油茶是我国特有的木本食用油料树种,遍及秦岭淮河以南15个省(区),面积约6000万亩,是目前栽植面积最大的经济树种。但单位面积产量低,平均亩产茶油一般只有2. 5-3公斤。为改变油茶经济效益低的状况,林业部于1983年,1984年分两次下达湖北省林科所、麻城市林业局在麻城市开展5000亩(其中:1983年3000亩,1984年2000亩)低产油茶林的改造及丰产技术推广任务。
Camellia oleifera is a woody edible oil tree species endemic to China. It covers 15 million provinces (districts) south of the Huaihe River in Qinling and covers an area of about 60 million mu. It is currently the largest economic tree species planted. But the yield per unit area is low, the average yield of tea oil generally only 2. 5-3 kg. In order to change the low economic benefits of Camellia oleifera, the Ministry of Forestry issued the Forestry Branch of Hubei Province in 1983 and 1984 in two places, and the Forestry Bureau of Macheng City carried out 5000 acres in Ma City (of which: 3000 mu in 1983 and 2000 mu in 1984) Transformation of low-yield Camellia forest and the task of promoting high yield techniques.
