Embodiment 1

[0056] The basin (150 cm in diameter and 90 cm in height) was filled with desert soil (taken from the Tengger Desert in Zhongwei City, Ningxia Hui Autonomous Region) with a height of 20 cm to simulate the desert soil under natural conditions.

[0057] Lay air-permeable anti-seepage sand (Beijing Renchuang Technology Group Co., Ltd., STS-303) with a thickness of 2 cm on the desert soil to form an air-permeable anti-seepage layer, and discharge water through STZ direct-reading air permeability tester and columnar plexiglass tube Test to detect the air permeability and seepage coefficient of the air-permeable anti-seepage layer. The results are shown in Table 1.

[0058] Afterwards, a planting soil layer with a thickness of 68 cm was laid on the air-permeable anti-seepage layer to form the desert planting structure A1.

Embodiment 2

[0060] Desert soil (sandy soil in Alxa Right Banner, Inner Mongolia) is filled in the pot (150 cm in diameter and 90 cm in height) to simulate the desert soil under natural conditions.

[0061] The top layer of desert soil (the depth is 50 centimeters) is removed, and the soil layer after removing the top layer of soil is carried out leveling treatment to make it form such as figure 1 For the concave pit shown, lay breathable anti-seepage sand (Beijing Renchuang Technology Group Co., Ltd., STS-303) with a thickness of 3 cm on the concave pit to form a breathable anti-seepage layer, and pass the STZ direct-reading air permeability Test instrument and columnar plexiglass tube for water discharge test to detect the air permeability and seepage coefficient of the air-permeable anti-seepage layer. The results are shown in Table 1.

[0062] Afterwards, a planting soil layer with a thickness of 47 cm was laid on the air-permeable anti-seepage layer to form the desert planting struct...

Embodiment 3

[0064] Desert soil (sandy soil in Lingwu area, Ningxia) was filled in the basin (150 cm in diameter and 90 cm in height) to simulate the desert soil under natural conditions.

[0065] The top layer of the desert soil (the depth is 60 cm) is removed, and the soil layer after the removal of the top layer of soil is carried out leveling to make it form as figure 1 As shown in the concave pit, lay breathable anti-seepage sand (Beijing Renchuang Technology Group Co., Ltd., STS-303) with a thickness of 5 cm on the concave pit to form an air-permeable anti-seepage layer, and pass the STZ direct-reading air permeability Test instrument and columnar plexiglass tube for water discharge test to detect the air permeability and seepage coefficient of the air-permeable anti-seepage layer. The results are shown in Table 1.

[0066] After that, a planting soil layer with a thickness of 55 cm was laid on the air-permeable anti-seepage layer to form the desert planting structure A3.

Abstract

The invention provides a desert planting structure, wherein the desert planting structure comprises a desert soil layer, an air-permeable impermeable layer and a planting soil layer, the air-permeable impermeable layer is positioned upon the desert soil layer, and the planting soil layer is positioned upon the air-permeable impermeable layer. The invention also provides a desert soil amendment method, wherein the method includes the following steps: arranging the air-permeable impermeable layer on the desert soil layer, and arranging the planting soil layer on the air-permeable impermeable layer. The invention also provides a planting method for desert soil, wherein the method includes the following steps: amending the desert soil, and planting plants and / or plant seeds into the amended desert soil; and the amendment method for the desert soil is the desert soil amendment method provided by the invention. The desert planting structure, the desert soil amendment method and the plantingmethod for the desert soil, which are provided by the invention, can effectively improve the growth status of plants and remarkably reduce water consumption.

Description

technical field [0001] The invention relates to a desert planting structure, and also relates to a method for improving desert soil and a planting method for desert soil. Background technique [0002] The phenomenon of desertification may be a natural phenomenon. As a natural phenomenon, desertification is caused by the movement of the earth's dry belt, and the resulting climate change leads to desertification in local areas. However, most of the causes of desertification in the world today are attributed to man-made reasons; the rapid population growth, the land where they live are over-cultivated and livestock grazing, resulting in thirsty land that is not suitable for farming. Desertification is a major threat to world agricultural development. It degrades the reproductive capacity of the land, reduces the production capacity of agriculture and animal husbandry, reduces the yield of crops, and reduces the area of ​​arable land and pasture. [0003] At present, the deser...
