以刺五加苗、短梗五加苗、红毛五加为试材,分别在大通县、互助县、西宁市进行引种栽培试验,通过3年对3种五加的成活率、物候、冠幅、树高、地径等生长指标观测,研究不同试验地对3种五加的引种栽培表现。结果表明:引种的3种五加在试验地均能完成正常的开花结果等生育期,引种驯化初步成功;不同试验区,物候期及各项生长指标发生较为明显变化。3种五加在同一地区物候期基本表现相似,但略有不同。3种五加可在青海西宁地区及大通河流域的主要林区根据实际需要选择栽培。
The experiment was conducted in Datong County, Huzhu County and Xining City, respectively. The survival rate, phenology, crown Width, height, diameter and other growth indicators observed to study the different test sites on the introduction of three kinds of five-plus performance. The results showed that the introduced three kinds of five plus plants could all complete the normal flowering stage and other growth stages. The introduction and domestication were initially successful. The phenological stages and the growth indexes varied significantly in different experimental areas. The phenophases of the three species in the same area performed basically similar, but slightly different. Three kinds of five plus can be selected in Xining, Qinghai and the major forest areas of Datong River Basin according to actual needs.
