油茶早期密植栽培,能充分利用光能和地力,单位面积产量高。如武义百花山林场1958年发展的650亩油茶,每亩120株,1966年平均亩产油7斤多,其中2亩高产试验林亩产茶油61斤。但是,随着树龄的增长,树冠扩大和枝叶交错封行,由于阳光不足,树冠内部枝条干枯,结果位置上移,树势急剧下降,形成了这样一种现象:从树龄看是刚进入结实盛期,却又大幅度减产。为了解决这一问题,从1972年起,在林场党支部的领导下,我们成立了场站三结合科技小组,开始了间伐试验。现在,场
Camellia early close planting cultivation, can make full use of light and ground force, high yield per unit area. Such as Wuyi Baihua Mountain Forest Farm in 1958 the development of 650 acres of tea, 120 acres per mu, 1966 an average of more than 7 pounds per mu of oil production, of which 2 acres of high yield test yield of 61 acres of tea oil tea. However, with the increase of the tree age, the crown of the tree is enlarged and the branches and leaves are interlaced with each other. Due to insufficient sunlight, the branches inside the crown are withered off, the position of the tree is moved upward and the tree vigor drastically declines, forming a phenomenon that, Period, but a substantial cut. In order to solve this problem, from 1972 onwards, under the leadership of the Forest Farm Party Branch, we set up a three-team team to start the thinning test. Now, the field
