马尾松无性繁殖目前除用嫁接方法外尚无其它有效方法。随着大面积良种基地的建立,嫁接已成为无性系种子园营建的主要方法。但是,马尾松嫁接成活较其它树种难度大,往往因为嫁接成活率低而赔误建园工程顺利进行。我们经过几年来反复试验探索,发现“小砧嫩梢嫁接法”比“大砧老枝嫁接法”有较多的优点: (1)能大幅度提高成活率、保存率(成活率80％以上,保存率100％): (2)穗条丰富,无针叶,蒸腾量小,方便保鲜运输; (3)当年可解绑剪砧,接穗继续生长,当年可形成独立嫁接株; (4)不留或少留哺养枝,方便管理,节约成本;
Clonal propagation of Pinus massoniana Currently there is no other effective method except grafting method. With the establishment of a large area seed base, grafting has become the main method for the construction of clonal seed orchard. However, the grafting of Pinus massoniana is more difficult than that of other species of grafting, and the project of losing money and building gardens is often carried out smoothly due to the low survival rate of grafting. After several years of trial and error, we found that “grafting of small anvil shoots” has many advantages over “grafting of old grafted grafts”: (1) it can greatly improve the survival rate and the preservation rate (the survival rate is over 80% , The preservation rate of 100%): (2) rich spikelets, needle-free, small amount of transpiration, easy preservation transport; (3) that year can be uncoupled shear anvil, scion continue to grow, Stay or stay Feeding sticks to facilitate management, cost savings;
