摘　　要：采用大区比较法,在坡度27°左右的坡耕地上进行马铃薯套玉米不同种植模式的效益比较试验。结果表明:与顺坡聚垄种植相比,横坡聚垄配置地埂植物绿肥种植的马铃薯增产2 253.6 kg/hm2,玉米增产657.0 kg/hm2,马铃薯和玉米的复合产量增加2 910.6 kg/hm2,纯收入增加1 887.78元/hm2;而且,横坡聚垄配置地埂植物绿肥种植能有效减轻土壤水分和养分的流失,提高坡耕地产出率。Benefit comparison on different interplant model of potato and maize on 27 degrees sloped farmland were studied, according to large-area comparison method. The result showed that planted with transversal-slope-ridge and ridge-plant green manure, the yield of potato increased by 2 253.6 kg/hm^2, yield of maize increased by 657.0 kg/hm^2, composite yield increased by 2910.6 kg/hm^2,and net income increased by 1 887.78 yuan/hm^2, compared with that of vertical-slope-ridge plant. Meanwhile, planted with transversal-slope-ridge and ridge-plant green mature could reduced water loss and soil erosion effectively and improved the output value of sloped farmland.
