| 摘 要： | 在田间试验条件下，采用覆膜栽培研究了密度对夏直播花生光合特性及产量的影响，利用LI-6400便携式光合作用测定仪，采用开放式气路测定了花生功能叶片的净光合速率、胞间CO2浓度、气孔导度等相关指标。研究结果表明，在此试验田肥力条件下，密度为15万穴/hm2时，叶面积系数、叶片净光合速率、饱果率和果重最高，荚果产量和经济系数较其它密度处理显著提高。研究认为，在此试验条件下，覆膜夏直播花生的适宜密度为15万穴/hm2。

| Abstract: | Under field condition,the effects of plant density on photosynthetic characteristics and yield of summer-planting peanut were studied by using the technology of film mulching cultivation.The net photosynthesis rate,intercellular CO 2 concentration and stomatal conductance were measured with Li-6400 Portable Photosynthesis System with an open flow gas exchange system.Among all treatments,the leaf area index,the net photosynthesis rate,as well as the number of pods per plant,seed weight,pod yield,economic coe... |
