油茶是我国南方主要木本油料树种,具有悠久的栽培历史,当前油茶单位面积的产量普遍偏低。据统计,油茶常年亩产油3—6市斤,如以每百斤果榨油6市斤计算,则每亩只结果50—100市斤。据在湖南道县、宁远等9个县、81个油茶林标准地调查,不结实株或单株结果量在1市斤以下的株数频率为70%左右,单株结果量1市斤以上的株数频率只30%左右,可见油茶结果量集中在约1/3的植株上。现将广东韶关地区林科所,连续3年调查5亩油茶林的结果情况列入表1。
Camellia oleifera is the main woody fuel tree species in southern China, has a long history of cultivation, the current yield per unit area of Camellia generally low. According to statistics, annual output of tea oil 3-6 kg per mu, such as per kilogram of fruit oil press 6 kg calculation, only 50-100 pounds per mu per acre. According to the standard survey in 81 counties of Camellia oleifera in 9 counties such as Daoxian and Ningyuan in Hunan province, the frequency of unframed or single plantlets below 1 kg was about 70%, and that of more than 1 kg per plant Frequency of only about 30% of the number of trees, the results can be seen concentrated Camellia in about 1/3 of the plants. Shaoguan now in Guangdong Lin Branch, 3 consecutive years of investigation 5 acres of Camellia oleifera results are listed in Table 1.
