Embodiment Construction

[0038] The specific technical solutions of the present invention are described in conjunction with the examples.

[0039] A "three ten combinations" soil spraying method for vegetation restoration on high and steep slopes, comprising the following steps:

[0040] S1. Selection of tree species and collection of seeds for soil spraying test

[0041]For vegetation restoration in extremely difficult areas, the tree species must be selected according to the site conditions, not the land plots based on the afforestation task. Therefore, the selection of tree species becomes crucial, which determines the success or failure of vegetation restoration and the quality of watershed ecological restoration. The present invention is based on the principle of suitable trees in the right place, taking the Honghe dry and hot valley of Yunnan Province as the research object, according to the route Yuanjiang-Honghe-Yuanyang, mainly based on native species, investigated and collected 23 kinds of ...

Abstract

The invention provides a 'three-ten-combination' soil spray-seeding method for high and steep slope vegetation recovery. The method includes the steps of according to different microorganism combination germination species characteristics, finally screening out ten plant tree species, including two arbors, three herbaceous plants and five shrubs; meanwhile, screening out ten microorganism combinations most suitable for vegetation restoration of a high and steep slope; spraying and sowing soil with the depth of 10 cm; and adopting three layers of ecological protection which comprise a physical protection layer, an anti-corrosion protection layer and a vegetation ecological restoration protection layer. According to the 'three-ten-combination' soil spray-seeding method for high and steep slope vegetation recovery, by means of the nitrogen fixation effect of leguminous plants, a leguminous plant-non-leguminous plant combination is formed, and an arbor-shrub-herbaceous plant composition is constructed, so that conversion and circulation of soil nutrient substances are promoted, and survival and growth of germinating species are improved; and a microbial agent can promote the formation and growth of leguminous rhizobium, and the effects of different microbial agent combinations are different.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a "three ten combinations" soil spraying method for vegetation restoration on high and steep slopes. Background technique [0002] Yunnan has high mountains and steep slopes, complex geology, forming fragile ecosystems such as hot and dry valleys and karsts, and it is difficult to restore vegetation; Yunnan is rich in mineral resources and is known as the "Kingdom of Non-ferrous Metals". Road construction has a long way to go, and road construction in areas with complex topography has created many high and steep slopes. Vegetation restoration in areas such as steep mountain slopes and exposed rock walls has drawn increasing attention from all walks of life. [0003] Early research on slope treatment along the three sides (along the road, along the river, and along the lake) usually adopted the combination of natural restoration, anchor rod / anchor cable...
