摘要:

为探明淫羊藿(Epimedium brevicornu Maxim.)营养元素吸收分配特征和药效成分积累规律,明确影响药效成分积累的特征元素,以3年生淫羊藿为研究对象,测定干物质积累量、营养元素含量及叶中黄酮类成分含量,并分析叶中黄酮类成分与营养元素之间相关性。结果表明:(1)随着生育期延长,干物质积累呈先升后降趋势,果后生长期(T5)干物质快速积累,达到最大值。(2)生育期内地上部氮和磷含量总体呈下降趋势,而地下部与之相反,地上部钾含量呈下降-上升-下降的变化规律,地下部钾含量无明显变化,结果期(T4)氮、磷、钾元素净积累量最大。(3)生育期内11种营养元素积累量表现为氮>钙>钾>镁>磷>硫>铁>锰>锌>铜>硼。(4)叶中黄酮类成分积累量呈先升后降趋势。(5)相关性分析表明,黄酮类成分含量与镁、铁、铜含量协同作用显著,与硼、锰含量存在拮抗作用;逐步回归分析表明,氮、钙、锰、铁元素是影响叶中黄酮类成分含量的特征元素。可见,淫羊藿干物质积累与养分积累在结果期最为关键,应在结果期到达前施入大量元素,以氮肥和钾肥为主,保证镁、铁、铜元素供给。药效成分积累量在果后生长期最大,结合该试验结果与当地气候条件,建议甘肃临夏及相似地区淫羊藿叶片于9月上旬采收。

Abstract:

In order to explore the absorption and distribution characteristics of nutrient elements and the accumulation of pharmacodynamic components in E. brevicornu, and to clarify the characteristic elements affecting the accumulation of pharmacodynamic components, the dry matter accumulation, nutrient element content and flavonoid content in leaves of 3-year-old E. brevicornu were determined, and the correlation between flavonoid components and nutrient elements in leaves was analyzed. The results showed that (1)with the plant growth, the dry matter accumulation increased first and then decreased, and the dry matter accumulation was rapid and reached the maximum in the post-fruit growth period(T5). (2)The contents of nitrogen(N) and phosphorus(P) in the upper part showed a decreasing trend at the growth stage, while the contents of potassium(K) in the underground part showed a decreasing-rising-decreasing trend, while the contents of K in the underground part had no obvious change, and the net accumulation of N, P and K was the largest in the fruiting period(T4). (3)The accumulation of 11 nutrient elements during the growth period was listed in a decreasing order: N>Ca>K>Mg>P>S>Fe>Mn>Zn>Cu>B. (4)The accumulation of flavonoids in leaves increased first and then decreased. (5)The correlation analysis showed that the flavonoid content had synergistic effect with the contents of magnesium(Mg), iron(Fe) and copper(Cu), and had antagonistic effect with the contents of boron (B) and manganese(Mn). Stepwise regression analysis showed that N, calcium(Ca), Mn and Fe were the characteristic elements that affected the content of flavonoids in leaves. In conclusion, dry matter accumulation and nutrient accumulation of E. brevicornu were the most critical in the fruiting period. The macroelements should be applied before the fruiting period, mainly N and K fertilizers, ensuring the supply of Mg, Fe and Cu. The accumulation of pharmacodynamic components was the largest in the post-fruit growth period. Combined with the results of this experiment and local climatic conditions, it was recommended that the leaves of E. brevicornu in Linxia of Gansu Province and similar areas should be harvested in early September.

Key words: Epimedium brevicornu Maxim., dry matter accumulation, nutrient absorption characteristics, pharmaco-dynamic components, accumulation and distribution
