一、材料与方法试验的分布及设计的详细情况和其他有关资料见附录(本刊略)。不同试验所采用的冠接技术略有差异,试验1、2、3是按常规芽接法把树冠接在1.5～2年生的树干上;试验4—9是研究有关改进冠接技术的各种因素,以便最后应用于商业生产,内容包括研究顶蓬叶所处状态、树冠和树干组织的成熟度对冠接成活和失败的影响。试验8起初是一个商业胶园布置的一个冠接试验,由于冠接技术太差,
First, the distribution of materials and methods and design details of the test and other relevant information, see appendix (this publication). The crown technique used in the different experiments was slightly different. In the first, second, third and third experiments, the crown was connected to the 1.5 to 2 year old trunk according to the conventional sprouting method. The fourth to ninth experiments were conducted to study various factors For final application in commercial production, including the study of the state of the canopy, the effect of crown and trunk maturity on the survival and failure of the crown. Experiment 8 was originally a commercial crown park layout of a crown test, due to poor crown technology,
