摘　　要：目的:研究不同采收年限及采收部位对厚朴药材产量和商品性状的影响,为制定合理的采收期提供依据。方法:在厚朴规范化种植基地选取不同树龄的厚朴树,分别对其不同生长部位的药材样本,测定其鲜重、干重和厚朴皮厚度。结果和结论:认为树龄15年以上是厚朴适宜采收年限,树龄延长到20年对提高厚朴商品质量性状有利。厚朴树龄与药材产量、商品质量(皮厚)存在极显著的相关性,建立了厚朴药材产量和商品质量性状(皮厚)与树龄的预测模型。Objective： To establish the optimal harvest time of M. officinalis. Methods： Fresh weight, dry weight and thickness of different parts of its cortex were determined, which were choosed from different tree-ages of M. officinalis in GAP base. Results＆Conclusion： The optimal harvest time is at the age of 15 years, it is propitious to the commercial quality to extend the tree age to 20 years. There are very significant correlations between tree-ages and yields, commercial quality, and the prediction model based on these dates were established.
