冬枣是近年来发掘出来的稀有品种。为了大力开发这种新品种,在山东省果树研究所和山东省林校的帮助下,我们开展了冬枣绿枝扦插快速育苗技术的研究。经过3年的试验研究,达到了预期目的,为生产推广应用提供依据。1 材料和方法1.1 插穗及其处理于6月初取3～4年生冬枣的当年生枣头及枣吊为插条。枣头长20～40cm,粗0.6～0.8cm,保留顶芽及中上部分枝、叶片,剪除下部3～5cm的分枝。插穗下剪口落在半木质化部位。枣吊长20～25cm,粗0.3cm左右。枣吊一种处理是剪除基部2～4cm的叶片,保留顶尖;另一种处理是摘除顶尖2～3cm,剪除基部2～4cm的叶片。
Jujube is rare species excavated in recent years. In order to vigorously develop this new variety, with the help of the Shandong Provincial Institute of Pomology and the Shandong Provincial Forestry School, we carried out the research on the rapid nursery technology of the jujube green branch cutting. After 3 years of experimental research, it has achieved the expected purpose and provided the basis for the popularization and application of production. 1 Materials and methods 1.1 Cuttings and their handling Early in June to take 3 to 4 years old jujube head of the year and jujube hanging cuttings. Jujube head length 20 ~ 40cm, coarse 0.6 ~ 0.8cm, retaining the top bud and branches in the upper branches, leaves, cut off the lower 3 ~ 5cm branches. Cuttings cut under the half-lignified wood cuttings. Zaozao long 20 ~ 25cm, rough 0.3cm or so. Jujube hanging a treatment is cut off the base 2 ~ 4cm leaves, leaving the top; the other is the removal of the top 2 ~ 3cm, cut off the base of 2 ~ 4cm leaves.
