以湘早籼45号为材料，采用田间小区试验，研究养分运筹对早稻叶片叶绿素及类胡萝卜素含量的影响。结果表明：高产高效施肥与农民习惯施肥相比，在节氮20%的条件下，通过增施有机肥及调节后期施氮比例，益阳、湘阴早稻叶片灌浆期总叶绿素含量分别提高29.27%、38.20%，类胡萝卜素含量分别提高13.16%、30.12%，增产4.20%、4.80%。益阳超高产高效施肥 A和 B处理早稻叶片灌浆期总叶绿素含量比农民习惯施肥分别提高53.91%、53.73%，类胡萝卜素含量分别提高35.95%、37.47%，增产16.60%、18.75%；湘阴超高产高效施肥 A和 B处理早稻叶片灌浆期总叶绿素含量比农民习惯施肥分别提高57.82%、56.80%，类胡萝卜...

The objective of this study was to investigate the effects of different nutri-ent application models on the contents of chlorophyl and carotenoid in the functional leaves of early rice. Using rice cultivar Xiangzaoxian45 as experimental materials, the experiment was performed by designing 6 treatments, i.e., T1 （fertilization without nitrogen）, T2（local conventional fertilization）, T3（fertilization for high yield and high effi-ciency）, T4 （fertilization for super high yield）, T5 （fertilization application for super high yield and high ...
