Bare sand land vegetation quick recovery method

Abstract

The invention discloses a bare sand land vegetation quick recovery method. The method comprises the first step of selecting seeds, the second step of preparing a tile-type vegetation bag, wherein the second step comprises the procedures of a, conducting mixed matching on multiple plant seeds according to the proportion of the degree of dominance; b, uniformly mixing organic compost and sand according to the volume ratio of 1:3, and adopting the mixture as a seed growing matrix; c; sowing seeds on the growing matrix to prepare the tile-type vegetation bag. Compared with the prior art, through a phytocoenology investigation method, diversity analysis is conducted, seed selection is conducted according to the calculation of the degree of dominance, a natural or secondary growth plant community structure in a controlled region is simulated, according to a plant community natural matching rule, seed configuration is conducted on multiple selected species according to the degree of dominance, the adaptability of the seed in a local environment is guaranteed, the seeds are not prone to death, and the vegetation recovery effect is thus not influenced. By precisely calculating the size of the vegetation bag, the vegetation bag is convenient to deliver and lay, the vegetation bag can be entirely buried by wind and sand within a short time, the water and fertilizer are retained, and the vegetation bag is quickly degraded.

Description

technical field [0001] The invention relates to a method for rapidly restoring vegetation, in particular to a method for rapidly restoring vegetation in bare sandy land. Background technique [0002] The situation of land desertification is becoming more and more serious, and there are many outstanding problems affecting the restoration of vegetation, such as high surface temperature, low organic matter content, and high surface activity in bare sandy land. Conventional sand damage control measures often use mechanical sand barriers to fix sand. Due to the lack of nutrients in the accumulated sand or improper selection of vegetation restoration seeds, it is difficult for the restored plants to adapt to the local environment and they are prone to death. The restoration effect of sand vegetation is not ideal. [0003] Compost is a kind of organic fertilizer made by using animal and plant remains and excrement containing fertilizer components, plus soil and minerals to be mixed...
