三种不同春季高接换种方法在温州蜜柑上的比较试验

Comparative experiment of three different spring high-replacement methods on Wenzhou mandarin

研究3种不同春季高接换种方法对接芽成活率、枝稍萌发数量、新梢生长量、树冠及产量的影响。结果表明,3种不同高接方法对接芽成活率无明显影响,但对枝稍萌发数量、新梢生长量、树冠及产量有差异。锯头高接换种能明显增加树冠高度和冠幅,提早结果。锯头双芽切接与锯头单芽腹接相比,产量差异显著。

The effects of three different spring high-replacement methods on the survival rate of buds,the number of germinations,the growth of new shoots,the crown width and yield were studied.The results showed three different high-replacement methods had no significant effect on the survival rate of buds.However,there are differences in the number of sprouts,the growth of new shoots,the crown and the yield.The sawing head height could increase the crown height and crown width obviously.Compared with sawing head single bud ventral grafting,the yield difference was significant.
