摘要
通过对5个铅笔柏种源造林试验表明:在引进的5个铅笔柏种源中,造林初期表现为LA种源最好,TX种源最差,各种源生长量高低排序为LA>SD>NE>MO>TX;铅笔柏造林以容器苗成活最好,达到99.17%;铅笔柏适应性较强,在温暖湿润、土壤条件较好的条件下,生长较快;与乡土树种相比较,当年生长量油松>铅笔柏>侧柏。
Based on the afforestation trial of 5 kinds of provenances of Sabina virginiana, it is found that the provenance of LA is best among them, whereas the one of TX is worst, they growth situation of all provenances of Sabina virginiana are ranged as LA>SD>NE>MO>TX from high to low in the initial stages of afforestation. The rate of survival is over 99.17% in container cultivation, which shows that it is adapt to container cultivation. Sabina virginiana has a great adaptability, and has a good growing state in warm, humid natural environment. Compare to the local plants, the growth situation are ranged as Pinus tabulaeformis Carr> Sabina virginiana>Platycladus orientalis from high to low.
