桧柏是很好的绿化树种,但由于种源缺乏,繁殖速度受到影响。为提高繁殖率,我们于1984年冬开始,进行了两年的越冬前桧柏嫩枝扦插试验,效果较好,方法简单,成活率高。一、圃地选择选背风处作苗床,挖成长5-10米、宽1.5-2.5米、深0.6-0.8米的沟。为防止苗床两壁土壤脱落,可将苗床做成横断面为上宽下窄的倒梯形,使其两壁形成75-80度的斜坡;也可在苗床两壁砌砖,使其与地平面垂直,床上下宽度相等。床底铺15厘米厚的沙土做插壤 Juniper is a good afforestation species, but due to lack of provenance, breeding speed affected. In order to improve the breeding rate, we started the winter in 1984, carried out two years before the winter cypress softwood cuttings test, the effect is better, the method is simple, high survival rate. First, select the leeward garden to choose seedbed, digging grow 5-10 meters, 1.5-2.5 meters wide, 0.6-0.8 meters deep ditch. In order to prevent the soil on the two walls of the seedbed from falling off, the seedling bed can be made upside down trapezoid with wide upper and lower narrowing so that the two walls form a slope of 75-80 degrees; Vertical, bed width equal. 15 cm thick sand bed at the end of the bed to do plugging
