A planting unit suitable for vegetation restoration in desert land

Abstract

The invention discloses a planting unit suitable for vegetation restoration in desert areas. The planting unit comprises a planter, the planter consists of two planting trays, the two planting trays are connected in an inverted manner, the center position of the interior of the planter is clamped with a plant planting ring, the bottom face of each planting tray is provided with a planting hole matching with the plant planting ring, four air-permeable holes are symmetrically arranged along the planting hole at the bottom face of the upper planting tray, the bottom face of the lower planting tray adopts a biological cloth layer, the plant planting ring is an elastic plastic circular ring with an opening at one end, a plurality of through holes are arranged at the plastic circular ring alongthe circumference direction, the interior of each through hole is provided with a plurality of water-absorbing fiber bundles in a penetrating manner, and the water-absorbing fiber bundles are connected with the plastic circular ring through a water-absorbing fiber woven net. According to the planting unit, the stable fixation of plants is realized, the germination rate and survival rate of seeds are improved, nutrient requirements in the plant growth process are ensured through combined use of the air-permeable holes, ecological cloth layers and drip irrigation belts, and nutrient loss is reduced.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a planting unit suitable for desert vegetation restoration. Background technique [0002] In recent years, with the acceleration of my country's economic and social development, the construction of highways, wind farms, etc. is increasing, and the number of exposed slopes caused by various filling, excavation, and blasting constructions is increasing; the desert land is arid and semi-arid. Under the conditions of drought, wind, little rain and loose sandy surface, the fragile ecological balance has been destroyed due to factors such as man-made and unreasonable over-intensive use of land. Phenomenon. Bare slopes and desert land have lost the soil matrix on which plants grow, so their stability is poor and soil erosion is very serious. Water and soil loss can easily lead to disasters such as landslides, landslides, and mud-rock flows. Therefore, bare hillsides and desert land...

AI Technical Summary

Problems solved by technology

Though this method can make the bare hillside be greened quickly, the problems that exist are: 1, adopt reinforced concrete to build the square grass grid, the project is large, and the cost is high; 2, in the dry season, need to often adopt spraying 3. The soil suitable for seed growth is placed in a plastic bag, and the sprayed water or rainwater tends to flow away along the surface of the plastic bag, making it difficult to penetrate into the soil. Low; 4. There is a layer of plastic film between the soil and the hillside rock formation. After the plants grow, the roots cannot go deep into the rocks. When the typhoon comes, the plants are easily uprooted and cannot play a good role in water retention and soil stabilization. Function; 5. Because the soil needs to be transported from other places, and the thickness of the soil layer of this method is generally 10-20cm, the construction cost is very high, making it difficult to popularize
