| Qin-ba mountain area and its surroundings is one of most abundant distributions of wild lilies in China. In recent years, with the increasingly serious ecological environment deterioration in the region, wild lilies are facing severe survival and reproduction crisis. The commercialization of ornamental lily in China is still in its initial stage while its breeding and reproduction work is lagged far behind. Although in recent years we have made some breakthrough, some technical problems still exists in the seed production process. This experiment studies five wild lilies growning in Qin-ba mountain area, from the soil characteristics of its native locations to reproduction characteristics of its scale, providing a scientific reference to the introduction and domestication, cultivation management and rapid micro-propagation and utilization of wild lilies. Meanwhile, this experiment also studies the growth of three of the most popular commodity lilies from the respect of its growing media and fertilizing proportion in order to find a rapid, effective growth matrix and fertilization ratio, solving problems occurs in the localizational process of the production of commercial seed bulbs. Research findings are as follows.1. Different kinds of wild lilies vary distinctly from each other in organic matter, total nitrogen, total phosphorus, total potassium and soluble calcium in their proterozoic habitat soil, and so does the same kind in different ecotype. For example, the average content of organic matter of Lilium leucanthum’s proterozoic is43.70g/kg, with different ecotypes vary from14.78g/kg to90.0g/kg. And that of Lilium brownie is22.02g/kg, different ecotypes ranging from10.56g/kg to44.82g/kg.2. The ranking of these five wild lilies’soil nutrient condition from higher to lower are as follows:Lilium leucanthum:89.57, second degree; Lilium pumilum:84.37, second degree; Lilium duchartrei:82.05, second degree; Lilium lancifolium:65.23, third degree; Lilium brownie:63.84, third degree. The soil nutrient condition of different ecotypes of the same kind of wild lilies’proterozoic differ obviously from each other. The rating range of all ecotypes of Lilium leucanthum are95.38, first degree to53.03, fourth degree. And that of Lilium pumilum95.38, first degree to43.77, fourth degree; of Lilium duchartrei95.38, first degree to71.04, third degree; of Lilium lancifolium71.04, third degree to30.44,fifth degree; of Lilium brownie 93.07, first degree to28.40, fifth degree.3. The cutting propagation of the scales from different species of wide lillies produce different size of bulb-lets as well as propagation coefficient. The bulb-lets of lilium leucanthum are the biggest, with the circumference of2.91cm and weight of0.53g, while that of lilium duchartrei are2.05cm and0.14g respectively. As for the coefficient of cutting propagation, the figure of lilium lancifolium thunb is2.10, ranking the highest, while that of lilium duchartrei is0.75.4. The reproductive characteristics of different ecotypes of the same species varies from one another. For example, the circumference, weight and propagation coefficient of lilium leucanthum’s bulb-lets from Xinlin Village Pingliang Town Hanyin county Shanxi province are3.45cm,0.71g and1.67respectively. However, the figures of lilium leucanthum’s bulb-lets from Shagou village Fengdie town Zhouqu county Gansu province are2.57cm,0.33g and0.99respectively.5. There are obvious positive corelation between the weight of the scales and its bulb-lets with the corelation coefficient of the weight of scales and the circumference of bulb-lets being0.716and that of the weight of scales and the weight of bulb-lets being being0.714.6. Among the five kinds of wild lilies, the growth of Lilium lancifolium bulbs is the best. In the media of corn stalk:sand=4:1, its seedling emergence rate, the rate of bulbs acquired, the weight and circumference of the bulbs are87.19%,84.69%,0.28g and3.23cm respectively. Followed by Lilium leucanthum in the media of peat:perlite=2:1, of51.75%,51.75%,1.2g,3.52cm respectively.7. Different Medium and Fertilizing Proportion have significant influence upon the Growth of Lily Bulb-lets. Taking their plant morphologies, the size of bulb-lets underground, the physiological and biochemical index and other relative factors into consideration, both Lily Sorbonne and Lily Marlon grow best under the condition of (corn stalk:Vermiculite=1:1)*(N:P:K=10:5:15). Lily Siberia displays best growth status under the same media (corn stalk:Vermiculite=1:1) plus Fertilizing Proportion of N:P:K=15:5:10. |
