该文通过试验示范和调查后，提出贵州地处亚热带，自然条件适于茶树的生长，是茶叶原产地和我国主要茶叶产区之一，但目前单产水平低于全国平均数四分之一以上。调查与试验结果表明，低产茶园面积大、投入不足、管理粗放、经营不善是影响茶叶增产的主要原因；今后茶叶生产的重点应放在提高现有茶园单产和茶叶品质上。深耕改土、培肥茶园是提高茶园单产的基础；在此同时采用更新树冠、复壮树势、增施肥料、合理定型修剪、适时采摘、防治病虫害、加强管理等综合技术措施，将使低产茶园迅速恢复生机，产量成倍增长。
After the experimental demonstration and investigation, this paper proposes that Guizhou is located in the subtropical zone and its natural conditions are suitable for the growth of tea trees. It is one of the tea origins and one of China’s major tea producing areas. However, the current level of yield is below one fourth of the national average . The results of the survey and the trial showed that the low-yielding tea plantations are large in size, under-inputted, extensively managed and poorly managed are the main reasons that affect the yield increase of tea. In the future, the focus of tea production should be on improving the existing tea plantation yield and tea quality. Cultivation of soil improvement, fertilizing tea plantation is to improve the basis for yield of tea plantation; at the same time, the use of renewable crown, rejuvenation of the tree, fertilizers, a reasonable stereotypes and prunes, timely picking, pest control, strengthen management and other comprehensive technical measures will enable low- Quickly revived and output multiplied.
