在自然系统中，多样化的植物群落往往会阻止单一物种占主导地位。同样，对外来入侵植物的管理可以通过竞争物种的各种组合来实现。我们使用de Wit替代系列来比较甘薯（Ipomoea batatas（L.）Lam）、扁豆（Lablab purpureus（L.）甜）和一分钟一英里（薇甘菊Kunth）通过光合作用，植物生长，植物组织和土壤中的营养水平，竞争能力的措施。单独培养甘薯和扁豆表现出较高的总生物量，叶柄长度，叶面积比英里一分钟。在混合培养中，甘薯或扁豆或两者一起显著抑制了每分钟英里参数，即，株高、分支、叶片、不定根、生物量差异显著（P<0.05）。基于混合培养中三种植物的相对产量显著低于1.0，我们表明种内竞争小于种间竞争。计算出的指数（相对产量，相对总产量，竞争平衡指数，并在贡献的变化）表现出更高的竞争力和更高的影响力，无论是作物相比，英里一分钟。甘薯和扁豆的存在，特别是两种植物的组合，显著降低了（P<0.05）每分钟一英里的净光合速率（Pn）、抗氧化酶活性（超氧化物歧化酶、过氧化物酶、过氧化氢酶和丙二醛）、叶绿素含量和养分含量（N、P和K）。单作每分钟跑的土壤有机质、全氮和速效氮、全钾和速效钾、速效磷显著高于单作甘薯的土壤（P<0.05），但低于单作扁豆的土壤。土壤养分含量相对减少的植物混合物。甘薯和扁豆的株高、叶片、生物量、净光合速率、抗氧化酶活性以及植株和土壤养分含量在两种作物同时种植时往往比只与甘薯或扁豆混合种植时大得多。我们的研究结果表明，甘薯和风信子豆的竞争能力都大于一分钟一英里，也是一分钟一英里的抑制显着改善，通过两种作物的组合相比，无论是甘薯或风信子豆单独。
In natural systems, diverse plant communities tend to prevent a single species from dominating. Similarly, management of invasive alien plants may be achieved through various combinations of competing species. We used a de Wit replacement series to compare different combinations of sweet potato (Ipomoea batatas (L.) Lam), hyacinth bean (Lablab purpureus (L.) Sweet) and mile-a-minute (Mikania micrantha Kunth) through measures of photosynthesis, plant growth, nutrient levels in plant tissue and soil, and competitive ability. Cultured alone sweet potato and hyacinth beans exhibited higher total biomass, leafstalk length, and leaf area than mile-a-minute. In mixed culture, either sweet potato or hyacinth bean or both together significantly suppressed the mile-a-minute parameters, i.e., plant height, branch, leaf, adventitious root, and biomass (P<0.05). Based on a significantly lower than 1.0 relative yield of the three plant species in mixed culture, we showed intraspecific competition to be less than interspecific competition. Calculated indices (relative yield, relative yield total, competitive balance index, and change in contribution) demonstrated a higher competitive ability and higher influence of either crop compared to mile-a-minute. The presence of sweet potato and hyacinth bean, especially with both species in combination, significantly reduced (P<0.05) mile-a-minute’s net photosynthetic rate (Pn), antioxidant enzyme activities (superoxide dismutase, peroxidase, catalase, and malondialdehyde), chlorophyll content, and nutrient content (N, P, and K). In soil with mile-a-minute in monoculture soil organic matter, total and available N, total and available K, and available P were significantly greater (P<0.05) than in soil with sweet potato grown in monoculture, but less than in soil with hyacinth bean grown in monoculture soil. Nutrient soil content was comparatively reduced for plant mixtures. Plant height, leaf, biomass, Pn, antioxidant enzyme activities, and plant and soil nutrient contents of sweet potato and hyacinth bean tended to be much greater when grown with two crops compared to in mixture with just sweet potato or hyacinth bean. Our results suggest that the competitive abilities of both sweet potato and hyacinth bean were greater than that of mile-a-minute, and also that mile-a-minute suppression was significantly improved via a combination of the two crops compared to either sweet potato or hyacinth bean alone.
