前言我国为山茶属植物主要分布国家,种质资源丰富,目前已掌握的有200多种。在利用上有的以食用油料为主,有的以花卉观赏为主,也有的两者兼备。这是我国重要的资源财富,加以发掘收集和和利用,对科研、生产都有重要意义。山茶属物种,品种繁多,水平分布南至热带,北至温带,垂直分布从海拔几十米到2千5百多米。不同的种,其生态学和生物学习性明显不同,有的3—5年便可开花结实,有的需要8—15年才能开花结实。将分布在各地的物种和品种发掘收集起来,加以利用,这是科研中首先要
Preface Our country is mainly distributed in the country Camellia, germplasm resources are rich, there are now more than 200 species. In the use of some edible oil-based, and some ornamental flowers, and some of both. This is an important resource and wealth of our country, which is to be explored for collection and utilization. It is of great significance to scientific research and production. Camellia species, variety, horizontal distribution of the south to the tropics, north temperate, vertical distribution from tens of meters to more than 2500 meters. Different species, their ecological and biological habits were significantly different, some 3 to 5 years can flowering, and some need 8-15 years to flowering and fruiting. The distribution of species and breeds scattered around the collection to be used to make use of, this is the first scientific research
