枝接是山楂嫁接的一种主要方法。它的特点是接后长得快,当年可成苗。在砧木粗大,砧、穗不易离皮时宜采用此法。也用于苗圃上年芽接未成活的补接以及野生砧木的嫁接。山楂枝接应抓好以下几个主要环节。一.枝接时期山楂枝接直在砧木芽已萌动,接穗尚处于休眠状态时进行。一般说来,切接、劈接宜在清明前后离皮前进行,插皮接、腹接宜在4月中下旬至5月上旬砧木离皮时进行。二.接穗的采集接穗应选择当地推广的优良品种,从生长健壮、无病虫害的植株上剪取发育充实的枝条。内膛徒长枝、细弱枝不宜选做接穗。采穗时期以芽膨大前为宜。采下后每50或100枝捆成一捆,贮放在菜窖中,基部埋好湿沙待用。三.枝接方法
Branching is a major method of hawthorn grafting. It is characterized by pick up fast, then can be a seedling. In the rootstock coarse, anvil, spike is not easy to use this method from the skin. Also used in nursery budding last year, unpowered pick-up and grafting of wild stock. Hawthorn branch should do a good job following several major links. A sticking period Hawthorn branches straight in the rootstock bud has sprouted, the scion is still in hibernation. In general, cut access, cleavage should be clear before and after the skin from the cut, cutaneous access, abdomen should be in late April to early May when the rootstocks from the skin. Second, the scion collection scion should choose the local promotion of fine varieties, from robust growth, plant diseases and insect pests on the development of well-developed branches. Only a long branch of the hearth, thin branches should not be selected scion. Scavenging buds before the enlargement is appropriate. After the harvest of 50 or 100 bundles tied into a bundle, stored in the cellar, the base buried good wet sand stand. Three branches method
