Taking the Arachis hypogaea cv. 'Qinghua 7' as test material, a field experiment was conducted to study the effects of different cultivation modes on the leaf photosynthetic characteristics and yield of summer-sowing peanut after wheat harvest. As compared with conventional cultivation mode, high-yield protective cultivation mode promoted the leaf growth, significantly improved the leaf area index (LAI), and maintained a longer time of high LAI and chlorophyll content. Meanwhile, the net photosynthetic rate, stomatal conductance, and transpiration rate of functional leaves under high-yield protective cultivation mode were higher while the intercellular CO2 concentration was lower, which induced the photosynthetic efficiency of functional leaves being significantly improved. Therefore, under high-yield protective cultivation mode, the yield per peanut plant was higher, the pod yield increased significantly, and the economic coefficient improved obviously. Both film mulching and straw returning could also improve the leaf photosynthesis of summer-sowing peanut, and increase the peanut yield. It was suggested that high-yield protective cultivation mode could effectively alleviate the adverse factors of summer-sowing peanut, such as the short growth period and lower productivity per plant, being a practical high-yield cultivation mode of summer-sowing peanut.
以花生品种‘青花7号’为试验材料，进行田间试验，研究不同栽培模式对麦后夏播花生叶片光合特性及产量的影响。与传统栽培模式相比，高产保护性栽培模式促进了叶片生长，显著提高了叶面积指数（LAI），并维持较高LAI和叶绿素含量的时间更长。同时，高产保护性栽培模式下功能叶的净光合速率、气孔导度和蒸腾速率较高，而胞间CO₂浓度较低，这使得功能叶的光合效率显著提高。因此，在高产保护性栽培模式下，单株花生产量较高，荚果产量显著增加，经济系数明显提高。地膜覆盖和秸秆还田也能提高麦后夏播花生的叶片光合能力，增加花生产量。表明高产保护性栽培模式能有效缓解麦后夏播花生生长周期短、单株生产力低等不利因素，是一种实用的麦后夏播花生高产栽培模式。
