国外,斯里兰卡、印度,东非等产茶国于七十年代,广泛采用“弯枝法”,代替了传统的定型修剪。近年来,我国的广大茶区也引进使用“弯枝法”培养幼龄茶树的树冠,效果良好,现将我场热作实验站开展的试验结果初报如下: Foreign countries, Sri Lanka, India, East Africa and other tea-producing countries in the seventies, widely used “bend twig method”, instead of the traditional stereotypes pruning. In recent years, the majority of tea areas in China have also introduced the use of “bend sticks” to cultivate the canopy of young tea trees, with good results, the results of the experiment conducted by our field hot work station are as follows:
