油茶是异花授粉、自花不孕的树种,由于栽培历史悠久,分布区域广,这就使其在生育特性、抗性、丰产性、成熟期和品质等方面出现许多变异性.目前油茶生产品种类型混杂(据本场调查就有7个品种类型),良莠不齐,单位产量低.但据中国林科院亚林所报道,在现在栽培的油茶群体中,散生着约25—30%的高产稳产的单株,它们的产量约占总产的70—
Camellia is cross-pollination, self-infertility tree species, due to a long history of cultivation, the distribution of a wide area, which makes it in fertility characteristics, resistance, high yield, maturity and quality, etc. There are many variability now Camellia production Mixed varieties (according to the field survey there are 7 varieties), good and bad, the unit yield is low, but according to Chinese Academy of Forestry Yalin reported that in the current cultivation of Camellia oleifera, scattered about 25-30% High yield and stability of the individual plants, their production accounts for about 70-
