摘　　要：为探明芝麻花生等带宽间作不同行比增产效果和经济效益,于2018年进行了芝麻花生间作试验。以芝麻单作(CK1)、花生单作(CK2)为对照,设芝麻花生2∶2(M1)和芝麻花生4∶4(M2)两种等带宽间作模式,研究不同等带宽间作模式对作物干物质积累、收获指数、产量、土地当量比以及经济效益的影响。结果表明:间作降低了芝麻、花生各生育时期的干物质积累量。两种间作模式下,M2模式下芝麻、花生干物质积累量较M1模式显著增加15.0%和15.1%,在作物收获指数均无显著性差异时,M2较M1处理显著增加芝麻、花生产量16.1%和8.0%。M2处理的土地当量比为1.15,产投比为4.75,均显著高于CK1、CK2和M1处理,间作优势明显。说明芝麻花生4∶4等带宽间作模式能够通过提高作物干物质积累和分配获得较高产量,同时提高土地利用效率和经济效益。In order to research the intercropping effects of sesame and peanut with equal bandwidth on the yield increase and economic benefit,an experiment of sesame and peanut intercropping was conducted in 2018.With sesame single cropping(CK1)and peanut single cropping(CK2)as the control,two in-tercropping modes as sesame/peanut 2:2(M1)and sesame/peanut 4:4(M2)were treated to study the effects of sesame and peanut intercropping on crop dry matter accumulation,harvest index,yield,land equivalent ratio and economic benefits.The results showed that the intercropping system signifi-cantly reduced the dry matter accumulation in different growth stages of sesame and peanut.Under these two intercropping modes,the dry matter accumulation of sesame and peanut in the M2 mode in-creased significantly by 15.0%and 15.1%compared with that in the M1 mode,respectively.There was no significant difference in crop harvest index,but the yield of sesame and peanut in the M2 mode increased significantly by 16.1%and 8.0%compared with that in the M1 mode,respectively.Theland equivalent ratio of M2 treatment was 1.15,and the production-investment ratio was 4.75,which was significantly higher than that of CK1,CK2 and M1 treatment,and had obvious advantage.All these showed that the M2 mode not only obtained higher yield by increasing crop dry matter accumu-lation and distribution,but also improved the land use efficiency and economic benefits.
