景宁白茶套罩嫁接法试验

［目的］确定景宁白茶的最佳嫁接时间段和不同品系间嫁接的难易程度。［方法］分别在秋、春和夏季采用套罩保湿法和随机区组排列对景宁白茶进行嫁接试验。［结果］景宁白茶在春、夏和秋季的嫁接成活率在72.0%-94.0%之间，夏季的平均成活率与保存率分别为91.2%和81.3%，春季和秋季的平均成活率分别为80.0%和82.0%，秋季的平均保存率仅为25.7%。秋季和春季嫁接景宁白茶的平均株高约为56.2和47.1 cm，平均冠幅约为10 cm × 10 cm。不同品系景宁白茶的嫁接成活率和保存率分别为79.1%-87.8%和50.7%-57.6%；白玉1号的成活率最低，为79.1%；坟山2号的成活率最高，达87.8%。三枝树品系的平均株高最高和冠幅最大。白玉1号和白玉2号的平均株高分别为三枝树品系的77.0%和85.8%。［结论］套罩法嫁接景宁白茶，夏季的成活率和保存率最高，品系间的成活率和保存率差异不显著，但生长量相差较大。
