Problems solved by technology

Key solutions: 1) The water retention problem of sandy soil. Usually, sandy soil seepage is large and it is difficult to store water; 2) Reduce evaporation. In arid and semi-arid areas, there is less precipitation, but the evaporation is large, which leads to the survival of plants. The rate is low, and vegetation recovery is difficult
This invention will adopt technical means such as setting anti-seepage film and covering film to solve the serious leakage and evaporation problems of sandy soil in arid and semi-arid areas, and improve the planting survival rate and vegetation recovery speed in these areas

specific Embodiment 1

[0047] (1) Planting in the weathered soil layer of Pisha sandstone

[0048] In order to simulate the environment in the Pisha sandstone area, a 1.2m×1.2m×1.0m planting box was made with a wooden box and filled with weathered Pisha sandstone sand. Excavate deep 70cm in sandbox, the planting hole that upper surface diameter is 85cm. Evenly install 4 overflow pipes with a diameter of 1.0cm at half the depth of the planting pit, and install 1 overflow pipe with a diameter of 0.6cm at the bottom (10cm above the bottom of the planting pit). The length of the overflow pipes is 10cm. Both ports of the overflow pipe are filled with screens.

[0049] Pisha sandstone comes from Zhungeer Banner, Inner Mongolia Autonomous Region. Pisha sandstone soil samples are weathered red sandstone with a maximum particle size of 10mm, gravel with edges and corners, and a specific gravity of 2.65 g / cm3. 70% of the Pisha sandstone soil samples have a particle size distribution of Between 0.05 and 2.0m...

specific Embodiment 2

[0055] In order to simulate the arid desert environment, a 1.5m×1.5m×1.0m sandbox was made with a wooden box and filled with river sand. Excavate deep 70cm in sandbox, the planting hole that upper surface diameter is 85cm. Install four overflow pipes with a diameter of 1.0 cm evenly at half the depth of the planting pit, and install one overflow pipe with a diameter of 0.6 cm at the bottom of the planting pit (10 cm above the bottom of the planting pit). For 10cm, the two ports of the overflow pipe are filled with strainers.

[0056] Adopt the same hydrophilic polyurethane resin as specific example 1 to spray on the bottom and side of the planting pit and quickly solidify to form an anti-seepage film. The concentration of the W-OH solution is 4.0%, and it is carried out at the bottom and the side of the planting pit with a double liquid pump. Spraying, the spraying time of each planting pit is generally within 0.5 minutes and the spraying construction can be completed. Then,...

Abstract

The invention discloses a planting structure and a planting method thereof, aiming to solve the problem of water shortage for plant growth in arid regions and guarantee good plant growth and vegetation recovery in the arid regions. The planting structure comprises a planting pit and a planting soil layer in the planting pit. An impermeable film is arranged on the surface of the planting pit. An evaporation-resisting cover film is arranged at the upper end of the planting soil layer. A cover soil layer is arranged at the upper end of the cover film. By the planting structure, permeation and evaporative loss of moisture are remarkably reduced, rainwater collection, confluence and storage into the planting pit are facilitated, the planting pit can have sufficient moisture for plants to absorb, and accordingly, survival rate of planted plants is guaranteed. The planting method is simple in technology, low in cost and obvious in effect in the acid regions, and is of great significance in improving planting survival rate of plants in the acid regions and recovering vegetation.

Description

technical field [0001] The invention relates to a plant planting structure and planting method in arid and desertified areas, and belongs to the technical field of ecological restoration in arid and desertified areas. technical background [0002] Land desertification, soil erosion and environmental degradation have become key issues affecting the sustainable development of human society. The world's terrestrial desertification area accounts for about 30% of the total land area. exacerbated. my country is one of the countries with severe desertification and soil erosion in the world. At present, deserts, Gobi and sandy lands total 1.653 million square kilometers, involving 18 provinces (regions) and 471 counties, accounting for about 17% of the country's land area. Land desertification has not only greatly eroded land resources, further shrinking valuable arable land and pastures, but also brought serious environmental problems, such as the sandstorms that have been raging ...
