Abstract

The invention provides a saline-alkali soil improvement method based on rice planting. The method is characterized by improving pH value of the soil through cooperation between microbial fertilizers and calcium superphosphate, supplying fertilizers to the growth of the rice, combining rice planting with the saline-alkali soil improvement, increasing the rice yield year by year and substantially completing the improvement of the saline-alkali soil after 3-5 years.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for improving saline-alkali land based on rice planting. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in my country i...
