美国林木种苗培育技术现状及启示

美国林木苗圃在种苗培育上有着较好的技术和经验, 作者以1992年掌握的美国种苗信息为基础, 对20年后美国林木苗圃主要育苗技术情况进行分析和综述。其中主要介绍美国东南部和西北部地区近15个林木种苗生产相关企业及研究所的实用技术和技术推广情况, 讨论美国林木种苗行业协会和技术推广专家在育苗技术推广中的作用和形式, 提出了技术创新、苗圃分类经营、政府引导和产学研紧密结合等建议, 以期为我国的林木种苗产业发展提供借鉴。

Nursery Techniques in the USA and Their Inspirations

Forest nurseries in the USA have feasible technology and experiences with respect to seedling cultivation. Based on the information collected by the authors in 1992, the general seedling cultivation technologies used by American forest nurseries in recent years were reviewed and analyzed. We mainly introduced the applied techniques and their extension used by around 15 forest nursery enterprises and institutions in the southeast and northwest America, and discussed the functions of America Nursery Association and its technology extension mode. Finally, some suggestions were made for the improvement of Chinese nursery industry, i.e., technical innovation, nursery classification management, government guidance and the combination of industry, university and research institute.
