Study On Selection Of Euscaphis Japonica Superior Individual And Landscape Plants Implementation Design

Euscaphis japonica belongs to the Staphyleaceae, Euscaphis genus, is a one of a kind of previous medicinal ornamental tree plants, has outstanding ornamental value, economic value and the scientific value. It is a small tree species endemic to China, with strong development and application prospects. Current research on plant Euscaphis japonica mainly focused on the morphological classification, ecological biology, breeding and cultivation, pharmacology and physiology and biochemistry, etc., while facing the comprehensive evaluation research of horticultural traits that Euscaphis japonica superior individual were poorly understood, and its garden landscaping applications have not been systematically studied. Euscaphis japonica garden application is also a lack of complete rationality theoretical guidance and methods, and the level of application of greening is behind.The ornamental value of the morphological parameters of 17 Euscaphis japonica superior individual were studied in the autumn of 2013,2014, in Shaowu Jiangshi Nature Reserve Euscaphis japonica Superior individual trial bass, and then use the Analytic Hierarchy Process to evaluate ornamental characteristics based on the research. From the study results of the ornamental characteristics mentioned above, combined with the guidelines and principles of landscaping plant configuration, proposed the configuration mode of Euscaphis japonica and landscape elements. The conclusions of each research were listed as follows:1. By using Analytic Hierarchy Process (AHP) to establish the integrated evaluation system for Euscaphis japonica superior individual on ornamental characteristics criterion level and index level. Its structure is:target level (A):refers to the comprehensive evaluation of ornamental characteristics for Euscaphis japonica superior individual; the criterion level (C):plant type C1, fruit C2; index level P, reflecting constrained level and Euscaphis japonica superior individual ornamental character evaluation of a representative 10 specific indicators. Weight of each factor criterion level and index level are C2> C, and P7>P,>P9>P,o>P6>P2>P3>P4>P8>P5. Constraining level fruit more important than the plant type, is the basic position Euscaphis japonica ornamental value traits, plant type, but also showed its indispensable position, both with, constitute Euscaphis japonica superior individual ornamental value absolute influence. In the index level, per plant panicle distribution (P7) maximum weight value 0.2195, indicating a greater contribution rate which Euscaphis japonica superior individual largest ornamental traits, per plant panicle distributed at the macro landscape ornamental value. The loose plant type (P1) of the weighted value of the second, as 0.1667, indicating that it Euscaphis japonica superior individual ornamental value position to occupy an important position, about the overall level of ornamental value. Panicle’s color (P9) and per plant panicle’s number per plant (P10) two weights are 0.1199 and 0.1115, its importance Euscaphis japonica superior individual in ornamental value in the third and fourth place, explained in ornamental fruit plants, people on the ’color’,’number’in the visual requirements are very obvious. The impact on the ornamental characteristics Euscaphis japonica index evaluation system:panicle’s weight is the least, indicating that fruit plants in Euscaphis japonica panicle’s weight view is not determined its ornamental value tendency.2. The comprehensive evaluation of ornamental characteristics for Euscaphis japonica superior individual. Sort results of Euscaphis japonica superior individual’s test for ornamental traits:17 Euscaphis japonica superior individual ornamental value for five grades, respectively arranged as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, Ⅴ grade, ornamental value decreased gradually. They sort of ornamental value:S16> S11> N1> S17> N7> N2> S12> N5> N6> N4> S8> S13> S10> N3> S9> S15> S14. The S16, S11, N1, S17, N7, five superior individuals which could be selected as the superior cultivars for the popularization and application of garden greening, the remaining superior individual were cultured as germplasm collected.3. Studies on the garden landscaping mode of Euscaphis japonica. According to the characteristics of regional climate, with reference on the other ornamental fruit plants model case, as well as the performance of integrated Euscaphis japonica ornamental traits, put forward Euscaphis japonica create landscape constructions under the guidance of plant landscape planning and design theory, including the landscape creation of courtyard, the forest edge meadow, garden road and waterscape space.
