Salinized soil conditioner and salinized soil improvement method

Abstract

The invention provides a salinized soil conditioner and a salinized soil improvement method. The salinized soil conditioner is prepared by mixing the following components in parts by weight: 50-70% of a biomass matrix, 10-15% of plant ash, 5-10% of carbohydrates, 5-10% of gypsum, 6-8% of calcium humate and 1-3% of a microbial culture solution, wherein the carbohydrates comprise chitosan, chitin, glucose, cellulose and peracetylglucose, the mass ratio of all the components in the carbohydrates is (1-3):(1-3):(3-5):(2-4):(2-3), the biomass matrix is specifically formed by mixing and fermenting a plant matrix and an excrement matrix doped with fermentation liquor for 3-5 days, the plant matrix is specifically crop straw, the excrement matrix is specifically fresh excreta of cattle or sheep, and the mixing ratio of the plant matrix to the excrement matrix to the fermentation liquor is 3:4:3. According to the invention, natural metabolism of microorganisms is utilized to enhance improvement on the saline-alkaline property of the land and improve the tolerance of crops to the saline-alkaline property of the land at the same time.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a saline soil improver and a method for improving saline soil. Background technique [0002] There are 99.13 million hectares of saline-alkali land in China. Plants in severe saline-alkali soil areas can hardly survive, especially in the arid areas in the north. Therefore, the improvement and utilization of saline-alkali soil must invest a certain amount of human, material and financial resources, which is very necessary for our country with only 1.4 mu of cultivated land per capita. [0003] Saline-alkali soil, also called saline soil, refers to the land containing excessive soluble salts in the soil, including two types of soil with different properties: saline soil and alkaline soil. The so-called saline soil mainly refers to the soil containing excessive water-soluble salt in the soil, which is mostly neutral salt, showing alkaline reaction, and the pH value is betw...

Problems solved by technology

[0005] The existing soil improvement methods mostly use soil improvers to improve the soil, but the existing soil improvers mostly use chemical products to change the soil pH, which greatly destroys the microbial ecology in the soil while improving, resulting in saline-alkali soil It is easy to reverse salt, the continuous effect of improvement is poor, and the actual use efficiency is low
