摘　　要：评估喀斯特高海拔山区百香果间作大豆模式的生态效益和经济效益,可为相同地貌区域推广百香果种植提供参考。2019—2021年在广西西北部喀斯特高海拔山区(938 m)设置百香果单作和间作大豆种植处理,测定比较不同种植模式对百香果园杂草生长、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、2020、2021年,百香果单作处理的杂草平均高度是百香果间作大豆的3.94倍、3.31倍和3.88倍,杂草总质量分别是6.07倍、6.97倍和5.94倍。百香果间作大豆对土壤营养成分影响较小,但是能提高土地产出率。2019、2020、2021年百香果单作和间作的土地当量比(LER)分别为1.92、1.94和1.91,间作增产率分别为92.35%、94.07%和90.67%,百香果间作大豆的产值比百香果单作分别增加16020、16218和15714元/hm^(2)。Evaluating the ecological and economic benefits of passion fruit&soybean intercropping in Karst landform of high elevation mountainous region can provide theoretical basis for the popularization and application of passion fruit&soybean intercropping in the same landform area in the future.A trial with the treatments of passion fruit monoculture and passion fruit&soybean intercropping were carried out in Karst high-altitude(938 m)mountainous area of northwestern Guangxi Province from^(2)019 to 2021 to explore the effects of different cropping modes on weeds growth,soil nutrients,crop yield and economic benefit.The results showed that the aboveground biomass of weeds was significantly inhibited in passion fruit&soybean intercropping(p<0.05).In 2019,2020 and 2021,compared with the passion fruit&soybean intercropping,the average weeds height of passion fruit monoculture was increased by 3.94 times,3.31 times and 3.88 times,and the total weeds weight was increased by 6.07 times,6.97 times and 5.94 times,respectively.The passion fruit&soybean intercropping had little effect on soil nutrients,but could increase the land output rate.The land equivalent ratio(LER)of passion fruit monoculture to passion fruit&soybean intercropping in 2019,2020 and 2021 was 1.92,1.94,1.91,respectively,and the yield increase rate of intercropping was 92.35%,94.07%,90.67%,respectively.The output value of passion fruit&soybean intercropping was increased by 16,020 yuan/hm^(2),16,218 yuan/hm^(2)and 15,714 yuan/hm^(2)in 2019,2020 and 2021,respectively compared with that of passion fruit monoculture.
