当前营建落叶松无性系种子园,主要应用髓心形成层贴接法。此法虽然具有技术简单,操作容易,成活率高,不伤砧木等优点,但它属于一种枝接法,缺点是条穗利用率低。为了提高优树的繁殖系数(即种条增殖的倍数),以便用少数质量特别高的优树,建立更多的优质种子园,我们试验用芽接法嫁接落叶松,两年共试验了五种方法,其中马耳形芽接法比较成功,收到了良好的嫁接效果。现将这项试验研究工作进行初步小结。由于时间较短,水平所
The current construction of larch clonal seed orchard, the main application of pith formation adhesion method. Although this method has the advantages of simple technique, easy operation, high survival rate and no injury to rootstocks, it belongs to a kind of sticking method with the disadvantage of low utilization rate of the ear. In order to increase the reproductive coefficient (ie multiples of seed multiplication) of superior trees in order to establish more high-quality seed orchards with a few superior trees of exceptional quality, we experimented with grafting of larches by budding and tested five Method, which malt budding method more successful, received a good grafting effect. Now this pilot study conducted a preliminary summary. Due to the shorter time, the level of
