Study On Resource, Introduction And Cultivation Of Wild Lily

Lily is perennial bulbous flower and also famous ornamental flower in the world. China is rich in the wild lily resources,and has a lot of endemic species which are widespread, which are precious original material and play a very important role in the Word Cultivation. However, the seed bulb of Chinese have not get appropriate application. In view of this question,the auther studied on resource, introduction and cultivation, reproduction of wild lilies in northwest of Yunnan and Erdaobai River of Changbai Mountain.The auther collected 7 spescies of wild lily in Yunnan, which are Lilium bakerianum, L.bakerianum var.delavayi, L.amoenum, L.sulphureum, L.nanum, L.souliei and L.duchartrei. L.bakerianum distributes at 2700-2900m altitudes in Haba Snow Mountain,where is brown forest soil. L.bakerianum var.delavayi distributes at 3000-3100m altitudes in Baimang Snow Mountain,where is dark brown forest soil. L.amoenum distributes at 3010m altitudes in Yulong Snow Mountain,where is meadow soil. L.sulphureum distributes at 1900-2100m altitudes in Yulong Snow Mountain, where is brown forest soil. L.nanum distributes at 2700-3500m altitudes in Baimang Snow Mountain,where is forest soil. L.souliei distributes at 3500-4200m altitudes in Yulong Snow Mountain and at 3000m altitudes in Baimang Snow Mountain, where respectively is meadow soil and forest soil, and some mixes live with L.bakerianum var.delavayi. L.duchartrei distributes at 2700-3100m altitudes in Baimang Snow Mountain,where is dark brown forest soil. Baimang Snow Mountain at 2700-3100m altitudes is the most rich in lilies,including L.nanum,L.souliei, L.bakerianum var.delavayi and L.duchartrei,where plant community is Abies fabric—Fargesia sp.—Rhododevdron simsii—Meconopsis integrifolia, Athyrium sp, Viola adenothrix and Poa annua. Most of them distribute scattered in the forest edge, grassy slope, hillside and nearby brook. There are 3 spescies of wild lily collected from Changbai Mountain, which are L.distichum, L.dauricum and L.lancifolium, their altitudes is about 800m. L.distichum distributes in the forest edge, L.dauricum and L.lancifolium distribute in roadside and forest edge,whose habitats are bad, and they have strong compatibility. In 50% —100% light conditions, L.dauricum grows strongly,in 30%,which grows fragile, and in 15%, which grows diminutive and whose flower is small.In the introduction and cultivation experiment, seed phase of 7 wild lilies is concentrated at the beginning of March,then growed quickly until May, and the height did not change from the end of May to the beginning of June, being suitable for climate condition of Beijing. Only Lilium bakerianum and Lilium duchartrei blossomed and bore fruit,and other lily did't blossom and had lodging in growth. The cuttage propagation experiment of L.dauricum demonstrated that only bulb scale with base can inducts bulblets and it is suitable to cottage in high humidity, which inductivity is 93.4%. After having inducted bulblets, transplanting to soil can promot roots to grow. In germination of seeds experiment, variance analysis indicates that the effect of temperature is remarkable and seed rate is highest in 20°C ,82%. The effect of light intensity to seed germination is not remarkable,but according to germination tendency it is best to choice 20°C and dark condition. Through researching on climatic conditions and wild lilies distribution and comparing with climatic and soil conditions of lily bulbs production area of Holland and Kunming,Beijing has condition to establish germplasm resources garden and bulbs production base, at the same time, the auther selected 12 suitable areas.
