尽管对旨在使茶叶产量增加到3000千克/公顷的更新计划热情很高,但在斯里兰卡茶叶的产量仍只有1800千克/公顷。低产有各种各样的因素,包括只依靠1、2个无性系。用5、6个不同的。优良无性系混合更新可改善茶叶的品质和产量。对于山地茶树更新的策略是限制较耐寒而产量表现相对差的无性系,如DN,CY 9和TRI2025;种植地区要有某种程度的限制,而在其余的地区种植优良无性系,包括TRI2024、TRI62/9、
Despite the enthusiasm for an update program aimed at increasing tea production to 3000 kg / ha, the yield of tea leaves in Sri Lanka is still only 1800 kg / ha. There are a variety of low-yielding factors, including relying solely on 1, 2 clones. With 5,6 different. Good clonal hybrid update can improve the quality and yield of tea. The strategy for mountain tea plant regeneration is to limit clones that are less tolerant to relatively poor yields, such as DN, CY 9 and TRI 2025; to some extent in growing areas and to fine clones in the rest, including TRI 2024, TRI62 / 9,
