摘　　要：[目的]研究不同种植密度对重齿毛当归干物质积累和分配的影响,从而为合理密植和科学施肥提供理论依据。[方法]在重齿毛当归的不同生长时期,采集样品,称取地上部分(叶)和地下部分(根部)的干重,通过曲线拟合进行预测分析。[结果]随移栽后天数的增加,重齿毛当归叶、根部、全株的干重均可进行曲线拟合,拟合效果良好。在不同种植密度下,重齿毛当归干物质积累变化规律基本一致;单株干物质积累量随着密度的提高而变小;单位面积产量随着密度的提高而增大;种植利润随密度的提高先增大后降低。[结论]重齿毛当归种植中,采用75933株/hm^(2)的密度,且在5—9月少量多次追肥、适当增施氮肥,有助于取得较高的产量。[Objective]The dry matter accumulation and distribution of Angelica pubescens were studied,to provide theoretical basis for rational close planting and scientific fertilization.[Method]The dry matter of aerial part(stems and leaves)and root were measured in different growth periods,then create fit curve to predict and analyze.[Result]The dry matter accumulation could be fitted curve well with the increase of the number of days after transplant.Under different planting density,the dry matter accumulation variation trends were similar.With the increase of density,the individual average accumulation got smaller and smaller,the area yield was more and more big,and the profit increased first and then decreased.[Conclusion]On the cultivation of Angelica pubescens,the density should be used 75933 plants/hm^(2).The fertilization should be divided into parts and applied in small quantities and several times,and a proper increase in nitrogen fertilizer,to help you get a higher yield.
