摘　　要：以芝麻品种豫芝DW607为指示品种,研究了机械种植膜下滴灌条件下最佳灌水量、氮磷钾施肥量及种植密度三因素耦合效应对豫芝DW607农艺性状和产量的影响。结果表明,种植密度为27万株/hm^2,每次灌水2.5 h,滴灌量为177.89 m3/(hm^2·h),施N 182.325 kg/hm^2、P2O577.074 kg/hm^2、K2O 30.399 kg/hm^2时,豫芝DW607的平均折合产量最高,为2 621.79 kg/hm^2。With sesame cultivar Yuzhi DW607 as the indicator variety,the effects of coupling effects of optimal irrigation amount,N,P,K fertilizer application amount and planting density suitable for mechanical planting and drip irrigation under film on the agronomic characters and yield of Yuzhi DW607 were studied. The results showed that the average equivalent yield of yuzhi DW607 was the highest,2 621.79 kg/hm2 when the planting density was 270 000 plants/hm2,each irrgation for 2.5 hours,the drip irrigation volume was 177.89 m3/(hm2·h),N 182.325 kg/hm2,P2O 577.074 kg/hm2,and K2O 30.399 kg/hm2 were applied.
