从结实的成年树选取生长健壮、胚芽饱满的一年生板条作插穗。长度为7～10厘米,具二节。插穗下切口紧靠节下0.5厘米处斜削成45°角,上切口在芽上方1厘米处,切口力求平滑。插穗基部用生长素处理,插入苗床深度为插穗的三分之二,随即浇足水,经常保持湿润。主要技术措施:在玻璃房内,用砖砌成高20厘米,宽1米,长4米的苗床,填入15厘米河沙、培养土或 Choose from robust adult tree growth robust, full of embryo annual plank cuttings. Length of 7 to 10 cm, with two. Close cut under the cut next section 0.5 cm beveled at a 45 ° angle, on the incision above the bud 1 cm at the cut for smooth. The base of the cuttings is treated with auxin, and the depth of the cuttings inserted is two-thirds of the cuttings, followed by watering of the foot and regular wetting. The main technical measures: In the glass house, with brick as 20 cm high, 1 meter wide and 4 meters long seedbed, fill in 15 cm river sand, soil or culture
