摘要: A field experiment was conducted to compare agronomic traits during shade and light recovery periods between high yield low soybean cultivars undershade net or in "maize-soybean" relay strip intercropping 2013 2014. Twenty typical varieties with different levels cropping south of China were used. The results showed that period stem dry weight leaf significantly lower than those control, the ratio 58.4% 41.6% respectively under shade. Compared soybeans, had higher decline rate aboveground weight, length, length/ diameter, area positively correlated negatively period. During period, increased rapidly, more ratio, 47.7% 52.3% at 30 days after re- covery light. High soybeans area, smaller length/aboveground length/leaf area. In reco- very duration,
