A field experiment was conducted to study the effects of maize-peanut intercropping on the economic yield of the two crops and the light response of their functional leaves' photosynthesis. The results showed that maize-peanut intercropping had an obvious yield advantage, with the total economic yield being 2,896 kg hm(-2) in 2004 and 2,894 kg hm(-2) in 2005, and enhanced the land utilization rate by 14%-17%. For maize's functional leaves, the intercropping enhanced their light saturation point, compensation point, and photosynthetic rate under strong light; while for peanut's functional leaves, it reduced their light saturation point and compensation point but enhanced the apparent quantum yield of photosynthesis and photosynthetic rate under weak light, indicating that maize-peanut intercropping enhanced the utilization efficiency of strong light by maize and that of weak light by peanut, making this intercropping system present an obvious yield advantage.
进行了一项田间试验，以研究玉米-花生间作对两种作物经济产量及其功能叶片光合作用光响应的影响。结果表明，玉米-花生间作具有明显的产量优势，2004年总经济产量为2896 kg hm(-2)，2005年为2894 kg hm(-2)，土地利用率提高了14%-17%。对于玉米功能叶片，间作提高了其光饱和点、补偿点以及强光下的光合速率；而对于花生功能叶片，间作降低了其光饱和点和补偿点，但提高了弱光下的光合表观量子产率和光合速率，表明玉米-花生间作提高了玉米对强光的利用效率以及花生对弱光的利用效率，使这种间作系统呈现出明显的产量优势。
