摘　　要：以4个水稻品种为材料,研究不同节水灌溉模式对水稻生物学特性和产量的影响。结果表明：节水灌溉模式有利于水稻早熟,降低水稻叶面积。适当节水处理（控灌Ⅰ）可提高产量3.1%~5.2%。Using 4 rice varieties,the effect of different water-saving irrigation treatments on rice biological characteristics and yield were studied.The results showed that effects of water-saving treatments on rice growth were in favor of promoting early-maturing and reducing leaf area.The appropriate water-saving irrigation treatment could increase yield by 3.1%~5.2%.
