在海拔 80 0ｍ以上茶区 ,常规育苗的成活率和出圃率很低 ,主要原因是秋冬季容易遭受干旱和冰冻灾害。为了探索二高山茶区提高扦插育苗成活率和出圃率的途径 ,加快无性系良种推广步伐 ,鹤峰县国营走马茶场经过多年试验研究 ,总结出了覆膜免浇育苗技术 ,并取得了很好的应用效果。 At tea plantations above 80o meters above sea level, the survival rate and the nursery rate of conventional seedling raising are very low, mainly due to the fact that autumn and winter are vulnerable to drought and freezing disasters. In order to explore the way to improve the survival rate and yield rate of cuttage seedlings in two alpine tea areas and speed up the popularization of improved clones, the state-run Zhuma Chachang in Hefeng County, after many years of experimental research, summed up the technology of film-free nurturing seedlings and achieved good results The application effect.
