摘　　要：培育优质黄菠椤用材林的配套技术研究结果表明 ,采种母树林、种子园、雄性无性系采穗圃其子代遗传增益分别为 5 % ,1 0 %～ 1 5 % ,1 2 .7%～ 1 8.5 % .最适宜生长立地条件是排水良好、土层肥沃的阴坡山下部缓坡地带 ,其生长量比对照提高 1 9.1 % .黄菠椤最佳混交树种为落叶松 ,混交方式为行间混交 ,造林密度为 5 0 0 0株 /hm2 .适宜的郁闭度为 0 .5 .平茬最佳季节为冬季 ,其萌发率为 63% ,平茬部位是根际下部 ,最佳年龄为 3～ 5年 .The results showed that filial genetic gain of parent stand, breeding garden and male clones is 5 percent, 10～15 percent, 12.7～18.5 percent respectively. The best site condition is the shade of low pitch which is well drained and rich in soil layer, its growth improved 19.1 percent than control. The best mixed seed of Phellodendron amurense Rupr.is larch, its mixed mode is inter row, its forestation density is 5 000 plants per hectare. The suitable shade density is 0.5. The best season of stump is autumn, its germinal is 63 percent, the stump position is the lower position of rhizosphere, and the best age is 3～5 years.
