Embodiment 1

[0037] Fill the saline-alkali soil in the flowerpot (40 centimeters in diameter and 90 centimeters in height) to simulate the saline-alkali land.

[0038] Remove the surface soil of the saline-alkali land (the depth is 18 cm), and lay breathable anti-seepage sand (Beijing Renchuang Technology Group Co., Ltd., STS-303) with a thickness of 2 cm on the saline-alkali land from which the surface soil has been removed to form air-permeable anti-seepage bone. material layer, laying a planting soil layer with a thickness of 16 cm on the air-permeable anti-seepage aggregate layer.

Embodiment 2

[0040] Fill the saline-alkali soil in the flowerpot (40 centimeters in diameter and 90 centimeters in height) to simulate the saline-alkali land.

[0041] Remove the surface soil of the saline-alkali land (the depth is 40 cm), level the soil layer after removing the surface soil, and lay breathable anti-seepage sand with a thickness of 3 cm on the leveled soil layer (Beijing Renchuang Technology Group Co., Ltd. company, STS-303) to form an air-permeable anti-seepage aggregate layer, and a planting soil layer with a thickness of 37 cm is laid on the air-permeable anti-seepage aggregate layer.

Embodiment 3

[0043] Fill the saline-alkali soil in the flowerpot (40 centimeters in diameter and 90 centimeters in height) to simulate the saline-alkali land.

[0044] Remove the surface soil of the saline-alkali land (the depth is 50 cm), level the soil layer after removing the surface soil, and lay breathable anti-seepage sand with a thickness of 4 cm on the leveled soil layer (Beijing Renchuang Technology Group Co., Ltd. company, STS-303) to form an air-permeable anti-seepage aggregate layer, and a planting soil layer with a thickness of 46 cm is laid on the air-permeable anti-seepage aggregate layer.

Abstract

The invention provides a method for improving saline-alkali soil. The method comprises the following steps of: removing topsoil of the saline-alkali soil, setting an air-permeable anti-seepage aggregate layer on the saline-alkali soil of which the topsoil is removed, and setting a planting soil layer on the air-permeable anti-seepage aggregate layer. The invention also provides a planting method for the saline-alkali soil. The method comprises the following step of: planting plants and/or plant seeds in improved saline-alkali soil, wherein the improved saline-alkali soil is treated by the method for improving the saline-alkali soil. The method for improving the saline-alkali soil and the planting method for the saline-alkali soil can effectively prevent the planting soil layer of the surface layer from being salinized, so that the planting soil layer is suitable for plantation for a long time; moreover, by the method for improving the saline-alkali soil, a large amount of fresh water resources are not needed for washing, so that the water consumption is effectively reduced and the using range of the method is expanded.

Description

technical field [0001] The invention relates to a method for improving saline-alkali land and a planting method for saline-alkali land. Background technique [0002] At present, the treatment methods for saline-alkali land at home and abroad generally include salt discharge method and salt pressure method, etc., but they all have many shortcomings. The salinity reduction method is to use natural precipitation or artificial flood irrigation to promote part of the salinity to penetrate downward along the pores and cracks of the soil, and bring the salinity of the surface soil to the bottom layer with the water. Although the above method can reduce the salt content of the saline-alkali surface layer, it cannot be maintained for a long time and requires a large amount of water. [0003] Therefore, there is an urgent need to develop a method and a planting method for saline-alkali land that consume less water and can effectively improve saline-alkali land for a long time.
