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250cm×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、270cm×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 250 cm×70 cm, 230 cm×70 cm and 270 cm×80 cm cultivation treatment should be popularized in virus-free sugarcane cultivation.
