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 effects of different transplanting periods on the growth and development, dry matter accumulation, distribution and yield of Ligusticum chuanxiong Hort, and to provide theoretical and practical basis for the selection of cultivation methods of Ligusticum chuanxiong. Methods: Chuanxiong rhizome grown in Pengshan was used as the material. Single factor randomized block design was used to carry out field trials to analyze the growth, development, accumulation and distribution of dry matter of Chuanxiong Rhizoma. Results: The effects of transplanting period on the growth and development of Chuanxiong rhizome after downtilt seedlings were studied, and the time of inverted fellowship was positively correlated with the transplanting time. In January of the following year, the dry matter translocated to the underground part. In February, the dry matter translocated to the aboveground part. The dry matter is again transferred to the subsurface in the month. Appropriate transplanting period can make Chuanxiong more biomass accumulation in the early growth stage, late distribution to the higher proportion of rhizomes to obtain high yield. Conclusion: The transplanting period will affect the growth and development of Chuanxiong Rhizoma Chuanxiong dry matter accumulation and distribution of various parts of the proposed transplanting period around August 31 is appropriate, and in the early growth of Chuanxiong more to promote the growth of fertilizer on the ground, in the The second year stem and leaf growth stage by promoting the growth of rhizome fertilizer to obtain high yield.
