随着茶树年令的增加以及长期采摘刺激,使树冠生长势衰退,鸡爪枝增多,茶芽短而轻,对夹叶多,造成品质下降,产量不稳定,必须深修剪改造树冠,复壮茶树生长势。通过1972—1977年茶树深修剪研究表明:1.衰退茶树深修剪效果和作用是提高茶树生长势,增强育芽能力,增加茶芽长度和重量,提高正常芽叶百分率。所以茶树深修剪有复壮树冠,稳定 With the increase of tea time and the long-term picking stimulus, the growth of the canopy declines, the number of chicken legs increases, the tea buds are short and light, the number of the leaves is more than that of the tea leaves, resulting in declining quality and unstable yield. Potential. Through 1972-1977 tea tree pruning studies have shown that: 1.Decay tea tree deep pruning effect and role is to improve tea plant growth potential, enhance the ability of sprouting, increase tea bud length and weight, increase the percentage of normal shoots. Therefore, deep pruning tea tree canopy, stable
