摘　　要：This study was conducted to investigate the effects of interplanting of sugarcane with watermelon and soybean on agronomic traits, yields, quality and benefit of crops, so as to provide reference for extension of the interplanting mode of sugarcane with watermelon or soybean. There were 4 treatments： CK1 （sole planting of sugarcane, no fertilization）, CK2 （sole planting of sugarcane, applying chemical fertilizers）, T1 （interplanting sugarcane with watermelon, applying chemical fertilizers ＋ cow dung）, and T2 （interplanting sugarcane with soybean, applying chemical fertilizers ＋ cow dung）. The results showed that compared with CK2, the sugarcane yield of treatment T1 reached 2.5 t/hm2, the watermelon yield was 1.02 t/hm2, and the total economic benefit increased by 3090 Yuan/hm2; the sugarcane yield in treatment T2 decreased by 7.61 t/hm2 （but not significant）, and the soybean yield was 0.35 t/hm2, and the total economic benefit increased by 720 Yuan/hm2; and the total sugar content in watermelon flesh was 8.59%, and the crude protein content in soybean was 36.15%, satisfying the quality indexes of the same agricultural products. Compared with sole planting of sugarcane, sugarcane plus watermelon or soybean interplanting mode improved economic benefit, treatment T1 showed economic benefit far higher than treatment T2, and is suitable for sugarcane regions with good water and fertilizer conditions and enough labor, and the T2 mode has simple operation, and is suitable for large-area extension.研究甘蔗套种西瓜、大豆对作物农艺性状、产量、品质及效益的影响,为蔗区推广甘蔗套种西瓜、大豆种植模式提供参考。设置4个施肥处理:CK_1(甘蔗单种,不施肥),CK_2(甘蔗单种,施化肥),T_1(甘蔗套种西瓜,施化肥+牛粪),T_2(甘蔗套种大豆,施化肥+牛粪)。结果表明,与CK_2相比,T_1处理的甘蔗增产2.5 t/hm^2,西瓜产量1.02 t/hm^2,总经济效益增加3 090元/hm^2;T_2处理的甘蔗减产7.61 t/hm^2(但没有达到显著水平),大豆产量0.35 t/hm^2,总经济效益增加720元/hm^2;西瓜肉总塘含量为8.59%,大豆粗蛋白含量为36.15%,达到了同类农产品的品质指标。甘蔗+西瓜、大豆的套种模式与甘蔗单种模式相比,提高了经济效益,T_1处理增加的经济效益远高于T_2处理,适合于水肥条件好、劳动力充足的蔗区推广,T_2模式操作简单,适合大面积推广。
