摘　　要：试验研究结果表明低丘红壤南酸枣遮荫使复合系统花生光合有效辐射减弱以及花生产量和生物量明显下降 ,与单作花生相比间作各行花生相对光合有效辐射值日变化主要与距南酸枣树行远近有关 ,与复合系统花生产量和生物量中间行高而两侧行低的趋势相一致 ,两者呈显著正相关。Agroforestry between Choerospondias axillaris trees and peanut affects the photosynthetic active radiation (PAR) of peanut in the red soil of low hilly land and the yield and biomass of peanut are obviously reduced owing to the influence of Choerospondias axillaris trees. Compared with single culture of peanut, the relative PAR variation of intercropping peanut by row mainly relates to the distance from tree line and that is in keeping with the trend of spatial variability on yield and biomass of peanut. Both yield and biomass of peanut have a significant correlation to relative PAR.
