油茶是我省主要木本食用油料树种,长期以来,油茶产量很低,平均每亩产油不到4公斤。据中南林学院李克瑞等同志对本县油茶林的调查分析表明,油茶低产的主要原因是林分中存在着高频率低产株和不结果株。为提高油茶产量,长期以来,人们一方面对油茶实生林进行垦复、施肥、修剪等营林技术措施,但产量不稳定;另一方面利用油茶优树种子进行实生苗造林,期望通过有性手段来改良油茶种
Camellia is the main woody edible oil tree species in our province. For a long time, the yield of camellia oil is very low, with an average oil yield of less than 4 kg per mu. According to Zhongli Forestry College Li Kerui and other comrades on this county Camellia forest survey showed that the main reason for the low yield of Camellia oleifera is the existence of high-frequency low-yielding and non-yielding strains. In order to improve the yield of Camellia oleifera, people have for a long time carried out technical measures of reclamation, fertilization, pruning and other silviculture, but the yield was not stable. On the other hand, seedlings of Camellia oleifera seedlings were used for seedling afforestation, Means to improve Camellia species
