摘　　要：为探究最优的木薯与红籽瓜间套种模式及其经济效益,试验设5个处理,即3个不同间套种处理及2个纯种处理,并综合分析了土壤理化性状、主要农艺性状、产量品质及经济效益.结果表明,间套种模式的土壤养分含量和土壤酶活性要优于单作;以T2处理(2行红籽瓜之间种植3行木薯)综合表现最优,木薯单株薯质量达(5.21±0.05)kg,块根淀粉含量达(31.98±0.45)%,红籽瓜种仁蛋白质含量达(37.42±0.31)g·kg^-1;经济效益总利润达57 711.8元·hm^-2.在间套种模式下,以T2处理间套种模式最合理,经济效益最高.In order to explore the optimal intercropping model and economic benefits between cassava and red seed melon, five different treatments were carried out, including three different intercropping treatments and 2 control groups, the soil physicochemical characters, main agronomic traits, yield quality and economic benefits were analyzed. The results showed that the soil nutrient content and enzyme activity of the intercropping model were better than those of the monoculture. The T2 treatment of "2 rows red seed melon planted with 3 rows cassava" exhibited the best comprehensive characters. The single plant weight of cassava was up to 5.21 kg, the starch content of roots was 31.98%, and the protein content of seeds in red seed watermelon fruit reached to 37.42 g·kg^-1 Furthermore, the economic benefit reached to 46 292.8 yuan·hm^-2. In the intercropping mode, T2 test was the best mode and showed the highest economic benefit.
