| 摘 要： | 为评价中稻养分专家系统(Nutrient Expert,NE)推荐施肥对中稻产量效应、养分利用率的影响,于2013～2017年期间在湖北省开展了42个试验,并对结果进行了分析。广水市推荐施肥NE比习惯施肥FP施氮肥低18.0%,磷肥高23.9%和钾肥高8.9%情况下,中稻增产1.4%,差异不显著。赤壁市推荐施肥NE比习惯施肥FP施氮、磷和钾肥分别减少8.8%、32.9%和44.1%的情况下,中稻增产6.9%,差异不显著。中稻氮、磷和钾肥平均农学效率分别为12.5、9.5和1.3 kg/kg,中稻氮、磷和钾肥平均当季利用率分别为39.8%、6.5%和27.9%。水稻养分专家系统推荐施肥促进了水稻对氮磷钾养分的吸收和利用,达到增产增收效果,氮肥利用效率也高于全国平均水平,可在中稻种植区推广应用。
