Abstract

The invention discloses a composition for improving saline-alkali soil, and belongs to the technical field of improvement of saline-alkali soil. The composition is prepared from, by weight, 40-80 parts of cyclodextrin, 40-80 parts of polylactic acid, 20-70 parts of calcium sulfate, 20-70 parts of magnesium sulfate, 10-20 parts of aluminum sulfate, 30-50 parts of ammonium sulfate, 0.5-1.5 parts ofyeast, 0.5-1.5 parts of lactic acid bacteria, 0.5-1.5 parts of acetobacter, 0.5-1.5 parts of gluconobacter, 0.5-1.5 parts of aspergillus niger, 10-30 parts of peptone and 10-30 parts of glucose. The composition rapidly adjusts the alkalinity of the saline-alkali soil by inorganic strong acid weak base salt, and the pH value of the saline-alkali soil is continuously adjusted by the action of microorganisms.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil improvement, and in particular relates to a composition for improving saline-alkali soil and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil containing high chloride or sulfate, and the soil is alkaline, while alkaline soil refers to soil containing carbonate or heavy phosphate, with a high pH value, and the soil is alkaline. Saline-alkali soil has low organic matter content, low soil fertility, poor physical and chemical properties, and many anions and cations that are harmful to crops, making it difficult for crops to promote seedlings. my country is a large agricultural country, and agricultural development is one of the important components of national economic development. Studying effective measures to control saline-alkali land, transforming saline-alk...
