Ecological Adaptability of Three Tea Varieties of Echa Series Introduced into Hanzhong

为筛选适宜汉中地区栽培的茶树品种,引进了鄂茶1号、鄂茶5号和鄂茶8号3个茶树新品种,开展了连续6 a的适应性、适制性等综合性观测评价试验。结果表明:鄂茶5号和鄂茶1号在成活率、生长势、鲜叶产量、抗性和绿茶品质等方面的表现超过或接近对照品种福鼎大白茶,适宜汉中及陕南地区栽植;其中鄂茶5号综合表现最佳,为特早生品种,成活率高,抗性强,春茶小区产量高于对照42.67%,加工绿茶品质优;而鄂茶8号成活率低,生长势较弱,不适宜汉中地区栽植。

To screen suitable tea varieties for cultivation in Hanzhong area,three introduced varieties,Echa No.1,No.5 and No.8,were carried out a comprehensive observation and evaluation experiment on their adaptability and suitability for six consecutive years.The results demonstrated that the survival rate,growth potential,fresh leaf yield,resistance and green tea quality of Echa No.1 and No.5 were better than or close to the control FudingDabai,thus both of the two cultivars are suitable for planting in Hanzhong and southern Shaanxi.And Echa No.5,as a special early-growing cultivar with high survival rate and strong resistance,presented the best comprehensive performance;its spring tea yield per plot was 42.67%higher than the control's,and its green tea product was excellent in quality.However,the survival rate and growth potential of Echa No.8 were weak,which is not suitable for planting in Hanzhong area.
