Perennial Root Flower Species Selection And Configuration Reserch Of ZhuZhou

With the development of urban construction, perennial flowers in the city in which the use of more and more attention. A wide variety of perennial flowers, ornamental effect is good, strong resistance, if appropriate combination of not only color, flower-shaped variety, each season can last spring and autumn flowering, easy to manage and easy to create a good landscape plant landscape. However, the current Zhuzhou how to choose a suitable perennial flowers no corresponding studies, the lack of systematic theoretical support. So, how to be screened and the introduction of perennial flowers used in Zhuzhou city green space, the region is very urban greening quality reconstruction concern.Through literature review, field surveys, select the filter indicator to establish the Analytic Hierarchy Process (AHP) model, gray correlation analysis model and floral combinations cultivation experiments and other methods, research Zhuzhou City from flower applications open field, formulation may be suitable Zhuzhou perennial flowers planted55kinds,55kinds of the proposed introduction of a comprehensive value assessment perennial flowers and perennial flowers combined portfolio allocation experiments conducted ecological research in this adaptation, ornamental and garden applications, take the following research results:(1) By the results of Zhuzhou city parks and more than three green investigation showed that26kinds of commonly used open field of flowers, use a low frequency of perennial flowers. In the garden using a higher frequency of nine kinds of flowers, then the main use of annual and biennial flowers, accounting for six kinds, the proportion reached70%; the remaining three kinds of perennial flowers there are two kinds to make a biennial cultivation; common varieties of perennial flowers only common species of flower chrysanthemum, lily, orchids, green onions, the proportion is only30%; application form various types of flowers and more single combination of the clutter.(2) Using the analytic hierarchy process and correlation analysis model for the introduction of the55kinds of desire perennial flowers comprehensive value judgment. And to strengthen the correlation based on the final results of sort, the55 kinds of perennial flowers are divided into three levels. The first stage:weighted correlation>0.7513kinds of perennial flowers, high-value, can be widely used; The second stage:0.75> weighted correlation>33kinds of varieties of perennial flowers0.65, the value generally promote the use, The third stage:weighted correlation<0.659varieties of perennial flowers species, application of low value and should be used with caution in Zhuzhou.(3) Two dwarf perennial cultivation floriculture combined mode used in the experiment can grow well in Zhuzhou, budding short time, budding rate, and quickly covered the ground, in40days you can see the flower planting. Heaven dwarf perennial chrysanthemum, carnation, chrysanthemum growth performance of sulfur good. Caryophyllaceae and Asteraceae plants dominant position. Adaptability, compete moisture, nutrients, spatial ability dominant. Flower onion, poppy and other growth margins being squeezed, the performance slightly worse.Autumn perennial flowers combination experiments excluded lupine, columbine dishes Zhuzhou poor adaptability of plant species, based on the growth of plants and ecological performance of plants used to adjust the appropriate mix of several groups to establish a more stable plant configuration combinations. As perennial flax/Penstemon/flower onions, dwarf perennial Gaillardia/Echinacea purpurea, sulfur Chinese chrysanthemum/Janome daisy/carnation, perennial Gaillardia/low snow wheel. These can be adapted to local conditions with the use of a variety of landscapes in Zhuzhou flower beds, flower border, water, special garden, gardens, etc. into being.(4) Greenfield Allocation of Zhuzhou City, according to the parks and residential areas, waterfront, roads and other categories of perennial flowers green application form and principles. Investigate specific for Zhuzhou City Urban Plant perennial flowers landscape dominated configuration.Taking these results of the mathematical model and experimental studies, and ultimately determine the appropriate Zhuzhou City planted25kinds of varieties of perennial flowers, perennial flowers and explore a combination in the park and residential area, waterfront green space and depending on the type of road green three main Zhuzhou Flowers and Plants green type of application, and were recommended: parks and residential green space:six kinds;waterfront green space:five kinds; road green:3kinds.Total14kinds of perennial flowers configuration mode.
