为了提高扦插成活率,加速壮苗的育成,于1973—75年进行了一系列试验,以期对现行短穗扦插法有所改进,试验设计采用正交试验法,主要结果是:(1)研究出简便而有效的使用生长调节物质的方法。利用生长调节物质促进插穗发根,经三年试验,得出以50ppm2.4—D和30ppm 增产灵的水溶液,于剪枝前5—10日喷射母树,效果甚好;(2)采用二叶插比一叶插发根快、根系发育好、生长势强。二叶插的效果在发根初期最明显,因此应及时加强管理,以充分发挥二叶插的作用。经6个品系对比,不论大叶类或中叶类,二叶插的成活率与一叶插无明显差异。
In order to improve the survival rate of cuttings and accelerate the growth of strong seedlings, a series of experiments were carried out in 1973-75 in order to improve the current short spike cutting method. The orthogonal design was adopted for the experimental design. The main results are as follows: (1) A simple and effective method of using growth regulators. Using growth regulators to promote the cuttings of the cuttings, after three years of experiments, it was concluded that spraying 50 ppm2.4-D and 30 ppm Ganoderma lucidum aqueous solution on the 5-10 days before pruning sprayed the mother trees, the effect was very good; (2) Plug faster than the root inserted hair, root development, growth potential. The effect of two leaves plug the most obvious in the early hair root, it should promptly strengthen management, in order to give full play to the role of two leaf plug. After six lines of comparison, whether large leaves or middle leaves, two leaf plug survival rate and leaf plug no significant difference.
