Problems solved by technology

Because the growth and reproduction cycle of plateau meadow herbs is too short, this type of herb plants are planted in ecologically degraded alpine habitats. Since the root system of the growing plants has not yet fully developed, the plateau meadow has entered the permafrost season. It is difficult to withstand the test of severe cold, and the survival rate is low

Abstract

The invention relates to a method of cultivating herb plants which grows in cold belt environment, comprising cultivating the mesophyte perennial herb small plants with strong underground root with nutrition maintaining bags, cultivating with different temperature of day and night in the cultivating house, spraying the foliage with auximone, replanting the qualitative plant during the first days in May of each year and intensive planting. The method is suitable for cultivation and repair planting of mesophyte perennial herb plant in meadow steppe of ecological degeneration and desert or bare earth and cave, and the survival rate is higher than 85%.

Description

technical field [0001] The invention relates to a method for cultivating herbaceous plant seedlings adapted to alpine habitats. Background technique [0002] The Qinghai-Tibet Plateau spans the subtropical, warm-temperate, temperate and cold-temperate zones. With its unique geographical environment and special climatic conditions, it has developed a unique large-scale alpine wetland, alpine meadow, alpine grassland and alpine desert ecosystem in the world, giving birth to the Qinghai-Tibet Plateau. The unique biota, known as the natural germplasm resource bank of alpine organisms, is the area with the highest concentration of biodiversity in high-altitude areas in the world. The alpine meadow grassland is formed by cold-resistant mesophyte perennial herbs and shrubs such as alpine steppe wormwood meadow, alpine wormwood meadow, alpine shrub meadow, alpine steppe grassland and swamp wormwood meadow subclass. The special geographical location of the Qinghai-Tibet Plateau, the...
