Stress-resistant plant cultivation method and ecological restoration method in alpine region

Abstract

The invention relates to the technical field of plant cultivation, in particular to a stress-resistant plant cultivation method and ecological restoration method in an alpine region. The method comprises the following specific steps: preparation of a field planting bed, acquisition of plants, selection of finished seedlings and field planting of nursery stocks. The soil fixation amount of cultivated plants is increased by about 75%, soil can be fixed, water and soil loss is reduced, the increment of the dry weight of the plants is 42%, the increment of the root length is 32%, the increment of the plant height is 42%, plant growth-promoting bacteria are used for promoting plant growth, the heavy metal content of the plants is increased, and the plant extraction and restoration efficiency is enhanced. Through inoculation of an ecological restoration agent and inoculation of a strain W33, plant root systems are developed, the soil fixation amount is remarkably increased by 98%, water and soil conservation of tailings wasteland is facilitated, a bacterial W33 strain can produce siderophore at high yield, the stress resistance of drought resistance, cold resistance, waterlogging resistance, salt and alkali resistance and disease and pest resistance of plants can be improved, a phosphate solubilizing characteristic is achieved, and plant growth promotion is facilitated.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating stress-resistant plants in alpine regions and an ecological restoration method. Background technique [0002] The desertification environment in the Muli mining area of ​​Qinghai is harsh, and the air is filled with dust. In addition, Qinghai is high in altitude and widely distributed in mountains and deserts, and the air is thin, forming Qinghai's unique plateau climate characteristics, namely: low temperature, dry, windy, and oxygen-deficient. The annual average temperature in Qinghai is minus 5.8°C to 8.6°C, and the temperature varies vertically with altitude. Due to the influence of climate, environment, humanities and other factors. [0003] Chinese Patent Application No. 201410687098.2 discloses a frost-resistant habitat substrate for alpine regions and its preparation method, which is applied to slope ecological protection engineering, g...
