Abstract

- This study was carried out to offer the raw data on the method of cultivation and ecological characteristic bysystematical analysing habitat environment of Tulipa edulisthat was expected as medicinal and ornamental resource.The habitat environment was that the altitude was 245 m, the aspect of south, the size of approximately 49 , and therewas analyzed that Tulipa edulis grew wild in the dryly sunny spot. The vascular plants were summarized as 62 taxa; 28families, 59 genera, 50 species, 11 varieties and 1 forms, and the resource plants were classified that there were 23 taxaof ornamental plants(37.1%), 43 taxa of edible plants(69.4%), 34 taxa of medicinal plants(54.8%) and 29 taxa ofothers(46.8%). In the results of soil factors analysis, there showed that acidity was pH 4.9, organic matter content of4.9%, available P2O5 of 3.6 / , exchangeable K+ of 0.5 cmol+/ , exchangeable Ca2+ of 3.0 cmol+/ , exchangeableMg2+ of 0.8 cmol+/ , cation exchange capacity(C.E.C) of 12.3 cmol+/ and electrical conductivity(EC) of 0.3 dS/m. Inthe results of correlation analysis between soil factors, exchangeable Ca2+ and C.E.C were highly correlative. The growthcharacteristics of Tulipa eduliswere surveyed that height was 7.6 , leaf width of 0.6 , leaf length of 12.7 , flowerwidth of 2.8 , peduncle of 5.4 and chlorophyll of 34.7 -1. In the results of correlation analysis betweengrowth characteristics, height and peduncle were highly correlative. In the results of correlation analysis between soilfactors and growth characteristics, exchangeable K+ and leaf length were high relativity but they were confirmednegative relation. In the results of growth model analysis, R-square of leaf width and exchangeable K+ was some 86.4%and that of chlorophyll and exchangeable K+ was some 83.7%Key words -Model, Habitat, Soil, Growth- 181 -- 182 -
