摘要
本文通过17年固定标准地观测,证明组成油茶产油量的主要因子是单株产果量和鲜果含油率.影响单株产果量,大果优于中、小果;早花优于中、晚、特早花;紫红、红果优于青皮果.在偏北地区.花期气候是影响油茶产量的最重要外界因素.油茶选种应以单株为主,着重早花、大果、高鲜果含油量等性状选择,果实成熟度要一致.
Based on a 17-year study with fixed plots, the article argues that the fruit yield of each individual plant and the oil content of the fresh fruits are the two major factors which affect the oil quantity of oiltea camellia ( Camellia oleifera). The fruit yield of each individual tree varied with the fruit type, the time of flowering as well as the fruit color. While the big-fruit, reddish-purple and red-fruit types bore more fruits than the small-fruit, green-fruit types, early flowering was better for fruit bearing than late flowering and over-early flowering. In the far North, the climate during the flowering phase was the most important factor that influenced the fruit yield. Therefore, it is suggested that greater attention be paid to the individual plant when selecting variety, and priority should be given to those trees which possess the characters of early flowering, big fruit, and high oil content in fresh fruits.
