Investigation In Solanaceae Plant Resources And Evaluation Of Landscape Application

The development and utilization of some new plant resources of landscape has become the urgent requirement of the present development of diversity of plant landscape.In order to meet the development needs of the plant landscape diversity, should exploit more ornamental plant resources for plant landscape design.Based on the research of Solanaceous plants as the main line, access to all kinds of information to understand the basic information of the Solanaceae such as historical research, ornamental plant species,morphology, distribution of resources. Solanaceae species known in the world there are 30 genera 3000 species, mainly distributed the temperate and tropical regions in the world, especially in the tropical American species is the most abundant. The field survey in Fuzhou City,41 urbans and 2 flower markets, using the analytic hierarchy process to applicate and evaluate in landscape, were evaluated from three aspects: aesthetic, ecological adaptability, resource value, and discuss the evaluation results.The main research results:(1) By the literature analysis, the scope of application of the Solanaceae is wide, can be used as greening material for the beautification of the city; ornamental vegetables can be eaten and beautify the living room; to protect the ecological environment. It has a long history of medicinal value.(2) Through the consult books and literature, summarized the Solanaceae 18 genera of ornamental plant resources, and to plant flowers, color, shape, fruit and ornamental value, economic value, medicinal value and so on.(3) Survey43 samples in the green plants of Solanaceae in Fuzhou. The Solanaceae mainly in the flower market. Planting form of Solanaceae plants is single in the city green space, application of plant species is less, low frequency, landscape configuration mode is simple without beauty.(4) By using the analytic hierarchy process, to establish a comprehensive evaluation system of Solanaceous plants, landscape application of 18 solanaceous plants of the investigation, and according to the evaluation value of the size of the rank ordering of it. The weight of aesthetic factor was the highest, it is 0.6370. The total order weight value weights in plant type, aromatic, flowering, fruit shape, color,distribution, ecological habits of the value is in the top seven.(5) The comprehensive index of 18 solanaceous plants of each evaluation index is sorting andgrading in Fuzhou, that draws:Brunsfelsia acuminate is the first level, has a high value of development, suitable for large-scaledevelopment and utilization; Solanum wrightii、Cestrum aurantiacum、Lycium chinense、Capsicum annuum var.onoides、Solanum pseudo-capsicum var.diflorum、Cestrum nocturnum、 Calibrachoa hybrids、Petunia hybrida is the second level,has a higher value of development, can moderate development; Nicotiana alata、Datura stramonium、 Datura aruea、 Lycopersicon esculentum、Capsicum annuum、Solanum mammosum、 Solanum torvum is the third level, hassmall scale of development and utilization, dotted the city landscape.(6) According to the comprehensive evaluation results, Combined with the factors of numbers of plant resources, ecological value, medicinal value, mainly the application form in the landscape of Solanaceous plants, such as potted plants, flower terrace, vertical greening, special categorized plants garden, and detailed introduction of landscape plant species can be used, as well as specific applicationsand location.
