| 摘 要： | 通过田间试验,研究了ASI法推荐施肥、超高产攻关田经验施肥和农民习惯施肥对超高产夏玉米叶面积指数、干物质积累、养分积累量及产量与经济效益的影响,结果表明:夏玉米施肥处理显著增产9.50%~18.84%;ASI法推荐施肥与超高产攻关田经验施肥的产量无显著差异,但均比农民习惯施肥显著增产,增产率分别为6.62%和8.53%;氮、磷、钾肥配施增加了夏玉米叶面积指数和生物重,促进了植株对氮、磷、钾养分的吸收积累。ASI法推荐施肥处理的纯收益和产投比最佳,对超高产夏玉米有较好的增产、增收效应。

| Abstract: | Field experiment was conducted to study the effects of ASI recommended fertilization（ARF）,superhigh-yielding experienced fertilization（SHF） and peasants＇ customary fertilization（PCF） on the leaf area index,biomass,plant nutrient accumulation,yield and economic benefit of superhigh-yielding summer maize.The results showed that fertilization could obviously increase maize yield by 9.50%~18.84%.The maize yields in treatments ARF and SHF were not obviously different,but they were increased respectively by 6.62% and 8.53% in comparison with that in treatment PCF.The combined application of N,P and K fertilizer could significantly increase the leaf area index and biomass of summer maize,and promote the accumulation of N,P and K nutrient in the plants.ARF obtained the best net income and ration of output to input,and it had preferable yield-increasing and income-increasing effects on superhigh-yielding summer maize. |
