Climate...
