摘　　要：采用玉米品种辽单1205与耐荫花生品系S60、P12分别进行2‖10和2‖20两种形式的间作,以探讨适合风沙区花生的高产高效和防风蚀栽培形式。结果表明,间作条件下靠近玉米的花生叶片净光合速率、蒸腾速率、根茎叶干质量、产量等均不同程度下降,且越靠近玉米,下降幅度越大,品系S60玉米每侧2行受到影响,P12每侧3行受到影响。两种间作形式土地当量比均大于1,2‖20形式的经济效益大于2‖10形式,与花生单作无显著差异。玉米辽单1205与耐荫花生S60以2‖20形式间作适合风沙区花生种植。Corn Liaodan 1205 and shade-tolerant peanut strains S60 and P12 were intercropped in two forms of 2‖10 and 2‖20,respectively,in order to explore the cultivation of peanut with high yield,high efficiency and wind erosion prevention suitable for wind-sand area.The results showed that the net photosynthetic rate,transpiration rate,root stem and leaf dry weight and yield of peanut leaves close to corn all decreased to varying degrees,and the closer to the corn,the greater the decline.The two rows on each side of strain S60 corn were affected,and the three rows on each side of P12 were affected.The land equivalent ratio of the two intercropping forms is more than 1,and the economic benefit of 2‖20 forms is greater than 2‖10 forms,which is not significantly different from peanut alone.
