摘要
厚朴伐桩有很强的萌蘖能力，在生长季节采伐也能得到满意的萌芽更新效果，每个伐桩可萌发 １ ～ ７ 个萌芽条，７ 年生厚朴矮林的树干与树枝鲜重达 ６０．２ ｔ·ｈｍ－２，平均净生产量为 ８．６ ｔ·ｈｍ－２·ａ－１，表明厚朴完全适宜矮林经营。伐桩高度对萌芽条数量、矮林生长影响不大；伐桩萌芽条数量越多，矮林生长越好。
Magnolia officinalis and M. officinalis ssp. biloba have strong sump shoot capacity, even felled in growing season. There were 1-7 shoots in each sump, and fresh weight of 7-year Magnolia coppice trunk and branch reached 60.2t/hm2, the mean net yield 8.6 t·hm-2·a-1, indicating suitable for coppice management. The sump height had no significant effect on shoot amount and growth. The more sump shoot, the better growth of coppice.
