为建立云南松无性系种子园,1972年以来,我们曾多次进行了云南松嫁接试验。试验过程中,在学习省外兄弟单位成功经验的基础上,我们提出了一种操作简便的嫁接方法-——侧劈接。几年来的试验结果表明,用此种方法嫁接,成活率比髓心形成层接、瓶接、侧接等方法都高。1973年7月的一次嫁接,成活率达到90％;1974年和1975年的嫁接也收到同样良好的效果。现将这种方法的操作过程作一介绍。1.接穗和砧木的处理在已采回的接
To establish the clonal seed orchard of Pinus yunnanensis, we have conducted many trials of Pinus yunnanensis grafting since 1972. During the experiment, based on the successful experiences of brothers and sisters outside the province, we proposed a simple and easy grafting method --- side splice. Several years of test results show that grafting with this method, the survival rate than the pith formation layer, bottle, side and other methods are high. In July 1973 a graft, the survival rate of 90%; 1974 and 1975 grafts also received the same good results. Now this method of operation to make an introduction. 1.
