摘　　要：以辽星1号和辽优5218为试材,研究孕穗期低温胁迫下叶面喷施"易丰收"液体复合肥对低温伤害的预防和改善效果。结果表明,叶面喷施"易丰收"液体复合肥可明显改善低温对水稻株高、穗抽出度、单株草重、单株实粒数、单株结实率等性状的伤害,低温处理前7 d喷施效果要优于低温处理后喷施。"易丰收"液体复合肥在杂交稻上的应用效果要好于常规稻。Taking Liaoxing1 and Liaoyou5218 at booting stage as test materials,this paper studied the preventive effects of liquid compound fertilizer ＇YiFengshou＇ on injury of low temperature stresses on rice.The results showed that injury of low temperature stress on rice plant height,panicle exertion,straw weight,number of full-filled grains and spikelet fertility were effectively improved.It was more better to foliage spray one week before low temperature treatment than that after the low temperature treatment.The preventive effects on hybrid rice was better than that of conventional rice.
