摘要: 为明确影响八爪金龙药材产量和品质的关键土壤因子,以贵州24个居群的朱砂根和红凉伞为研究对象,测定其单株产量、水分、总灰分、酸不溶灰分、水溶性浸出物、岩白菜素含量,以及土壤pH值和全氮、铵态氮、全磷、有效磷、全钾、速效钾、有机质含量,应用偏最小二乘法计算上述土壤因子对药材产量和品质影响的变量投影重要性(VIP)值,明确影响八爪金龙产量和品质的关键土壤因子,并基于产量高、品质优的目标利用线性规划方法提出土壤因子的优化方案。结果显示,不同产地的八爪金龙药材产量与品质存在显著(p<0.05)差异,部分药材样品的质量未能达到《中国药典》(2020年版)对朱砂根的要求。土壤有效磷、速效钾、铵态氮含量和pH值显著影响八爪金龙药材的产量与质量。优质高产目标下八爪金龙药材生产的适宜土壤理化性状为:土壤pH值在4.82~6.92,全氮含量为9.56 g·kg-1,铵态氮含量在2.26~8.24 mg·kg-1,全磷含量为627 mg·kg-1,有效磷含量在24.42~33.60 mg·kg-1,全钾含量在1.45%~2.64%,速效钾含量在139~1 128 mg·kg-1,有机质含量为57.83 mg·kg-1。在此条件下,单株产量为45 g,水分含量为11.77%,总灰分含量为3.78%,酸不溶灰分含量为0.81%,水溶性浸出物含量为37.46%,岩白菜素含量为1.54%。

Abstract:

To elucidate the primary soil factors influencing the yield and quality of Radix Ardisia, 24 populations of Ardisia crenata and A. crenata var. bicolor(medicinal materials of Radix Ardisia) in Guizhou Province of China were selceted as the research subjects. Their medicinal yield, moisture content, total ash content, acid-insoluble ash content, water-soluble extractives content, and bengenin content were determined, as well as soil parameters, such as pH value, total nitrogen content, ammonium nitrogen content, total phosphorus content, available phosphorus content, total potassium content, available potassium content, and organic matter content. The partial least squares method was employed to calculate the variable importance in projection (VIP) values, thereby identifying the key soil factors impacting the yield and quality of the collected samples. To realize high yield and superior quality, an optimization strategy for soil factors was developed by using the linear programming method. It is shown that there was significant (p<0.05) difference in the yield and quality of the collected samples. The quality of some samples fails to meet the requirements stipulated in the Pharmacopoeia of the People’s Republic of China(2020 Edition). The contents of soil available phosphorus, available potassium, ammonium nitrogen, and soil pH value significantly influence the yield and quality of the medicinal materials of Radix Ardisia. To achieve high quality and yield, the ideal soil physical and chemical properties are as follows: pH value of 4.82 to 6.92, total nitrogen content of 9.56 g·kg-1, ammonium nitrogen content of 2.26-8.24 mg·kg-1, total phosphorus content of 627 mg·kg-1, available phosphorus content of 24.42-33.60 mg·kg-1, total potassium content of 1.45%-2.64%, available potassium content of 139-1 128 mg·kg-1, and organic matter content of 57.83 mg·kg-1. Under these conditions, the yield per plant is 45 g, with a moisture content of 11.77%, total ash content of 3.78%, acid-insoluble ash content of 0.81%, water-soluble extractives content of 37.46%, and bengenin content of 1.54%.
