恩施地区板栗芽接及其管理的时间效应

Castanea Mollissima Mud Grafting Technology in Enshi Prefecture and Its Time Effects of Management

春季和秋季进行板栗芽接试验,分别测验不同嫁接时间、春季嫁接不同时间剪砧和秋季嫁接不同时间解绑对嫁接成活率的影响,结果为:嫁接时间对板栗芽接成活率具极显著影响,秋季嫁接成活率高于春季嫁接成活率,在恩施秋季最适宜的芽接时间为9月上旬嫁接;剪砧时间对板栗嫁接成活率影响显著;解绑时间对板栗秋季芽接成活率影响不显著,影响接穗发芽率和发芽时间.

The experiment of castanea mollissima bud grafting is conducted in spring and autumn, including different time of the grafts, the influence of survival rates in pruning rootstock at different period to spring grafting and in unwrapping at different period to autumn grafting. The conclusion is as follows：The grafting time has an obvious effect on the survival rates of the castanea mollissima bud ; the survival rates in autumn are higher than in spring; the suitable time in autumn to bud grafting is early September,the pruning rootstock time has an obvious effect on the survival rates of castanea mollissima grafting; the unwrapping time has no obvious effects on the survival rates, but it affects the scion germination rates and the time of germination.
