柏树树形美观,适应性较强,是荒山造林和庭园绿化的重要树种.为了加速柏类繁殖,我们选择了新引进的柏木属(CupressusL.)中的墨西哥柏(C.lusitanica)的 5个不同种源(西班牙、危地马拉、肯尼亚①、肯尼亚②、肯尼亚③);绿干枯(C.arizonica)的2个种源(美国亚利桑和南美);西藏灵芝巨柏(C.ginantea)和浙江垂柏(C.funebris),以及圆柏属(Sabina spach)中的铅笔柏(S.virginiana)和桧柏(S.chinensis)的一些不同类型,在1984 年冬至85春季进行了电热温床扦插育苗技术的研究,现将结果报道如下.
Cypress is beautiful in tree shape and strong in adaptability and is an important tree species for afforestation and garden afforestation in barren hills.In order to speed up the breeding of cypresses, we chose 5 new C.lusitanica from Cupressus L. Different provenances (Spain, Guatemala, Kenya, Kenya2, Kenya3); 2 provenances of C.arizonica (Arizona, South America); C.ginantea (Tibet) C.funebris, and S.virginiana and S.chinensis in the Sabina spach were planted in the electric hotbed cuttings in the winter solstice in 1984 until spring 85 Technical research, the results are reported below.
