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.
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.
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.
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.
研究移栽时间对川芎生长、干物质积累与分配及产量的影响，为栽培方式的选择提供理论与实践依据。
以彭山种植的川芎为材料，进行田间小区试验。采用单因素随机区组设计，分析不同时期移栽对川芎生长发育、干物质积累与分配的影响。
移栽时间对川芎倒伏后的发育有重要影响，倒伏时间与移栽时间呈正相关；干物质在第二年1月向地下部分转移，2月向地上部分转移，3月和4月干物质再次向地下部分转移。
移栽时间影响川芎的生长，影响其生长过程中各干物质的积累与分配。川芎于8月31日移栽，前期多施肥料以促进地上部分生长，在地上部分生长时期的次年，再追施肥料以促进根茎生长，如此可获丰收。
