    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 1.3kg/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。

    Abstract:

    This research evaluated the effect of fertilizer recommendation method of nutrient expert system(NE)on rice yieldand nutrient use efficiency in Hubeiprovince.Totally 42 experiments on rice growth were conducted during 2013 tO2017.InGuangshuicounty,compared with farmer’spractice,the NE recommendation significantly reduced N application rateby18.0%,but increased P 2O5 and K2O rate by 23.9% and8.9%,respectively,the rice yield with NE recommendationincreased by1.4%,which has no significantdifferences.In Chibicounty,the NE recommendation significantly reducedN,P2O5 and K2O application rate by8.8%,32.9% and44.1%,respectively,the rice yield with NE recommendation increased by 6.9% than farmer’spractice,which has no significantdifferences.The average agronomic efficiencies ofN, P2O5 and K2O were12.5,9.5 and 1.3kg/kg,and fertilizer use efficiency were39.8%,6.5% and27.9%,respectively.NErecommended fertilization for rice could promote the absorption and accumulation ofN,P and K ofrice,improve yield andincome,and nitrogen fertilizer use efficiency aswell,which is worthy of popularization and application.
