Embodiment Construction

[0014] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0015] Embodiments of the present invention provide a method for improving saline-alkali land, which includes the following steps for every mu of saline-alkali land:

[0016] S101: Spread 10-50 kg of aluminum sulfate powder evenly on the soil surface;

[0017] S102: water the soil where the aluminum sulfate powder is spread, and soak for 1-72 hours;

[0018] S103: Prepare polyacrylamide with an amount of 5%-20% of the amount of aluminum sulfate into a solution with a mass concentration of no more than 0.5%;

[0019] S104: Spray the prepared solution evenly on the water layer, and continue soaking for 8-24 hours;

[0020] S105: Draining the water in the saline-alkali land;

[0021] S106: Apply organic fertilizer and biological bacterial fertilizer.

[0022] In the method for improving saline-alkali land provided...

Abstract

The invention relates to the agricultural field, in particular to an improvement method for saline-alkali soil. The improvement method for the saline-alkali soil comprises the following steps: sprinkling 10 to 50 kilograms of aluminum sulfate powders on the surface of the saline-alkali soil evenly; irrigating the soil with the aluminum sulfate powders and soaking the soil with the aluminum sulfate powders for 1 hour to 72 hours; compounding polyacrylamide with a dosage which is 5% to 20% of the dosage of the aluminum sulfate powders into a solution, wherein the mass concentration of the solution is no more than 0.5%; evenly spraying the compounded solution onto the water layer, and continuing to soak the soil with the aluminum sulfate powders for 8 hours to 24 hours; draining the water in the saline-alkali soil; and applying organic fertilizer and biological bacterial fertilizer to the saline-alkali soil. The improvement method for the saline-alkali soil can improve the sodium ions, the carbonate ions and the bicarbonate radical ions in the soil, so that the potential of hydrogen (pH) value of the solution of the soil can be reduced. The aluminum sulfate is increased, so that the soluble salts released by the soil particles are also increased, so that the salt materials in the soil can be reduced remarkably. Due to the fact that the macromolecule polyacrylamide is added, the soil can congeal into bigger particles like pea grains, so that permeability and water and fertilizer preserving capability of the soil can be improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for improving saline-alkali land. Background technique [0002] In the related art, there is a saline-alkali soil improver with aluminum sulfate as the main body, which can improve the physical and chemical indicators of saline-alkali soil, reduce the pH value of saline-alkali soil, and make the saline-alkali soil form a tiny aggregate structure. Yield has been significantly improved. [0003] The above-mentioned saline-alkali soil improvement method mainly using aluminum sulfate has the following problems: high cost, poor effect of reducing salt, and too fine soil aggregates formed. Contents of the invention [0004] The object of the present invention is to provide a method for improving saline-alkali land to solve the above-mentioned problems. [0005] Embodiments of the present invention provide a method for improving saline-alkali land, which includes the following st...
