【摘要】 对我国特有树种、重要中药材资源厚朴开展环利与半环剥，以及林分郁闭度大小、剥皮季节、剥皮后用纸包扎与否对再生新皮的影响等内客的试验，并进行试验后观察与再生皮、原生皮成份的测定，结果表明，只要正确掌握厚朴剥皮技术，厚朴剥皮2～3年，再生皮即可达到原生皮厚度，3～5年后再生皮的药用成份合量基本达到原生皮的水平。此项技术推广，将对改变砍树剥皮为留树轮利的作业方式、为保护厚朴资源、提高产区的经济效益和生态效益将产生很大的影响。更多还原

【Abstract】 Experiment carried out on annular skning and semi-annular skining of Magnolia officinalis, an endemic tree species and an important medicine plant, on effect of stand closure,skining period and packing with paper on reclamation. Observations and determination of relamating hark and original hark resulted that if skining techniques of M.officinalis were mastered, reclamating bark would reach the thickness of original one 2～3 year after skining,and medicinal comPOnent of reclamations would nealy the same as original ones. The extension of these techniques would, be important for protecting M. officinals resources, increasing economic and ecological bent fit in the production area.更多还原
