Study On Primula Genera Plants And Its Rhizosphere Soil Nutritive Elements Accumulation Of Shergyla Mountain In Tibet

Tibet wild Primula genera plants rich in resources and has enormous potential for development and utilization. Primula genera plants are an important part of the wild flowers and vegetation of the Tibetan region, but also research and breeding of new varieties of flowers is extremely important herb resources and high-quality materials for landscaping. Plant germplasm resources of Shergyla Mountain wild Primula survey laid the foundation for improved varieties and breeding new varieties of Primula plants.The wild Primula plant research project, different types of Shergyla Mountain, elevation, aspect and vegetation cover.11different samples, using GPS positioning system set up in the mountains and then the same set two quadrats Primula plants and their habitats, soil nutrient element accumulation and distribution of measurement and experimental analysis, introduction and domestication of plants and the development and utilization to provide a theoretical basis and technical support to the case of China as a wild primrose. The survey research has an extremely important scientific value and social significance.The research Primula Determination of plant nutrients:total nitrogen, total phosphorus, total potassium, calcium, magnesium, iron, zinc, manganese, copper, sodium and chromium11kinds of elements; Primula plant rhizosphere determination of soil content include:pH, organic matter, total nitrogen, hydrolysable nitrogen, total phosphorus, available phosphorus, potassium, potassium and slow potassium; Primula plant rhizosphere soil were measured t(?)ace elements:iron, zinc, manganese, copper and effective boron. Not the same Primula plants nutrient element contents and their habitat soil element content determination and test analysis, found that a certain degree of correlation exists between the soil elements of the Primula plants element and its habitat.Through research, found the species of wild Primula genera plants growing in the mountains Shergyla rhizosphere soil element content and the Primula genera genus there is a certain correlation among the nutrient element c(?)tents between plants and understanding of the regional wild primrosesoil nutrient element contents of the demand index, and for the Tibet wild primrose is a plant protection, development and introduction and domestication provides a theoretical basis, but also provides professional technical support for the various sectors of the plant kingdom.
