摘 要：
在大田条件下,设置小麦、玉米不同灌溉量和灌溉时期的组合模式,对低压微喷条件下冬小麦、夏玉米产量、周年水分利用效率、经济效益进行分析。结果表明,与传统漫灌相比,低压微喷灌溉可以提高水分利用效率、灌溉水分利用效率和作物千粒质量,延缓灌浆后期叶片SPAD值的下降速度;测墒补灌结合低压微喷模式(S3)作物周年产量与对照间差异不显著(P>0.05),但水分利用效率较对照显著提高32.8%(P<0.05),灌溉水分生产效率较对照显著提高54.8%(P<0.05),经济效益比对照提高10.5%。在此试验条件下,测墒补灌结合低压微喷(S3)为最优灌溉模式。

摘 要：
The field experiments with low pressure micro-sprinkling irrigation(LSPMSI)were conducted to evaluate the annual grain yield, water use efficiency and benefits under winter wheat and summer maize rotating system. In 2014-2015, different micro-sprinkling irrigation water applied at different stage of winter wheat and summer maize. The results showed that LSPMSI could improve water use efficiency(WUE)and irrigation water use efficiency(IWUE), increase thousand grain quality and delay the SPAD value decreased rate in late filling stage, compared with the flooding irrigation(CK). There was no significant difference(P>0.05)in grain yield between S3(combination technique of supplement irrigation based on testing soil moisture)with MSI and CK. However, the WUE and IWUE of S3 were higher 32.8%(P<0.05)and 54.8%(P<0.05)than CK, respectively, the economic benefit of S3 enhanced10.5% than CK. The S3 was optimized irrigation model in this experimental condition.
