采用3种不同的方法对杜松种子进行催芽处理实验,结果表明:相比于混砂催芽方法和温、冷水交替浸种催芽法,采用热水浸种、变温催芽方法处理的种子,播种后出苗时间短,苗齐,其1年生幼苗高生长、地径以及壮苗数量都较高。在育苗上,热水浸种、变温催芽方法要好于其它两种方法。

Three different methods was used on the seed germination experiments of Juniperus rigida Sieb. et Zucc. , The results showed that ： compared to the method of mixing sand seed germination and the warm - cold water soak the seeds, u- sing hot water soaking, variable temperature approach of seed germination, the seedlings unearthed rapid and neat, the height growth, diameter and the number of excellent seedlings of the 1 - year seedling were higher, In the nursery, the hot water soaking, variable -temperature germination method was better than the other two methods.
