摘　　要：目的：研究不同移栽期对川芎生长发育、干物质积累与分配和产量的影响,为川芎栽培方式的选择提供理论与实践依据。方法：以彭山种植的川芎为材料,采用单因素随机区组设计,进行田间试验,分析川芎各时期生长发育和干物质积累、分配情况。结果：移栽期影响川芎倒苗后的生长发育,且倒苗时间与移栽时间正相关;次年1月份,干物质向地下部分转移;2月份,干物质向地上部分转移;3~4月份干物质再次向地下部分转移。适宜的移栽期可使川芎在生长前期生物量积累较多,后期分配到根茎的比例较高,从而获得高产。结论：移栽期会影响川芎生长发育及生长过程中各部位干物质积累与分配,建议移栽期以8月31日左右为宜,并在川芎生长初期多施促进地上部分生长的肥料,在第二年茎叶生长期增施促进根茎生长的肥料以获得高产。Objective： To study the effect of transplanting time on growth,dry matter accumulation and distribution,and yield of Ligusticum chuanxiong,in order to provide theoretical and practical basis for the choice of cultivation methods. Methods： Ligusticum chuanxiong which planted in Pengshan were used as materials,and rearched in the field plot experiment. By the single factor randomized block design,the effects on growth development,dry matter accumulation and distribution of different periods of Ligusticum chuanxiong were analyzed. Results： Transplanting time has an important influence on the development of Ligusticum chuanxiong after lodging,and the lodging time was positively related to transplanting time; dry matter translocated to the underground part in January of the second year,and the dry matter translocated to the aerial parts in February,the dry matter secondary translocated to the underground part during March and April. Conclusion： Transplanting time affects the growth of Ligusticum chuanxiong,and affects the accumulation and distribution of every dry matter during the process of growth. Ligusticum chuanxiong transplant on August 31,and distribute more manure to improve the growth of aerial parts in the early stages,and spread additional manure to improve the growth of root stock at second year in shoot growth period,which can make a good harvest.
