摘要： 以花生新品种丰花1号高产栽培大田为材料，结荚初期人工摘除50%叶片、摘除50%果针，以不进行处理的作对照。结果表明：在处理后前期，摘叶处理虽然单叶光合速率上升，LAI增长速率增大，对叶片减少有补偿效应，但是叶绿素降解加快，含量下降，衰老加快而形成早衰现象，物质积累少，单果重、生物产量、经济产量、经济系数低于对照。摘除果针处理单叶光合速率虽有降低，但叶绿素含量高，降解速度慢，明显延缓植株衰老，LAI一直处于高水平，物质积累量大，荚果充实好，生物产量、经济产量、经济系数显著高于对照和摘叶处理。

Abstract: Fenghua 1,the new variety of peanut for high yield field,was used in this study.50% peg or 50%leaf in plant are removed artificially in polding phase,natural plant is control.Although leaf decreaseun hecompensated a little by the inreusing photosynthesis rate of single leaf and LAI high increasing rate,hlorophylldecomposes quickly and its content decreases,which accelerate the senescence of plant.
