| 摘 要： | 半干旱地区不同立地条件臭柏造林试验结果表明：无灌溉条件下，雨季和秋季是臭柏造林的适宜季节；造林成活率和保存率分别达７５．８％和６７．８％以上。造林时风沙土０～６０ｃｍ土层内平均含水率以３．４％～４．１％为宜，否则成活困难。臭柏造林当年生长量不足６．０ｃｍ，第三年生长加速，生长量为造林当年的３～４倍，并接近天然臭柏群落的新枝年生长量。

| Abstract: | s: Under different
site conditions in the semiarid region,the silvicultural experiment of Sabina vulgris revealed
that rainy season and Autumn are a seasonable time for Sabina vulgaris without irrigation
system,and a survival rate is up to more 75.8 percent and a conservation rate is up to more 67.
8 percent.When Sabina vulgaris is planted,the average moisture percentage of aeolian sandy
soils upper layer 0-60cm deep had better be 3.4-4.1 percent,otherwise it is difficult to
survive.The quantity of apical growth on the Sabina vulgaris is not more than 6.0cm in the first
year.The apical growth speeds up in the third year.Its quantity of apical growth is three or four
times as much as the first year's.It is near the annual quantyty of apical growth of new
branches of WTBX]Sabina vulgaris natural communities.\=\ \ |
