核桃压条繁殖是最近试验成功的。方法是:将核桃良种无性繁殖苗定植在水肥条件较好的地方(可与建立核桃良种采穗圃结合进行),实行丛状或低干整形,离开树干1米左有采用多侧枝扇形整枝技术,使之尽量多发侧枝,8、9月份新梢停止生长后(转入加粗生长),离开树干1米左右环挖40—60厘米深的沟,把核桃枝(一年生枝生根优于二年生枝)呈弓形压入沟内并回定,把压入土中的各条侧枝,用铁丝环拧至微陷入皮层(不要使 Walnut streak propagation is the recent successful trial. Method is: walnut seed asexual seedlings planted in water and fertilizer conditions better place (with the establishment of walnut seed breeding garden combined), the implementation of plexiform or low-dry shaping, leaving the trunk 1 m left with a multi-branch fan-shaped pruning technology , So that as much as possible lateral branches, in August and September to stop the growth of new shoots (into bold growth), leaving about 1 m away from the trunk ring dig 40-60 cm deep, the walnut branch (annual branch superior to biennial branches ) Was arched into the ditch and set back, the pressure into the soil of the collateral, with a wire ring screwed into the micro-into the cortex (do not
