Problems solved by technology

The current methods of controlling sandy deserts are somewhat effective but still have some defects, such as the afforestation method, which takes a long period and has a low consolidation rate; the field ridge method: the grassland is often displaced by wind and sand, and the survival rate is low; And it is not easy to control on a large scale; the wind-proof sand fixation method: the cost of treatment is high, and the effect is not obvious

Embodiment 1

[0040] A dry area in Xinjiang was selected as the base, and an excavator was used to excavate the soil, and then a pit of 50m×80m×5m (length×width×height) was formed. As attached to the manual image 3 As shown, the excavated soil is screened according to the particle size, and the sand with the largest particle size is piled at the bottom of the pit with a thickness of 0.5m; then coarse sand with a thickness of 0.2m (with a particle size of 5~10cm) and fine sand with a thickness of 0.2 (with a particle size of 2~5cm), among which 1.4m thick fine sand and soil are stacked in the shallow water area, and 0.2m thick fine sand is stacked in the deep water area. Then make 3m×3m×0.1m (length×width×height) soil ridge squares in the shallow water area on the soil; make 4m×5m×0.2m (length×width×height) squares in the deep water area on the soil ) of the soil ridge grid. Then the anti-seepage layer is laid on the soil ridges in the shallow water area and the deep water area, and the a...

Embodiment 2

[0042] A semi-arid area in Gansu was selected as the base, and an excavator was used to excavate the soil, and then a pit of 35m×60m×6m was formed. As attached to the manual image 3 As shown, sieve according to the particle size of the soil, and pile the sand with the largest particle size at the bottom of the pit with a thickness of 0.5m; once again pile up coarse sand with a thickness of about 0.4m (with a particle size of 4~ 8cm) and fine sand (2-4cm in particle size) and soil with a thickness of 0.2m. Among them, 1.5m thick soil is piled up in the shallow water area, and 0.3m thick soil is piled up in the deep water area. Then make 4m×5m×0.2m (length×width×height) soil ridge squares in the shallow water area on the soil; make 4.5m×4.5m×0.3m (length×width × high) soil ridge grid. Lay the anti-seepage layer on the soil ridges in the shallow water area and the deep water area, and also lay the anti-seepage layer on the slopes in the shallow water area and the deep water a...

Abstract

The invention relates to an afforestation method applied to arid areas and semi-arid areas. The method is environmentally friendly and low in cost and is a novel plant growing method which aims to solve the technical problems of high cost and low efficiency of growing plants in a desert. The method for growing plants in the desert mainly comprises the steps of selecting an area needing afforestation, conducting digging and filling, making ridge cells, laying an impermeable layer, piling up soil, laying a water isolation film, and growing plants. According to the method, by changing the soil structure and laying the impermeable layer and the water isolation film, water is preserved in soil for plant growth. The afforestation method applied to arid areas and semi-arid areas is easy to implement and high in generalization performance.

Description

[0001] technical field [0002] The invention relates to a greening method in arid and semi-arid areas, belonging to the field of vegetation greening. Background technique [0003] Desert refers to a barren area where the ground is completely covered by sand, with very few plants, little rainfall, and dry air. The desert is also called a "sand curtain", where there is drought and water shortage, and areas with few plants. According to reports, my country is currently one of the countries most seriously endangered by desertification in the world, so the prevention and control of desertification is imminent. Most of the desertified land in China is located in the northwest step by step. How to use and control the desert in the development of the west is a major issue we face. The desert area has an extreme continental climate, and the annual precipitation is mostly below 250 mm. Some deserts even have no precipitation records for many years. Due to the low heat capacity of s...
