摘　　要：以晋南春播3个黑花生品种(系)为研究对象,结合下针后期人工减源疏库栽培措施,研究其叶片的光合特性及产量的变化规律。结果表明,随着摘叶去针10%～50%处理比例的增加,叶片净光合效率、蒸腾速率持续显著提高,气孔导度和水分利用效率均要好于对照;在10%处理比例时单株生产力和田间产量最高,单株果数随去针数的增加而减少,结果率和饱果率在50%比例时较高;除结果率指标在品种间变化不显著外,其余产量性状指标在品种、处理间均达到显著差异水平;在品种(系)间晋花9号对摘叶去针处理更敏感,中花9号补偿适应能力更强,临黑3号增产效果最好。To explore leaves photosynthetic traits and yield's changing rules under different source-sink treatment in acicula forming later stage,three breeds were surveyed in southern Shanxi spring sowing peanut belt.The results showed that leaf net photosynthesis efficiency and transpiration rate improved significantly with leaf picking and acicula reducing treatment percent increasing.The stomatal conductance and water use efficiency of leaves were better than control groups.Single plant productivity and yield traits showed the highest level in 10 percent treatment.Fruit number per plant reduced with cutting acicula increase.Fruit ratio and full-pod rate was higher in 50 percent.The yield correlated traits had significant difference in breeds and treatments except fruit ratio in breeds.Jinhua 9 was more sensitive to leaf picking and acicula reducing treatment.Zhonghua 9 had more compensation and adaptation ability.Linhei 3 showed higher yield increasing effect.
