Soil Texture Analysis And The Choice Of Plants

With the accelerating urbanization process, urban greening plants for the survival of the soil is undergoing tremendous changes and original soil into the special urban soil, pollution is aggravating gradually, serious lack of nutrients, performance continued to decline, leading to green plants cannot normal growth, directly affect the urban greening on ecology and landscape effectiveness of play. Therefore, according to the characteristics of urban soil, study and explore the urban soil and plant growth, and combined with the actual to pick a suitable growth of garden plants, do scientific selection, scientific cultivation, conservation science, to meet the urban construction, people "s life, the landscaping demand and urban landscape greening construction is crucial.Taking Xi’an city road greening soil texture of plants influence as the main content, the soil texture in the Third Ring Road and its relationship with plant of relevant physicochemical analysis, in-depth research, according to the test results show that collected samples with pH value of alkaline and high soil organic matter content, soil available nitrogen, phosphorus and potassium content is below the average, resulting in Third ring road sections of seedlings to soil, showed poor growth, and even death.Through analysis and research, hereby from the soil, planting points and different soil texture choice different plants of and suggestions are put forward on the Third Ring Road in Xi’an soil texture and plant selection and configuration, to improve the third ring road greening effect play an important role for future urban greening construction to provide a scientific basis.
