摘  要:
以番茄为试验材料,设置固定隔沟灌和交替隔沟灌两种灌溉方式,每种灌溉方式设置2个灌水水平和2个施氮水平,共8个处理,分别测试每个处理番茄的产量、平均单果重、水分利用效率和品质,最后采用多指标综合评价方法提出优化的水氮耦合模式,结果表明:产量和水分利用效率最优的水氮耦合模式为T8(AFI),推荐灌水量为1 100m3/hm2,施氮量为150kg/hm2;品质最优的水氮耦合模式为T6(AFI),推荐灌水量为1 300m3/hm2,施氮量为150kg/hm2;综合最优的水氮耦合模式为T6(AFI),推荐灌水量为1 300m3/hm2,施氮量为150kg/hm2。

摘  要:
A study is conducted by setting up two irrigation methods of fixed furrow irrigation and alternative furrow irrigation.Each irrigation method includes two water levels and two nitrogen levels,and a total of eight treatments.The tomato yield,average fruit weigh,water use efficiency and quality of each treatment are tested,and finally the optimal water-nitrogen coupling mode is proposed through the multi-index comprehensive evaluation method.The results show that:T8(AFI)is the optimal water-nitrogen coupling mode with the best yield and water use efficiency(the recommended irrigation water is 1 100m3/hm2,N applied is 150m3/hm2);T6(AFI)is the optimal water-nitrogen coupling mode with the best quality(the recommended irrigation water is 1 300m3/hm2,N applied is 150m3/hm2);and T6(AFI)is the optimal comprehensive water-nitrogen coupling mode with recommended irrigation water of 1 300m3/hm2 and N applied of 150m3/hm2.
