According to the topographic information and the soil characteristics, a proper planting mode, such as artificial transplanting or direct sowing, is selected to ensure the maximization of the re-greening effect.
When the re-greening area is determined, factors such as water source supply, soil regulation, plant adaptability and the like are considered, and the area which has natural advantages and has re-greening potential is selected.
Sufficient moisture required for vegetation growth can be ensured by selecting an area with a water supply. The water resources are relatively deficient in the high-cold high-altitude areas, so that the areas with rich water sources and good hydrologic conditions are selected for re-greening, plant growth and ecological system recovery are facilitated, and the areas with good soil conditions are selected for re-greening according to factors such as soil texture, nutrient content and water retention capacity. The high-quality soil is favorable for providing nutrients and moisture required by plant growth, improving the soil structure, increasing the water retention capacity and erosion resistance of the soil, and improving the survival rate and the growth and development of plants by selecting plant species suitable for local environmental conditions for re-greening. The high altitude area has cold climate and low air temperature, and the plant needs to have the characteristics of cold resistance and adaptation to cold environment, so that the species with natural advantages and adaptation capability are selected, and the success rate of the re-greening can be increased.
When plants are selected and grown, plant species with strong adaptability in local or similar ecological areas, such as mountain tree species (pine, spruce, korean pine and the like) and herbaceous plants (mountain meadow plants) are selected, a seedling culture base is established in the local or similar areas, and proper seedling growing is performed, so that the survival rate and adaptability of the plants are improved.
By selecting plant species suitable for the place or similar ecological environment, the environment adaptation capacity of the plant species can be improved, the risk of introduction and cultivation is reduced, and the survival rate of the plant is increased. The plants are adapted and grown in similar environments, are easier to adapt to the climate, soil and other ecological conditions of the target area, improve the success rate of the re-greening project, and help to restore the functions and balance of the local ecological system by selecting proper plant species in the local or similar ecological area for re-greening. The plant species usually have better interaction relation with local animal and plant, soil, hydrology and other environmental factors, can promote the restoration of local plant communities and the reconstruction of an ecological system, and can improve the adaptability and the growth potential of plants by establishing a seedling cultivation base in a local or similar area to carry out adaptive seedling cultivation. The seedling cultivation base can provide a growth environment similar to a target area, and appropriate cultivation management measures are carried out, so that stronger and more adaptive seedlings are cultivated, the survival rate of the seedlings in a field re-greening project is increased, and the plant species in a local or similar ecological area are selected for re-greening, so that the protection and promotion of local biodiversity are facilitated. These local species often build complex interdependencies with the local animals and plants, and selection of the local plant species for re-greening can maintain and re-establish this biodiversity and contribute to the stability and sustainability of the local ecosystem.
In the preparation and recovery technology selection, when vegetation belongs to tree species, a manual transplanting method is adopted, seedlings with good growth vigor and high adaptability are selected for transplanting, when vegetation belongs to herbaceous plants, a direct sowing mode is adopted, soil improvement measures are combined, and suitable grass species are selected for large-area sowing.
Through adopting the mode of artificial transplanting tree species, can improve growth vigor and adaptability, through selecting the tree species seedling that possesses good growth vigor and higher adaptability to transplant, can ensure that trees can grow flourishing in new ecological environment to adapt to climate, soil and other ecological conditions in place, and accelerate forestation effect, through artificial transplanting, can introduce mature trees in the target area in the shorter time, improve forestation effect and recovery rate. This helps to establish vegetation coverage fast, prevents soil erosion, protects water sources and biological habitats etc., and can achieve large-area herbal plant sowing when the mode of direct herbal plant sowing is adopted. This helps to quickly form a blanket, reduce the risk of bare soil, prevent water and soil loss and soil erosion, improve soil quality, promote vegetation recovery, and provide habitat and food source for local wild animals by large-area sowing of herbaceous plants. This has important significance for restoring ecological balance, enhancing biodiversity and protecting wild animals and plants.
When the soil is improved, firstly, proper soil improvement measures are adopted according to the soil analysis result, the soil quality and the water retention capacity are improved, and organic fertilizer and proper inorganic fertilizer are properly applied to improve the soil nutrient content, and meanwhile, the water retention and soil moisture preservation treatment, such as covering of water retention materials, water diversion channels and the like, is carried out, so that the water evaporation and the soil erosion are reduced.
The soil improvement measures can improve the physical, chemical and biological properties of the soil and improve the fertility and the air permeability of the soil. By adding organic substances, improving the soil structure and increasing the microbial activity of the soil, the water holding capacity and the fertilizer retaining capacity of the soil can be increased, a proper growth environment is provided, the development of plant root systems and nutrient absorption are promoted, the water holding capacity of the soil can be increased by soil improvement, and the evaporation and the excretion of water are reduced. By improving the soil structure, the porosity and water holding capacity of the soil can be increased, and the adsorption and retention capacity of the soil to moisture can be increased. This helps to provide moisture required for plant growth, and reduces waste and loss of moisture, improves water resource utilization efficiency, and soil improvement can improve nutrient content and supply capacity of soil. By applying the organic fertilizer and an appropriate amount of inorganic fertilizer, the nutrient content in the soil can be increased, and nutrient elements required by plants can be provided. This helps promote plant growth and development, increases yield and quality, and soil improvement measures can also reduce wind erosion and water erosion of the soil. By means of measures such as covering water retention materials, water diversion channels and the like, the water flow speed can be slowed down, water flow is prevented from scouring the soil surface, and the risk of water and soil loss is reduced. Meanwhile, the erosion and loss of wind erosion to the soil can be reduced by increasing the water holding capacity and wind resistance of the soil.
During plant protection and management, pruning and weeding are needed regularly, healthy growth of plants and stability of communities are maintained, pest control is noted, targeted measures are taken, influence of pest on the re-greening work is avoided, and meanwhile, biodiversity maintenance measures are introduced, natural ecological balance is promoted, and stability of vegetation is improved.
The growth form of the plants can be controlled by regular pruning and weeding, the growth of the side branches is promoted, and the plants keep healthy and have good appearance. Pruning can also promote branching and photosynthesis of plants, improve light energy utilization efficiency, increase yield and quality, reduce competition of weeds, create good growth environment and maintain stability and balance of plant communities through timely pruning and weeding.
