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%，类胡萝卜素含量分别提高54.88%、57.03%，增产10.10%、6.75%。相关分析表明：不同地力环境条件下，早稻叶片叶绿素及类胡萝卜素含量与产量呈显著或极显著正相关（P＜0.05或 P＜0.01）。养分运筹模式对早稻叶片叶绿素及类胡萝卜素含量的促进作用显著。

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 efficiency A) and T6 (fertilization application for super high yield and high efficiency B) in two experimental plots Yiyang and Xiangyin. The results showed that T3 respectively increased the contents of chlorophyl and carotenoid at fil ing stage by 29.27%, 38.20% and 13.16%, 30.12% in Yiyang and Xiangyin, as wel as yield of early rice by 4.20%, 4.80% to T2 on the condition of saving 20% ni-trogen fertilizer. Additional y, T5 and T6 on the condition of saving 16.7% nitrogen fertilizer by T4 increased the contents of chlorophyl and carotenoid of fil ing stage by 53.91%, 53.73% and 35.95%, 37.47% in Yiyang and Xiangyin, as wel as yield of early rice by 16.60%, 18.75% to T2 in Yiyang; increased the contents of chlorophyl and carotenoid at fil ing stage by 57.82%, 56.80% and 54.88%, 57.03% in Yiyang and Xiangyin, as wel as yield of early rice 10.10%, 6.75% to T2 in Xiangyin. More-over, there was a significant correlation or an extremely significant correlation be-tween yield and the contents of chlorophyl and carotenoid at different soil fertility level (P<0.05 or P<0.01). Therefore, nutrient application plays an important role in the contents of chlorophyl and carotenoid in the functional leaves of early rice.
