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

A salina land improving method includes mounting a ventilated anti-penetration aggregate layer and mounting planting soil layer on the aggregate layer. A planting method of the salina land includes planting plants and / or plant seeds in the salina land improved by the improving method. The method can efficiently prevent salinization of the surface soil to plant longer. The method does not need to use lots of freshwater to wash, hence it can efficiently reduce water consumption and increase the use range.

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.
