嫁接可以保持优树的优良遗传品质,并能提早结实,矮化树冠等。为了探讨杉木嫁接种子园营造的方式和方法,我场1966年春秋两季在苗圃地嫁接杉木330株,成活率达97%。春季嫁接的当年接穗平均高生长45厘米,最高达70厘米;平均粗生长0.9厘米,最粗达1.2厘米;平均冠幅50厘米,形成2—3轮枝。现将嫁接技术介绍如下,供参考:
Grafting can maintain excellent tree superior genetic quality, and can be earlier, dwarf crown. In order to explore the ways and methods of seedling planting of Chinese fir grafting, 330 fields of Chinese fir were planted in the nursery of Spring and Autumn in 1966 with a survival rate of 97%. In the year of spring grafting, the scions averaged 45 centimeters high and a maximum of 70 centimeters; the average coarse growth was 0.9 centimeters and the maximum was 1.2 centimeters; and the average crown was 50 centimeters, forming 2-3 branches. Grafting technology now introduced as follows, for reference:
