摘    要:目的:研究川白芷生长指标、养分及有效成分的动态变化及相互关系,为合理施肥提供理论依据。方法:定期采样并测定相关形态指标、氮、磷、钾及根部有效成分含量与积累量等。结果:秋播川白芷营养生长过程可初步划分为:苗期、地上部分旺盛生长期和根旺盛生长期。随着生长发育,川白芷株高及地上部分干重先增大后减小,根长、根粗、干重逐渐增加;不同时期川白芷对氮、磷、钾的吸收量不同,总体而言,植株对氮、钾吸收量较高,磷较低,其累积量表现为氮钾磷,地上部分氮磷钾积累量逐渐减少,根部氮磷钾积累量逐渐增加,养分从地上部分逐渐向根部转运;根部欧前胡素与异欧前胡素含量呈下降-上升-下降-上升的变化趋势,其积累量逐渐增加。此外,地上部分磷、钾积累量与欧前胡素含量呈显著正相关;而异欧前胡素含量则与根部氮磷钾的积累量呈显著正相关。结论:从4月下旬起,川白芷进入根部旺盛时期,根部成为生长中心,其干物质、氮、磷、钾及欧前胡素与异欧前胡素积累量迅速增加,此时应注意氮、磷、钾肥的平衡施用。

Abstract:Objective : To study the absorption and transformation of N, P, K and plant growth as well as the accumulation of active ingredients in Angelica dahurica var. formosana from Sichuan province and provide basis for rational fertilization. Method : Samples were collected in different growth phrases, and correlative morphological indexes, the contents and accumulations of N, P, K and active ingredients were determined. Result : The vegetative growth period of A. dahurica var. formosana sowed in autumn could be preliminarily divided into three phases: seedling period, aerial-part peak growth period and root peak growth period. With the development, the plant height and aerial part dry weight increased at the earlier stage, and then decreased. But the root length, root diameter, and root dry weight increased. The absorptive capacity of N, P and K varied among different developing stages. In general, the absorptive capacity of N and K was the higher than that of P. The order of total nutrition accumulation was N > P > K, the accumulation of N, P and K in aerial part decreased gradually during the growth period, while the accumulation of N, P and K in root increased gradually. The concentration of imperatorin and isoimperatorin showed decreasing-increasing-decreasing-increasing trend, while the accumulation of them increased gradually. And the correlation analysis results showed that the accumulation of P and K in aerial part had positive correlation with the concentration of imperatorin in root, the accumulation of N, P and K in root had positive correlation with the concentration of isoimperatorin in root. Conclusion : From late April, A. dahurica var. formosana from Sichuan province entered root peak growth period and the accumulation of N, P, K, imperatorin and isoimperatorin in root increased rapidly. So the balanced application of fertilizer should be considered.
