高海拔区3个茶树品种生长特性的综合评价

Comprehensive evaluation of growth characteristics of three tea cultivars in high altitude tibet tea area

试验研究对象为‘蜀永808’‘中茶102’‘中茶302’3个茶树品种一年生实生苗,通过观察它们生长过程中的变化,对苗高、地径、一年生枝条的长度、粗度、叶片数等数据进行汇总和分析,通过隶属函数对其分析最终得出结论,对3个茶树品种生长特性做综合评价。结论表明:通过对比不同茶树品种实生苗的生理性状,3个茶树品种实生苗品质最优为‘蜀永808’,次之‘中茶102’,相对较差的是‘中茶302’;利用隶属函数法综合评价3个茶树品种实生苗的品质,表明‘中茶102’的隶属函数值最高,‘蜀永808’的隶属函数值次之,‘中茶302’的隶属函数值最低,通过分析3个茶树品种实生苗的数据结论表明,最适宜在林芝地区种植的品种为‘中茶102’。

One-year old plants of tea cultivars"Shuyong 808","Zhongcha 102"and"Zhongcha 302"were used to observe the physiological parameters of plant height,trunk diameter,and length,diameter and leaf number of one-year old branches.The data were analyzed by membership function method.Based on the physiological parameters,the seedling of"Shuyong 808"was the best,and that of"Zhongcha 102"was next,followed by"Zhongcha 302".The membership function analysis showed that the value of membership function of"Zhongcha 102"was the highest,followed by"Shuyong 808"and"Zhongcha 302".It was concluded that the most suitable tea cultivar for planting in Nyingchi district was"Zhongcha 102".
