柞树用于柞蚕养殖历史悠久,但优良的辽东栎和麻栎目前母树林很少,育苗用的种子来源日趋减少。为寻找繁殖柞树的新途径,我们于1977年冬开始用扦插方法繁殖柞树,生根率可达60％以上,效果较好。现将试验结果简述于下: 一、材料与方法 1.插穗及其处理选用蚕场和苗圃里不同年龄的辽东栎、麻栋、蒙古栎、栓皮栎等的嫩枝及硬枝。将采集的枝条,随即浸在清水中,插前将嫩枝剪成12(硬枝10-25)厘米,两端留生叶的节,分别进行不剪叶、剪叶1/3、剪叶1/2三种处理,并将插穗基部放在浓度为25、50、100、200ppm的生长素中分别浸泡2、4、6、12、24小时及将插穗基部沾上Ⅲ号粉剂(IBA+NAA+(NH_4)_2SO_4)等处理,清水为对照。 2.扦插基质
Oak tree for tussah breeding for a long history, but excellent Quercus liaotungensis and Quercus few mother trees, seedling sources used to reduce. In order to find a new way to propagate oak tree, we started to propagate the oak tree by cutting method in the winter of 1977, the rooting rate can reach more than 60%, and the effect is better. Now the test results are briefly described below: I. Materials and Methods 1. Cuttings and their treatment Twigs and hardwoods of Quercus liaotungensis, Stirrup, Quercus mongolica and Quercus variabilis were selected from silkworm and nursery. Will be collected branches, then immersed in water, before cutting the twigs into 12 (hard branches 10-25) cm, leave the leaves at both ends of the festival, respectively, not cut leaves, cut leaves 1/3, cut leaves 1/2 three treatments, and the basal parts of the cuttings were immersed for 2,4,6,12,24 hours respectively in the auxin with the concentrations of 25, 50, 100, and 200ppm, and the basal part of the cuttings was dipped into the powder of the third grade (IBA + NAA + (NH_4) _2SO_4) and other treatments, water as a control. 2.
