为了探索提高低产茶园改造效果,加快低产茶园改造步伐,提高茶叶生产经济效益,我们采用两种重修剪方法改造低产茶园。 试验地选在玉环县古城乡曾家茶场15年生的常规茶园内,茶树品种为本地群体种,未老先衰,1989年亩产干茶25公斤。 今年5月7日提前结束春茶生产后,在树势基本一致处设两个小区试验处理:(1)茶树重修剪常规法(对照区),用篱剪剪去离地面30厘米以上的全部茶树枝叶,(2)中国茶科所薛云岚研究员介绍的斯兰里卡茶树重修剪法(以下简称斯里兰卡法),即每茶丛暂留一根长势较强枝条,用篱剪剪去离地面30厘米以上的其余枝条,经过30天到35天,在每丛骨干枝上长出带有一片真叶,约5厘米
In order to explore and improve the low-yielding tea transformation effect, accelerate the pace of low-yield transformation of tea, tea production to improve economic efficiency, we use two kinds of heavy pruning methods to transform low-yield tea plantation. Experimental selection in the ancient city of Yuhuan County Zengjia Chachang 15-year-old conventional tea plantations, tea varieties for the local species, not old before the first decline in 1989 mu 25 kg of dry tea. May 7 this year, ahead of the end of spring production of tea, the tree is basically the same at the same set of two plot trial treatment: (1) tea trimming routine (control area), hedge trimmer to remove all 30 cm above the ground Tea tree branches and leaves, (2) Silarika tea pruning method (hereinafter referred to as Sri Lankan law) introduced by researcher Xue Yunlan of the Chinese Tea Institute, that is, leaves a strong growing branch for every tea bushes, cut off the ground with hedge trimmer 30 The remaining branches above centimeter, after 30 days to 35 days, grow on each bony branch with a true leaf, about 5 cm
