摘　　要：以广金钱草和何首乌为试材,采用多元统计分析方法,研究了广金钱草-何首乌间作密度以及采收期对广金钱草药材质量和产量的影响,以期建立合适的广金钱草-何首乌间作模式,推动广金钱草生态种植的发展。结果表明:在所设置的何首乌种植密度内,广金钱草茎叶比、单株干质量和产量、水溶性浸出物含量均无显著变化;随着何首乌种植密度的降低,广金钱草总黄酮、无机元素的含量呈上升趋势,夏佛塔苷含量呈下降趋势;在相同的何首乌间作密度下,随着广金钱草种植密度的降低,广金钱草的农艺性状、水溶性浸出物、总黄酮和B、Mn、Fe、Zn等9种元素含量呈先增加后减少的趋势,茎叶比、单株干质量和夏佛塔苷及Ca、Ni、Mo、Sn 4种元素的含量呈增加趋势。对广金钱草农艺性状、产量、有效成分和无机元素含量进行综合分析,在何首乌行株距60 cm×40 cm,广金钱草行株距40 cm×50 cm的间作密度下,定植后218 d采收广金钱草,其产量和质量最佳。Desmodium styracifolium and Polygonum multiflorum were used as experimental materials, the effects of the intercropping density and harvest period on the quality and yield of Desmodium styracifolium were studied by using multivariate statistical analysis methods, in order to establish a suitable intercropping model of Desmodium styracifolium and Polygonum multiflorum and promote the development of ecological planting.The results showed that the planting density of Polygonum multiflorum had no significant effect on the stem-to-leaf ratio, dry weight, yield and extract content of Desmodium styracifolium;the content of total flavonoids and inorganic elements of Desmodium styracifolium showed an upward trend, and the content of schaftoside showed a downward trend;under the same Polygonum multiflorum intercropping density, with the decrease of the planting density of Desmodium styracifolium,the agronomic traits, leachings, total flavonoid content and B,Mn, Fe, Zn and other 9 elements showed a trend of first increasing and then decreasing.The stem-to-leaf ratio, dry weight per plant and the contents of Ca, Ni, Mo and Sn were increasing.The agronomic traits, yields, active ingredients and inorganic element content of Desmodium styracifolium were comprehensively analyzed, and the yield and quality of Desmodium styracifolium were harvested at an intercropping density of 60 cm×40 cm between Polygonum multiflorum plants and 40 cm × 50 cm after colonization, while time was 218 days, the yield and quality were the best.
