Intermediate zone forest layer for three-layer ecologic sand prevention and soil fixation forest belt and forest establishment method thereof

Abstract

The invention discloses an intermediate zone forest layer for a three-layer ecologic sand prevention and soil fixation forest belt and a forest establishment method thereof. The forest layer is divided into an upper layer level and a lower layer level, the first layer level is a plant layer level, the layer level body is a flat and long rectangular-ambulatory-plane-shaped forest belt formed by marshaling long-spike tamarix chinensis as main plants, 3-4 kudzu vines are cultivated nearby each main plant root at equal intervals, and middle caragana is planted outside the region 60-70 cm away fromthe main roots; the second layer level is a supply layer, the layer is arranged at the ground bottom 1.5-2 m away from the ground surface, a layer of a starch grafting sodium acrylate membrane is laid at the bottom of the supply layer, a slow release plant material layer composed of Greater Khingan coniferous forest fallen leaves is laid on the membrane, and the slow release plant material layeris mixed with starch-base mixed bacterium powder composed of Rhodomicrobium vannielii, Bacillus licheniformis, saccharomycetes and Chainia antibiotic bacteria. The layer contains multiple layer levels, has multiple ecologic environments, and is long in fertilizer enrichment period, good in sand prevention effect, high in soil solidifying force and good in economy.

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.
