摘要：以独活为试材,自4月4日至10月1日,采用每隔20 d对二年生独活各形态指标和根中9种矿质元素含量进行定期测定方法,研究了独活生长及根中矿质营养元素动态变化规律,以期通过平衡施肥生产优质高产药材,为独活规范化种植提供参考依据。结果表明:独活在不同生长发育阶段各形态指标变化较大,株高、叶长、叶宽、叶质量、主根长、主根粗、侧根数和根质量整体上均呈现“S”型生长变化趋势,各指标出现转折变化时间点差异较大,表现为地上部各指标早于地下部各指标变化。相关性分析结果表明,根质量与地上部各指标呈显著正相关顺序为叶质量(0.89)>叶长(0.83)>株高(0.76),与地下部各性状顺序为侧根数(0.93)>主根粗(0.92)>主根长(0.91)。根中9种矿质元素在不同发育阶段和同一时期的含量差异较大,且各元素峰值不同期。N、P、K的2次吸收高峰期在5月14日至6月23日和8月2日至8月22日,Fe、Mn、Zn、B在4月24日至5月14日和6月23日至8月2日,整体上微量元素吸收高峰期早于大量元素。建议在筛选独活优良材料时,可将叶质量,叶长和株高作为间接选择的首选指标;在矿质元素吸收高峰期间,择机合理施用大量元素和微量元素,更有利于独活的生长和产量提高。
Taking Angelica pubescens Radix as the test material,from April 4th to October 1st,a regular measurement method was adopted every 20 days to study the growth and dynamic changes of mineral nutrients in the roots of biennial Angelica pubescens Radix,in order to produce high-quality and high-yield medicinal materials through balanced fertilization,and provide reference for standardized planting of Angelica pubescens Radix.The results showed that the morphological indexes of Angelica pubescens Radix changed greatly at different growth stages,the plant height,leaf length,leaf width,leaf weight,main root length,main root diameter,number of lateral roots and root weight all showed an‘S’growth trend.There was a significant difference in the time point of turning change of each index,and the change of each index of the aboveground part was earlier than that of the underground part.The correlation analysis showed that the leaf weight(0.89)>leaf length(0.83)>plant height(0.76)was the most significant positive correlation order between root weight and aboveground indexes,and the number of lateral roots(0.93)>main root diameter(0.92)>main root length(0.91)was the most significant positive correlation order between root weight and underground indexes.The contents of 9 mineral elements in roots varied greatly at different growth stages and at the same time,and the peak value of each element appeared in different period.The two absorption peaks of N,P and K were from May 14th to June 23rd and from August 2nd to August 22nd,Fe,Mn,Zn and B from April 24th to May 14th and from June 23rd to August 2nd,and the microelement absorption peaks earlier than for major elements.It was suggested that leaf weight,leaf length and plant height should be selected as the first indexes of indirect selection.The major elements and microelement should be used reasonably during the peak period of mineral absorption,it was more advantageous to the growth and high-yield of Angelica pubescens Radix.
