采用播种法培育实生砧然后嫁接良种，是目前国内外最为快速有效的枣苗繁殖技术措施。现将该项技术总结介绍如下。互种子的采集由于大枣含仁率仅为2％～3％，因此通常用酸枣种培育实生砧。陕北地区种子的采集时间一般在10月中下旬酸枣叶色变黄时进行。采集的种子必须是充分成熟 Cultivation of seedlings by planting sowing grafting and then grafted elite, is the most rapid and effective at home and abroad Zaomiao propagation techniques. The technology is summarized below. Mutual seed collection Since jujube kernel rate is only 2% to 3%, so usually jujube seedling cultivation of anvil. The collection time of the seeds in northern Shaanxi is generally carried out in the mid to late October when jujube leaf color turns yellow. The collected seeds must be fully ripe
