3个茶树双无性系品种种植试验初报
|
摘要
本试验将S-4等3个双无性系茶树品种种植在长沙等4个具有湖南区域代表性的地点,鉴定其出苗率、生长势、抗旱抗寒能力和适应性。结果表明:3个双无性系品种的出苗率、生长势、适应性均较对照品种保靖黄金茶1号优。出苗率,以吉首的S-6为最佳,达96.61%;生长势,吉首的S-6和新化的S-8均优于长沙3个双无性系品种及三地对照种;抗旱抗寒能力,3个双无性系品种在长沙、吉首和新化三地均为强,优于对照。
In this experiment,three double-clonal tea tree varieties,such as S-4,were planted in four representative sites in Hunan,including Changsha,to identify their emergence rate,growth potential,drought resistance and cold resistance and adaptability.The results showed that the emergence rate,growth potential and adaptability of the three double clones were better than that of the control variety Baojing Golden Tea No.1.The emergence rate of Jishou was the best with Jishou's S-6,reaching 96.61%; the growth potential,Jishou's S-6 and Xinhua's S-8 were better than Changsha's three doublefree varieties and three-land control; drought resistance and cold resistance The three double-free varieties were strong in Changsha,Jishou and Xinhua,which was better than the control.
