一、选择桥接有利时期,桥接在苹果树液流动后至停止流动前都可进行,但以春季四月廿日左右即萌芽开花期为最佳时期。此时树体生命活力最旺盛,桥接后伤口易愈合,成活率比较高。 二、精选优良接穗,接穗最好选萌芽力、成枝力低的品种。也可在本品种健康树上选取长50～60厘米,粗细适宜健壮充实的2年生无分枝的枝条。以外围光照较好的枝条为最好,内膛徒长枝不宜作接穗。最好随采随接。
First, choose to bridge the favorable period, the bridge can be carried out after the flow of apple tree liquid to stop before the flow, but in spring April 20 or so germination and flowering period is the best period. Tree vitality at this time the most vigorous, easy to heal wounds after bridging, the survival rate is relatively high. Second, the selection of fine scion, scion best choice sprouting buds, branches of low power varieties. Also available in the variety of healthy tree length of 50 to 60 cm, the thickness of suitable robust robust 2-year-old branches without branches. To peripheral lighting better branches for the best, only a long branch of the spike should not be made. With the pick the best pick.
