Vegetation regreening method

Abstract

The invention provides a vegetation regreening method. The vegetation regreening method comprises the following steps: S1, providing and mixing short-life plant seeds and local suitable plant seeds, and the proportion of the short-life plant seeds is 5%-30%; S2, sowing the mixed seeds in a to-be-sown area according to a preset density; S3, laying a non-woven fabric in the sowing area; and S4, removing the laid non-woven fabric within 2 / 5-2 / 3 time of the growing season of the suitable plants of the planting site or before the flowering period of the used main short-life plants. The short-life plants can quickly grow by means of favorable conditions, shading protection in the seedling stage can be provided for the long-term regreening plants sown in the same period, and the quality and efficiency of regreening engineering in the alpine perturbation area are improved; and the short-life plants can play a role of pioneer plants, the adverse soil structure and texture of a disturbance area are improved through root system decomposition and / or overground organism returning to the field, and good conditions are created for long-term stable growth of main annual or perennial regreening plants.

Description

Technical field [0001] The present invention relates to the field of ecological greening techniques, and more particularly to a transplanted atrium. Background technique [0002] The growth season short cold zone vegetation growth is short-lived, low oxygen, growing period, and the ecological vegetation is very difficult to recover after disturbance. Due to the cultivation of vegetation in the cold zone disturbance area formed by the mining mining, road construction, including the recovery of natural degradation vegetation in cold, multi-use grass species, but often due to the maintenance of the seedling period, The short-term complex green effect is relatively good, long-term degradation is serious. [0003] Therefore, in the related art, the vegetation complex green method in the cold zone disturbance area has a low survival rate and the difference in complex green effect. [0004] Moreover, for ordinary herbaceous plants, early growth, leading to problems with poor recovery ef...

AI Technical Summary

Problems solved by technology

Vegetation regreening (including the recovery of naturally degraded vegetation in cold regions) in cold regions disturbed by activities such as mining and road construction often adopts the method of grass seed sowing, but often due to insufficient maintenance and protection at the seedling stage, there are The short-term regreening effect is relatively good, and the long-term degradation is serious

[0003] Therefore, in the related technology, the method of regreening the vegetation in the disturbed area in the cold region has the problems of low survival rate and poor regreening effect.

[0004] Moreover, for common herbaceous plants, the early growth is slow, leading to the problem of poor early regreening effect
