摘　　要：麻栎是云南滇中地区的本土树种。1999年以来,在云南牟定县启动实施的中德合作造林项目中采取云南松与麻栎混交的主要造林模式,在麻栎育苗过程中,采用普通的塑料袋育苗技术存在出圃前出现主根严重穿袋现象,造成了苗木出圃率和移植成活率较低。为此,开展了麻栎胚根切除技术及育苗用土施肥2种措施,在防止育苗穿袋方面取得了成功,并在中德合作云南二期造林项目中推广和应用3 193 hm2,采用麻栎胚根切除技术育苗,苗木合格率提高了25.70%,造林成活率提高了32%,取得了显著的经济和社会效益。Quercus acutissima is one kind of native plant in central Yunnan Province. Since 1999, mixed pattern of Pinus and Quercus acutissima has been taken as the primary afforestation model in second stage of Sino-German cooperation reforestation project in Muding County. By using ordinary seedling nurseries technique, the bags were usually punctured by Quercus acutissima seedlings root and the proportion of seedling and transplant survival rate are low. Therefore, Quercus acutissima radicle resection breeding technology and seedling formed fertilization techniques have been taken, effectively prevent the seedling root puncturing plastic bags, and those two techniques have been promoted and applied in second stage of Sino-German cooperation reforestation project, which achieved 193hm^2 afforestation. By using Quercus acutissima radicle removal technique, the seedling rate increased by 25.70% , the afforestation survival rate increased by 32% , and achieved remarkable economic and social benefits as well .
