在湿地松种子园营建的嫁接过程中,如何解决当前接穗不足的问题是个大问题。今年以来,我们观察到湿地松萌发新梢的部位是多方面的,不仅在主梢和侧枝的顶端、在轮枝的腋间可以抽出新梢,而且在一束针叶的中心,也同样会孕着芽苞,发育成新梢。根据这种情况,我们将枝条上的针叶束连着枝条上的皮层割下,嫁接在砧木上,使之萌发新梢,用以代替枝条作接穗嫁接的方法。经过试验,证明此法可行,我们把这个方法称为针叶束带皮贴接法。采用这个方法能节省大量接穗。1974年3月上旬,我们在1年生的植株上,削取带枝皮的针叶束,嫁接在另一砧木上,共嫁接了28株,到6月底检查,共成活了25株,其中已抽新梢形成了新植株的有22株
How to solve the current shortage of scions is a big problem during the grafting process of the wetland pine orchard. Since this year, we have observed that there are many aspects to the germination of new shoots of Pinus elliottii, not only at the tips of the shoots and branches, but also at the armpits of the branches of the branches, and in the center of a bunch of needles Pregnant bud bud, develop into a new shoot. According to this situation, we cut the branches of the needle bundle cuttings tied to the branches, grafted on the rootstock, so that germination of new shoots, instead of branches for the method of scion grafting. After testing to prove that this method is feasible, we call this method of coniferous belts tape affixed. Using this method can save a lot of scion. In early March 1974, on the one-year-old plant, we cut needled bundles of twigs and grafted them onto another rootstock. A total of 28 plants were grafted. By the end of June, we had a total of 25 surviving plants, of which The new shoots formed a new plant 22
