摘要
猕猴桃叶片光合速率日变化呈双峰曲线，不同龄叶片具有不同的光合速率。套种植物狗尾草、美洲黑杨和印尼大豆的光合速率日变化也基本呈一双峰曲线。套种可以明显降低中午猕猴桃光合“午睡”，增加光合速率与各环境因素的相关性，从空间上和时间上更充分地利用光能，从而改善猕猴桃冠幕微气候，提高光能利用率。
Diurnal variation of photosynthetic rate and its major factors were determined in comprehensively managed Actinidia deliciosa stand. Photosynthetic rate of A. deliciosa and its interplanting plants (Glycine willd, Populus deltoides, Setaria viridis) reaches peaks at 10:00 and 14:00 respectively in dry-heat conditions and were affected by environmental factors. The net photosynthetic rate of different leaves was different. Interplanting can reduce the sleeping at noon, increase the relation between photosynthetic rate and environmental factors, and improve canopy microclimate and efficiency for solar energy utilization of A. deliciosa.
