A method for rapid forestation in frontier areas of vegetation restoration on windward slopes of islands

Abstract

A method for rapidly forming forests in the frontier area of ​​vegetation restoration on windward slopes of islands, comprising the following steps: Step 1, constructing artificial wind barriers: A, installing supports; B, installing windshield nets; Step 2, constructing plant wind barriers: A, vegetation Selection; B, selection of planting site; Step 3, planting trees in the vegetation restoration area: A, regional layout; B, tree selection; C, oblique planting hole setting; D, oblique planting density; E, oblique planting; F , Vegetation planting in normal planting area. The present invention reduces the wind speed on the windward side of the island by adopting the above-mentioned combination of the artificial wind barrier and the plant wind barrier, and protects the plants in the vegetation restoration area on the leeward side of the wind barrier from the wind, reducing the invasion of wind damage and ensuring better growth of plants in the vegetation restoration area. , to increase the rate of vegetation closure and forest formation, can effectively establish a vegetation restoration area by means of oblique planting and dense planting, avoid shrubs or flags of trees caused by wind damage, and improve the restoration effect of vegetation on windward slopes of islands.

Description

technical field [0001] The invention relates to a method for planting saplings under wind-shielding conditions, in particular to a method for rapid forestation in frontal areas of vegetation restoration on windward slopes of sea islands. Background technique [0002] The island has special geographical conditions and harsh ecological environment. It is seriously affected by typhoons, droughts, and northeast monsoons, and its vegetation is poorly developed. The natural recovery period after vegetation destruction is very long, and some cannot recover naturally, causing serious ecological degradation, soil erosion, island erosion and other problems. Using artificial intervention to restore island vegetation is a key measure to curb the degradation of island vegetation and promote the restoration of island vegetation. However, due to the constraints of the natural habitat of the island, some areas are affected by northeast monsoons, typhoons, salt spray, and rainstorms. Thin, ...

AI Technical Summary

Problems solved by technology

[0004] Commonly, saplings are planted in an upright manner, which is conducive to the continued upward growth of the trunk, but among the partially dry plants affected by the northeast monsoon in winter, the proportion of upright plants withered is relatively large

On the front of the windward slope, it is difficult for the plants to grow, and the closed depression time is long, which is not conducive to the rapid forestation of plants in the vegetation restoration area, so the vegetation restoration effect on the windward slope of the island is very small.
