沙地柏(Sabina vulgaris Antoine)又名臭柏、双子柏。原产内蒙、甘肃一带,垂直分布区于海拔200～2800米。是常绿匍匐灌木,它具有抗塞、耐旱和耐瘠薄土壤的特性,适应性很强,是良好固沙、护坡的水土保持树种。其枝叶可用作饲料、药材和燃料。为了绿化京郊荒山、荒滩、丰富造林树种,我们开展了沙地柏引种试验。但由于沙地柏球果的成熟度不良,(一年生有种仁的球果只占4％,三年生球果有12～30％含有种仁)。又因种子萌芽期间过长(一年之久)。因此,沙地柏播种繁殖困难。为了加速繁殖苗木,我们于1981年夏季进行了沙地柏嫩枝扦插试验。
Sabina vulgaris Antoine also known as Sabina, Gemini cypress. Native Inner Mongolia, Gansu area, the vertical distribution of 200 to 2800 meters above sea level. It is an evergreen creeping shrub that has the properties of resistance to water, drought and barren soil. It is very adaptable and is a good soil and water conservation species for sand fixation and slope protection. Its branches and leaves can be used as feed, medicine and fuel. In order to green Beijing suburbs of barren hills, wasteland, rich afforestation species, we carried out the introduction of sand cypress test. However, due to the poor maturity of the cypresses in the sandy land, only 4% of the annual kernels have seeds and 12-30% of the three-year-old cones contain seeds. Because of the seeds during the sprouting period is too long (one year). Therefore, sibiricus sowing breeding difficulties. In order to speed up the breeding of seedlings, we carried out in the summer of 1981 Sabina tendew test.
