摘　　要：2016—2019年对水稻开展不同灌溉方式的比较试验,研究不同灌溉方式下的节水减排效果和水稻产量。结果表明:结合不同灌溉方式下灌水量、排水量、灌水次数、水分利用率以及水稻产量等指标,可知间歇灌溉应用效果更好。间歇灌溉方式下早稻和晚稻的灌水量分别为(201.5±34.8)和(240.9±42.1)mm,水分生产率分别为1.35和1.38 kg/m^(3),产量分别为(6189.0±373.5)和(6409.0±682.5)kg/hm^(2)。间歇灌溉结合70%化学肥料+30%菌肥的配比下,水稻产量更高。该研究结果可为水稻高效生产提供理论依据。From 2016 to 2019,the comparison experiment on rice under different irrigation methods was conducted,so as to investigate the effects of water saving,emission reduction and rice yield under different irrigation methods.The results showed that the application effect of intermittent irrigation was better in combination with indicators such as irrigation volume,drainage volume,irrigation frequency,water use efficiency,and rice yield under different irrigation methods.The irrigation volume of intermittent irrigation technology for early rice and late rice were(201.5±34.8)and(240.9±42.1)mm respectively,the water productivity was 1.35 and 1.38 kg/m^(3) respectively,the rice yield was(6189.0±373.5)and(6409.0±682.5)kg/hm^(2) respectively.Under the ratio of intermittent irrigation combined with 70%chemical fertilizer and 30%bacterial fertilizer,rice yield was higher.The study results could provide the theoretical basis for efficient rice production.
