摘　　要：为了探讨宽厢宽带套作增效模式在脱毒果蔗上的应用效果,以脱毒果蔗广东蜡蔗和黔糖3号为材料,进行了5种宽厢宽带套作一季辣椒的栽培试验。结果表明：5种宽厢宽带套作栽培均能提高脱毒果蔗的产量及产值,以250 cm×70 cm处理效果最好,广东蜡蔗和黔糖3号的产量分别比CK增加5%~25.1%、7.6%~17.2%,且230 cm×70 cm、270 cm×80 cm处理的增产增收效果较好。这3种宽厢宽带套作模式可在生产上推广试用。A hot pepper variety was intercropped with Guangdong wax sugarcane and Qiantang 3 under five different wide ridge and spaced sowing patterns to study the effects of wide ridge and spaced sowing pattern on yield and economic benefit of virus-free sugarcane variety.The results showed that five different wide ridge and spaced sowing patterns all could improve yield and economic benefit of virus-free sugarcane varieties,the yield and economic benefit of virus-free sugarcane under 250cm×70cm treatment was maximum among five wide ridge and spaced sowing patterns,the yield of Guangdong wax sugarcane and Qiantang 3 was 5%～25.1% and 7.6%～17.2% higher than CK respectively.Three wide ridge and spaced sowing intercropping patterns with 250cm×70cm,230cm×70cm and 270 cm×80 cm cultivation treatment should be popularized in virus-free sugarcane cultivation.
