农林复合系统作为最有前途的替代种植方式，被广泛认为是缓解快速增长的人口与有限的耕地资源之间矛盾的重要战略。以龙胆苦苷含量为指标，筛选龙胆的最佳种植模式，为龙胆的可持续供应和应用提供科学依据。通常，傅里叶变换红外光谱(FTIR)能有效地全面监测和反映天然物质的全部成分。采用FTIR和化学计量学相结合的方法进行鉴别。本研究从不同的复合种植模式中进行了比较。偏最小二乘判别分析结果表明，黄瓜的种植年限。连翘对龙胆苦苷含量的影响比山茶大。1.5~2年生的龙胆苦苷含量。硬度较高。小波去噪对分类效果较好。龙胆苦苷含量较高的样品相对聚在一起，龙胆苦苷含量较低的样品被归为另一大类。我们的调查显示，G。结果表明，C.符合《中国药典》规定的龙胆苦苷含量要求。那个两岁的小孩。与12岁的C一起生长。根据本研究，甜菜是最佳的复合种植模式。本研究提出了黄瓜的最佳复合种植模式。有利于提高土地利用效率和经济效益。
Agroforestry system, as the most promising substitute plantation approach, has been widely regarded as a prominent strategy for mitigating the conflicts between rapid growing population and limited arable land resources. This paper aims to screen the optimal planting pattern forGentiana rigescensbase on the content of gentiopicroside, providing the scientific basis for sustainable supply and application of this plant. Generally, Fourier transform infrared (FTIR) spectroscopy is effective to integrally monitor and reflect the whole constituents of natural materials. FTIR combined with chemometrics was used for distinguishing theG. rigescensfrom different compound planting models in this research. The result of partial least square discriminant analysis implied that planting year ofG. rigescenshad a greater impact on the content of gentiopicroside than that ofCamellia sinensis. The gentiopicroside content in 1.5- or 2-year-oldG. rigescenswas higher. Wavelet denoising was effective for the classification. Samples which had higher contents of gentiopicroside were clustered together relatively, while those with lower contents of gentiopicroside were classified into the other large category. Our investigation revealed thatG. rigescenscan be successfully cultivated withC. sinensis, which met the requirement of the gentiopicroside content recommended by Pharmacopoeia of the People’s Republic of China. That 2-year-oldG. rigescensgrown with 12-year-oldC. sinensiswas the optimal compound planting pattern, according this study. The present study provided the optimal compound planting pattern ofG. rigescens, which is helpful for improving land-use efficiency and economic returns.
