近年来,我国新茶园扩展相当迅速,但低产茶园仍占较大的比例,单产低,品种混杂,不适应现代生产的要求。综观茶叶发展的趋势,今后应以稳定面积,提高单产,提高质量和提高经济效益为主攻的方向。当前当务之急是有计划、有步骤地加速改造低产茶园,其中部分经济效益低的茶园应换种改植优良无性繁殖系品种。茶树短穗扦播是无性繁殖方法,它的繁殖系数大,发根迅速,成活 In recent years, the expansion of new tea plantations in China has been quite rapid, but low-yielding tea farms still occupy a large proportion, with low yields and mixed varieties, which are not suitable for the requirements of modern production. Looking at the trend of tea development, the future should be based on a stable area, increase yields, improve quality and improve economic efficiency as the main direction. The immediate top priority is to speed up the transformation of low-yielding tea gardens in a planned and step-by-step manner. Some of the low-cost tea gardens should be replanted with finely cloned ones. Short-spike sowing tea tree is asexual reproduction method, its coefficient of multiplication, hair root quickly, survive
