白皮松是我国稀有珍贵树种之一,近年来它的观赏价值越来越受到人们的重视,而国内目前育苗仍处于传统的播种式,速度慢,出圃晚,对于幼龄林,结实量少的更显种苗奇缺。为此,我们于1985年进行扦插育苗试验,经5年努力,取得了平均成活率50.95%的成效,现将试验汇总如下。1 试验方法(1)试验设不同母树龄(4、10、18～20年)、不同枝龄(1、2、3年)、不同插壤(田土、河沙、(石至)石、森林土)、不 Pinus bungeana is one of the rare and precious tree species in our country. In recent years, its ornamental value has drawn more and more attention. At present, the seedling growing in China is still in the traditional sowing mode, which is slow and slow. Significant lack of seedlings. To this end, we carried out cuttage nursery trials in 1985, after five years of hard work, achieved an average survival rate of 50.95% of the results, the test is summarized below. 1 Test methods (1) The experiment set the different age (4, 10, 18 to 20 years), different branch ages (1,2,3 years), different soil intercalation Soil), no
