中文摘要:

为明确小麦养分专家系统推荐施肥效果，通过田间试验比较分析了小麦养分专家系统和Agro Services International Inc (ASI)法推荐施肥下不同质地潮土冬小麦产量、经济效益、养分吸收积累及肥料利用效率的差异。结果表明，在粘壤质和砂壤质潮土上，冬小麦施肥分别增产6.05%~21.92%和8.67%~31.49%；小麦养分专家系统推荐施肥较农户习惯施肥分别增产4.91%和7.35%，增收10.30%和8.42%；ASI法推荐施肥较农户习惯施肥分别增产4.63%和4.98%，增收12.18%和5.77%。小麦养分专家系统推荐施肥的氮、磷、钾肥农学效率分别为6.26、5.31和6.71 kg·kg^-1，氮、磷、钾肥料利用率分别为26.06%、15.28%和43.41%。小麦养分专家系统推荐施肥促进了冬小麦对氮磷钾养分的吸收和利用，具有明显的增产增收效应，肥料利用效率也高于全国平均水平，可在潮土区推广应用。

英文摘要:

In order to realize the effects of scientific fertilization in winter wheat, field experiments were conducted to study the effects on yield, nutrient accumulation, economic benefit, and fertilizer use efficiency of winter wheat of fertilization recommended by nutrient expert and agro-services international inc (ASI) for wheat. The results showed that yield was increased by 6.05%~21.92% and 8.67%~31.49% in the clay soil and fluvo-aquic soil, respectively by applying fertilizer. Compared with the conventional fertilizer application,nutrient expert recommended fertilization for wheat increased grain yield by 4.91% and 7.35% and economic benefit by 10.30% and 8.42%, respectively; fertilization recommended by ASI increased grain yield by 4.63% and 4.98% and economic benefit by 12.18% and 5.77%, respectively. The average agronomic efficiency of N, P₂O5 and K₂O were 6.26, 5.31 and 6.71 kg·kg^-1, and fertilizer use efficiency were 26.06%, 15.28% and 43.41%, respectively，based on nutrient expert recommended fertilization for wheat. Nutrient expert recommended fertilization for wheat could promote the absorption and accumulation of N, P and K of winter wheat, improve yield and income obviously, and fertilizer use efficiency as well. This nutrient expert recommended fertilization for winter wheat is worthy of popularization and application.
