| 摘 要： | 本文在怀宁县皖河滩地进行了4个杨树品系：湘林77、80、90和南林95的引种育苗试验，供试面积6．67hm2；2008年5月20日至10月20日，在不同品系杨树苗木中随机抽取一个标准行苗木，每隔15天调查一次地径、苗高，以进行不同杨树品系苗木生长规律与对比试验研究。结果表明：杨树4品系地径、苗高生长均随时间呈线性增加；不同品系苗木地径和苗高生长差异显著，南林95和湘林80表现最佳。

| Abstract: | In this paper seedling-raising experiments were carried out with 4 introduced poplar varieties including Xianglin 90, 85, 77 and Nanlin 95 on Yangtze River marshlands with a selected area of 6.67 hm2 in Huaining county of Anhui Province from May 20 to October 20, 2008. A-standard-line seedlings were taken in random fi：om each of the 4 poplar varieties, and their basal diameters and heights were measured and recorded every 15 days for the study on the growth patterns and contrast experiments of the 4 poplar varieties. The results showed that the seedling basal diameter and height growth of the 4 varieties showed linear increase with time, and had significant differences among different varieties with the seedlings of Nanlin 95 and Xianglin 80 being the best. |
