Abstract

The invention discloses a saline-alkali soil improving agent. The saline-alkali soil improving agent comprises, by weight, 20-30 parts of humic acid, 15-25 parts of furfural residues, 8-12 parts of fruit peel, 12-18 parts of livestock and poultry manure, 10-12 parts of attapulgite, 8-10 parts of boric acid, 6-8 parts of expired foods, 8-10 parts of drug dregs, 6-9 parts of diammonium phosphate, 8-12 parts of potassium sulfate, 0.2-0.3 parts of copper sulfate, 0.1-0.5 parts of ammonium molybdate, 0.2-0.6 parts of polymaleic anhydride, 0.1-0.8 parts of aminotrimethylphosphonic acid, 0.1-0.5 parts of citric sulfonic acid, 0.7-1.3 parts of eucalyptus oil, 0.1-0.5 parts of strain powder and 1.3-1.8 parts of a silane coupling agent. The saline-alkali soil improving agent improves soil fertility,increases the granule structures in the saline-alkali soil, reduces the pH of the saline-alkali soil and effectively improves the physicochemical properties of saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a soil improver for saline-alkali land. Background technique [0002] Soil salinization, also known as soil salinization, refers to the natural geological process in which salt continuously accumulates on the soil surface to form saline-alkali soil. Saline-alkali soil is formed under certain natural conditions such as climate, terrain, land, and hydrogeology. Soil salinization is a worldwide problem. The area of ​​salinized soil in the world is about 1 billion hectares; the area of ​​saline soil in our institute is about 34.6 million hectares, and the salinization of cultivated land is 7.6 million hectares, and about 1 / 5 of the cultivated land is salinized. . [0003] The main feature of saline-alkali land is that it contains more water-soluble salt or alkaline substances. Due to the high salinity and high alkalinity, the soil humus is lost and the soil structure ...
