1　插条的采集从优良品种、单株、生长健壮而又丰产的母株上采集。采集枝龄在1～2ａ生,枝条粗度为0 5～1ｃｍ的营养枝,枝条上的枝刺多,因此用这类枝条育苗发根多,成活率高。采集插条的时间,一是秋冬季落叶后、封冻前;二是春天3月份芽萌动前。枝条采集后分清品种,100根打捆,拴上 1 insert collection from the fine varieties, single plant, robust growth and high yield of the mother plant collection. Collecting vegetative shoots with branches of 1 ~ 2a in diameter and with branches of 0 5 ~ 1 cm in diameter, many branches on the branches are collected. Therefore, the seedlings of these branches have more hair roots and higher survival rate. Collection cuttings time, first autumn and winter leaves, frozen before; the second is the spring in March Bud sprouting before. Branches collected after the classification, 100 bundles, tied
