利用无性育种学的基本原理,选择优良品种根蘖苗,通过归圃技术,培育大批无性系良种枣苗,以满足枣树发展对苗木的需求。通过多年的科研实践,掌握了枣归圃苗的新根萌发、苗高生长,地径生长的规律,从而为科学培育枣树优质归圃苗,提供了理论依据。现将研究结果,简述如后,供林业科技及育苗工作者参考。一、新根萌发研究枣归圃苗的新根,多由根蘖苗拐根上的 Utilizing the basic principles of asexual breeding, we select the best variety of tillering seedlings and nurture a large number of jujube seedling of clonal germplasm through nursery garden to meet the demand of jujube tree development. Through years of scientific research, we have grasped the rule of germination, height growth and diameter growth of new roots of jujube seedlings, which provided the theoretical basis for scientific cultivation of jujube quality nurseries. Now the research results, outlined later, for forestry technology and nursery workers reference. First, the new root germination research jujube Nursery seedlings of new roots, mostly by the root tillering Shui root
