| 摘 要： | 1974～2000年美国山核桃在云南省漾濞、永平、昌宁等地进行引种试验和扩大引种试验表明，该树种生长量以第7年最大，金华和绍兴品种结果多，产量高；山站2号和兴林13号各项丰产指标均低，株产量少；结实大小年明显，金华品种为2年一周期，绍兴为3年；与原产地浙江相比，品质较好；在中亚热带生长和开花结实表现很好。美国山核桃与国内外在良好管理条件下的产量和质量基本相同，适宜于云南省栽培。从而为云南省增添了一个新的经济林木树种，填补了核桃分布下限没有好的油料干果树种可供发展的空白。

| Abstract: | Introduce and extending experiment of Carya illinoensis were conducted in Yangbi, Yongping and Changning of Yunnan Province from 1974 to 2000. The results indicate that the trees of seven years old show the fastest growth. Jinghua and Shaoxing varieties bear the most fruits and have the highest yield. Shanzhan No.2 and Xinglin No.13 are on the contrary. There exists more fruiting year and less fruiting year. Normally, two years is a cycle for Jinghua variety and three years for Shaoxing variety. Comparing with those in native area Zhejiang, they show better in quality. And they show well in growing, flowering and fruiting in mid-tropical regions. Both quantity and quality of Carya illinoensis introduced to Yunnan are almost the same as those planting in good conditions at home and abroad. The introduce work has added a new economic forest species to Yunnan, and they can act as oil dry fruit trees distributing in the blank space of lower elevation of Walnut distribution. |
