| 中文摘要: |
| 评估喀斯特高海拔山区百香果间作大豆模式的生态和经济效益，为日后在相同地貌区域推广百香果间作大豆模式提供理论依据。2019年-2021年在广西西北部喀斯特高海拔山区（938m）开展间作效果评估工作，探讨单作百香果模式和百香果间作大豆模式对杂草生长、土壤营养成分、作物产量及经济效益的影响。结果表明，百香果间作大豆能显著抑制杂草地上部分的生物量（p＜0.05）。2019年-2021年间，单作百香果模式杂草的平均高度比百香果间作大豆模式高出3.94倍、3.31倍和3.88倍，杂草的总重量分别高6.07倍、6.97倍和5.94倍。进一步分析发现，百香果间作大豆模式对土壤营养成分影响较小，但是能提高土地产出率。2019年-2021年两种模式的土地当量比（LER）分别为1.92、1.94和1.91，增产率为92.35%、94.07%和90.67%。2019年-2021年百香果间作大豆模式的产值比单作百香果模式增加了16020元/公顷、16218元/公顷和15714元/公顷。 |

| Evaluate the ecological and economic benefits of passion fruit & soybean intercropping in Karst landform of high elevation mountainous region, and provide theoretical basis for the popularization and application of passion fruit & soybean intercropping in the same landform area in the future. A field investigation was carried out in northwestern Guangxi province from 2019 to 2021, where is karst high-altitude mountainous area (938m)，to explored the effects of single cropping passion fruit and passion fruit & soybean intercropping on weed growth, soil nutrients, crops yield and economic benefit. The above-ground biomass of weeds was significantly inhibited in passion fruit & soybean intercropping (p < 0.05). From 2019 to 2021, the average weed height was increased by 3.94 times, 3.31 times and 3.88 times, and the total weed weight increased by 6.07 times, 6.97 times and 5.94 times, in single cropping passion fruit compared with the passion fruit & soybean intercropping. Further analysis found that the passion fruit & soybean intercropping had little effect on soil nutrients, but could increase the land yield. The land equivalent ratio (LER) from 2019 to 2021 was 1.92, 1.94 and 1.91, and the yield increase rate were 92.35%, 94.07% and 90.67%, respectively. The income of passion fruit & soybean intercropping was increased by 16020 yuan/ha in 2019, 16218 yuan/ha in 2020 and 15714 yuan/ha in 2021 compared with that of single cropping passion fruit.The passion fruit & soybean intercropping has higher ecological and economic benefits in Karst landform of high elevation mountainous region |
