Problems solved by technology

A multifunctional combined ecological slope protection base material (CN104878765A) proposes to use sandy soil, cement, organic materials, polypropylene fiber, fertilizer, and soil activated bacteria as the base material, but the base material has poor thermal insulation effect
These methods are limited to the restoration of grasslands, and no restoration methods for shrubs such as alpine rhododendrons have been proposed. Therefore, it is very necessary to find a method that can effectively restore shrub vegetation in high-altitude ecologically fragile areas.

Embodiment 1

[0030] A method for restoring vegetation in high-altitude ecologically fragile areas, comprising the following steps:

[0031] S1. Transplant appropriate amount of Alpine Rhododendron from an area with an altitude of 4500-4700m to a place with an altitude of 3500-3700m, and plant it under the conditions of a greenhouse with a substrate moisture content of 55%, relative air humidity of 80%, and a temperature of 22°C. After the plant survived, cut semi-lignified branches with a new diameter of 0.6-0.7 cm from the well-growing female parent material as the cutting material. Keep 1 complete leaf on the top, keep the terminal bud, cuttings have 2 nodes, cuttings with a length of 5cm, trim the lower end into a horseshoe shape, and finally insert into the cutting medium with pH=4.5 until the cuttings survive and take root;

[0032] S2. Then transplant the surviving and rooted cuttings in step (1) to the substrate with outdoor tailings, cow dung, highland barley stalks, pellets, and p...

Embodiment 2

[0035] A method for restoring vegetation in high-altitude ecologically fragile areas, comprising the following steps:

[0036] S1. Transplant appropriate amount of Alpine Rhododendron from an area with an altitude of 4500-4700m to a place with an altitude of 3500-3700m, and plant it under the conditions of a greenhouse with a substrate moisture content of 55%, relative air humidity of 80%, and a temperature of 22°C. After the plant survived, cut semi-lignified branches with a new diameter of 0.6-0.7 cm from the well-growing female parent material as the cutting material. Keep 1 complete leaf on the top, keep the terminal bud, the cuttings have 2 nodes, the cuttings are 5cm in length, the lower end is trimmed into a horseshoe shape, and finally inserted into the cutting medium with pH=5 until the cuttings survive and take root;

[0037] S2. Then transplant the surviving and rooted cuttings in step (1) to the substrate with outdoor tailings, cow dung, highland barley stalks, pel...

Embodiment 3

[0040] A method for restoring vegetation in high-altitude ecologically fragile areas, comprising the following steps:

[0041] S1. Transplant appropriate amount of Alpine Rhododendron from an area with an altitude of 4500-4700m to a place with an altitude of 3500-3700m, and plant it under the conditions of a greenhouse with a substrate moisture content of 55%, relative air humidity of 80%, and a temperature of 22°C. After the plant survived, cut semi-lignified branches with a new diameter of 0.6-0.7 cm from the well-growing female parent material as the cutting material.

Abstract

The invention discloses a vegetation restoration method for a high-altitude ecologically fragile area, which comprises the following steps of: transplanting alpine rhododendron from a region with the altitude of about 4500 m to a greenhouse with the altitude of about 3500 m for planting, and carrying out cuttage breeding on viable plants; transplanting the plants surviving after cutting outdoors, and carrying out outdoor adaptation training on the plants in modes of artificial heat preservation, water replenishing and the like until the plants survive; and finally, transplanting the surviving plants to an area with the altitude of about 4500 m, and carrying out outdoor adaptation training on the plants again until the plants survive. The vegetation restoration method for the high-altitude ecologically fragile area is beneficial to the improvement of the vegetation coverage rate and the reduction of the harm that the ecology is difficult to restore due to artificial or natural factors; according to the method, only a small number of alpine rhododendron plants are needed for cuttage breeding, the ecology of the region cannot be affected, local cow dung and highland barley straw are selected in the heat preservation process, and the method has the advantages that the materials are convenient to take and the method is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a method for restoring vegetation in high-altitude ecological fragile areas. Background technique [0002] High-altitude ecologically fragile areas are inherently unstable, and they are a type of area that is easily damaged by external factors but difficult to recover. In the spatial pattern, the social environment is closed, highly dependent on environmental resources, in a state of natural economy for a long time, and the relationship between man and land is close but very fragile. The fragile ecological environment and low land carrying capacity make it difficult for this area to withstand large-scale human disturbance. Long-term disturbance or uncontrolled use will cause land productivity to continue to decrease. In severe cases, resource regeneration may be destroyed, which will affect the ecological environment of the area. cause permanent damage...
