[Effect of Transplanting Time on Growth,Dry Matter Accumulation and Distribution,and Yield of Ligusticum chuanxiong].

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.
