乌桕(Sapium Sebiferum I.Roxb)是大戟科(Euphorbiaceac)乌桕属(Sapium)的落叶乔木,别名桕子、木子、枧子等。是含油率很高的木本油料树之一。乌桕油脂是手工和轻工的重要原料。随着科学技术的发展,乌桕油脂又广泛应用于军事工业和化学工业。我省是乌桕产区之一,栽培遍及全省各地,目前有实生和嫁接的乌桕树约2190万株。在广大分布区内,乌桕林生长的好坏和产量的高低,相差十分悬殊。这种差异的原因,除了乌桕品种本身的遗传因素之外,与栽培地段内的生态关系非常密切。为此,根据我省现有乌桕的分布情况,进行调查分析,探讨乌桕的群落生态关系,对今后因地制宜发展乌桕生产,具
Sapium Sebiferum I.Roxb is a deciduous tree belonging to Sapium of Euphorbiaceae, alias Prunus mongolica, Muzi, prickly heat and so on. It is one of the woody oil trees with high oil content. Wuhu grease is an important raw material for handwork and light industry. With the development of science and technology, Wuhu grease is widely used in military industry and chemical industry. The province is one of the Wuzuo producing areas, cultivation throughout the province, there are currently about 21.9 million Umbelliferae trees of real life and grafting. In the vast distribution area, the growth of Wuzhailin good and bad and the level of output, the difference is very poor. The reason for this difference, in addition to the genetic factors of the species, is closely related to the ecology in the cultivated area. To this end, according to the distribution of the existing clam in our province, carry out investigation and analysis to explore the ecological relationship of clam clam community, the future development of black clam production in line with the local conditions, with
