图2 不同行距配置处理下大豆冠层透光率和红光与远红光比值变化 A1~A4为玉米大豆行距配置处理, 分别为A1 180 cm + 20 cm; 宽行180 cm, 窄行20 cm、A2 160 cm + 40 cm、A3 140 cm + 60 cm和A4 120 cm + 80 cm。MS为单作大豆处理。
Fig. 2 Changes of the PAR transmittance and redfar-red ratio in soybean canopy under different row spacing patterns Maize-soybean intercropping planting patterns: A1 “180 + 20” wide-narrow row planting, i.e. wide row of 180 cm and narrow row of 20 cm; A2 “160 + 40” wide-narrow row planting; A3 “140 + 60” wide-narrow row planting; A4 “120 + 80” wide-narrow row planting. MS stands for monoculture soybean.
