臭柏(Sabina vulgaris Ant)为常绿匍匐针叶灌木,根系发达,枝叶茂密,耐干旱、瘠薄,喜沙埋,抗风蚀,是我区防风固沙和水土保持的重要树种之一,也是城市绿化和布设盆景、生篱的优良树种。臭柏枝叶富含油脂,还是很好的薪炭林。多年来,由于臭柏繁殖困难,使这一树种的发展受到限制。1982年以来,我们围绕臭柏种子发芽困难、需时较长、出苗不整齐等几个问题,在不同种子处理、不同播期等方面进行了试验,使臭柏播种育苗获得良好效果。现介绍如下:一、育苗地情况育苗地位于榆林城西沙,为1980年引水拉沙新修的沙地,地面垫黄土厚15厘米,pH 值为8.14,土壤肥力较低,地下水位11
Sabina vulgaris Ant is an evergreen creeping coniferous shrub with developed root system, dense foliage, drought resistance, infertility, hi sand buried and wind erosion resistance. It is one of the important tree species for windbreak, sand fixation and soil and water conservation in our district, And layout of bonsai, hedgerow fine tree species. Sabina vulgaris leaves rich in fat, or good firewood forest. For many years, the development of this tree species has been limited due to the difficulty of breeding Sabina vulgaris. Since 1982, we have carried out experiments on the problems of seed germination, long time of needling, uneven emergence and so on. We have conducted experiments on different seed treatments and different sowing dates to achieve good results in sowing seedlings of Sabina vulgaris. The introduction is as follows: I. Situation of Nursery Area The nursery area is located in Xisha, Yulin City. It is a sandy area newly rebuilt in Laosha in 1980 with a loess thickness of 15 cm and a pH value of 8.14. The soil fertility is low and the groundwater level is 11
