我场现有茶园230亩,采摘面积170亩,其中有150亩从1956年投产至今已有19年。历年来对老茶园虽然进行轮回台刈更新,但由于采养失调,这些老茶树冠面均形成多层鸡爪枝,萌发的芽叶小,叶片薄,产量低,采摘工效低。为了探求恢复树势促进增产的可靠途径,我场于1973年春季在青年湾对1953年直播的一亩双行条列茶园进行轻修剪和深修剪对比试验,到年终比较产量,轻修剪的0.52亩,亩产鲜叶1,575斤;深修剪的0.48亩,
My field has 230 acres of tea plantation, picking area of 170 acres, of which 150 acres from 1956 put into operation for 19 years. Although the old tea plantations have been reincarnated for many years, the old tea plantations have many layers of chicken-claw branches because of maladjustments. The sprouted buds are small and the leaves are thin with low yield and low picking efficiency. In order to find out a reliable way to restore the vigor of the tree and to increase yield, I conducted a light-weight and deep-manicure comparison trial on the acreage of double lines in 1953 in Qingnian Bay in the spring of 1973 to compare with the year-end yield of 0.52 Mu, 1,575 kg of fresh leaves per mu; deep pruned 0.48 acres,
