广东地处热带、亚热带,风土条件得天独厚,宜栽培半乔木型的大叶种茶树。从五十年代中后期开始,先后有韶关、海南、湛江、肇庆、佛山等地区引种了云南大叶群体种。从各地的生产实践来看,该品种普遍表现出速生、高产、优质等优良性状,深受各生产单位的欢迎。但各地的单产水平尚不够高,远远未能将优越的自然条件和良种的生产潜力充分发挥出来,特别是春茶产量偏低,平均仅占年产量的10～20％,直接影响全年产量的提高。据报道,重点产茶省区春茶都占年产量的40～50％,这与该省春<夏<秋(冬)的产量分布比例正好相反。本文试就如何提高大叶种茶树春茶产量问题,谈一些不成熟的看法。一、春茶低产的原因 Guangdong is located in the tropical and subtropical areas, blessed with unique terroir, should cultivate the semi-arborvitae big-leaf tea plantation. From the mid and late 1950s, Yunnan Province has successively introduced species of big leaf foliage from Shaoguan, Hainan, Zhanjiang, Zhaoqing and Foshan. From all over the production practice point of view, the species generally showed fast-growing, high yield, high quality and other fine traits, welcomed by the production units. However, the yield per unit area is not yet high enough, far from being able to give full play to the superior natural conditions and the potential for seed production. In particular, the yield of spring tea is relatively low, accounting for only 10-20% of the annual output, which directly affects the whole year Increase in production. According to reports, the key tea-producing areas in spring tea accounted for 40 to 50% of annual output, which is the province of spring
