A middle zone forest layer of a three-layer ecological sand-preventing and soil-fixing forest belt and its forestation method

Abstract

The invention discloses a forest layer in the middle zone of a three-layer ecological sand-preventing and soil-fixing forest belt and a forest forming method thereof. The forest layer is divided into upper and lower levels, the first level is the plant level, and the main body of the level is long spike Tamarix is ​​a flat and long "back"-shaped forest belt composed of main plants. Each main plant has 3-4 kudzu vines planted equidistantly beside the root, and Caragana in the middle is planted outside the area 60cm-70cm away from the main plant; The second level is the supply layer, which is set on the ground 1.5m-2m above the ground, and a layer of starch-grafted sodium acrylate film is laid on the bottom of the supply layer, and a slow-release plant material composed of fallen leaves of the Daxinganling coniferous forest is laid on the film Layer, the slow-release plant material layer is mixed with Rhodobacter vaninii: Bacillus licheniformis: Yeast: Antibiotic Chinella starch-based mixed bacterial powder. The invention has multiple layers, multiple ecological environments, long fertilization period, good sand control effect, strong soil fixation ability and good economical efficiency.

Description

technical field [0001] The invention relates to the technical field of ecological forestry, in particular to a forest layer in the middle zone of a three-layer ecological sand-preventing and soil-fixing forest belt and a forest forming method thereof. Background technique [0002] Desertification prevention and control is a long-term undertaking. my country now invests a lot of manpower and material resources in sand prevention and control. It costs a lot of money every year to plant Haloxylon, salix and other plants, especially in areas with severe desertification, such as the desert edge in northwestern my country. It is dominated by shrubs, the effect of sand control is slow, the plant level is relatively simple, and there are basically no plant resources available to humans, and it is impossible to rely on sand to eat sand. There is no doubt that this will not lead to long-term stability. The most fundamental and best way is to rely on sand to eat sand. [0003] But the c...

Problems solved by technology

Although the timing is good and the hardware is complete, the most fundamental problem is that there is no supporting ecological planting system in the existing technology, and it is still a bottomless pit of money for sand prevention and soil stabilization.
