摘要
概述了我国引种薄亮山核９０余年所经过的自发引种、大量引进及无性系选择、良种引进３个阶段后，揭示了我国薄壳山核桃起步迟、发展慢，至今尚未形成高品生产的主要原因是①结实迟、产量低②资源贫乏、品种单一③良种苗木难于繁殖④病虫众多、管理困难，进而提出今后进一步发展薄壳山核桃的对策。
Descriptions on over 90 years introduction history of China illinoensis in China with 3 steps showed that the causes of late start、slow development. no commercial production up to now were late bearing,low yield;poor resources and varieties;difficult propagation of fine seed; many insects and disease which were difficult to control. Countermeasures for further development of C. illinoensis were proposed.
