摘　　要：以杂交水稻培两优3076为材料,在充分利用降雨的情况下,对各试验处理补充灌溉不同的水量,分别为对照(P0)灌水量的90%(P1)、80%(P2)、70%(P3)、60%(P4),研究不同灌水量下水稻的生长特性及产量,品质以及灌溉水利用效率。结果表明,与淹水灌溉相比,适当减少灌溉水量更有利于提高水稻的产量,稻米品质和灌溉水利用效率。初步研究表明,P3处理比淹水灌溉增产15.25%,节水21.34%。With hybrid rice cultivars Pei Liang You 3076 as materials,five treatments P0,P1,P2,P3,P4 were set up,and P0 was the continuous flooding irrigation.The irrigation rate of P1,P2,P3 and P4 is 90%,80%,70% and 60% of P0,respectively.Observing the growth characters,yield and quality of rice under different irrigation treatments,it was found that compared with continuous flooding irrigation,the intermittent irrigation based on irrigation rate can promote the growth and quality characters of rice and the yield is higher,the irrigation water use efficiency of rice is also improved greatly under intermittent irrigation at the same time.The result showed that P3 treatment is better,it can improve the production with 15.25%,and save water 21.34% than the continuous flooding irrigation.
