摘　　要：为提高宿根甘蔗套种马铃薯经济效益,通过采用宽窄行种植、多种密度处理的方法,研究宿根甘蔗套种马铃薯中马铃薯密度与甘蔗产量和品质、马铃薯产量和商品率、土地复合产值和新增纯收入之间的关系。结果表明:在播幅为2.0 m的宿根甘蔗套种马铃薯宽窄行栽培中,当马铃薯密度达3.0万粒/hm2时,土地复合产值最高、经济效益最好,其中,马铃薯产量达28 600 kg/hm2,商品率达72.3%;甘蔗产量达168 000 kg/hm2,比纯种增16.2%;甘蔗糖锤度达19.9%,比纯种提高0.3个百分点;复合产值达135 985元/hm2,比甘蔗纯种增119.7%;新增纯收入122 905元/hm2,比甘蔗纯种增151.8%。In this paper we investigated the involvement of ratoon sugarcane intercropping potato through wide- narrow row planting with multiple densities primarily by exploring the relationships between potato density and yield or quality of sugarcane, between density of potato and yield or commodity rate of potato as well as between potato density and land composite value or net income, a variety of processing for improving the economic benefits of ratoon sugarcane interplanting potato. The results indicated that the land composite value was the highest and the economic benefit was the best in the range of 2.0 m while the potato density reached 30 000 particle/hm^2. Additionally, potato yield reached 28 600 kg/hm^2, commodity rate reached 72.3%; outcome of sugarcane reached 168 000 kg/hm^2 with 16.2% amplification than the Single species; cane sugar Bfix attained 19.9% with 0.30/0 higher than the Single species; composite reached 135 985 yuan/hm^2 with 119.7% higher than the Single sugarcane species; the net income 122 905 yuan/hm^2 with 151.8% more than Single cultivation of sugarcane.
