为黄壤旱坡地夏玉米合理施肥提供依据，2008-2012年在黔中夏玉米连作区进行田间定位施肥，分析不同施肥模式（农民习惯施肥与优化施肥）黄壤旱坡地玉米产量及肥料效益的差异。结果表明：2008-2012年期间，优化施肥较农民习惯施肥玉米平均增产23．8％，氮、磷、钾肥料利用率分别提高2．7％、4．7％和3．9％。结论：优化施肥提高黄壤坡地玉米产量，促进氮磷钾的吸收利用，具有增产增收效应，肥料利用效率较高，可作为黄壤旱坡地区夏玉米推荐施肥方法推广应用。

In order to provide a reference for rational fertilization of maize on yellow soil in sloping land,effects of different fertilization mode on yield of summer maize and fertilizer efficiency in yellow soil on sloping farmland with long-term fertilization experiment in central Guizhou were analyzed from 2008 to 2012.The results showed that maize yield increased by 23.8% with optimized fertilization.The average efficiency of nitrogen,phosphorus,and potassium fertilizer increased by 2.7%,4.7% and 3.9%, respectively.It could be concluded that optimized fertilization improved nutrient absorption,therefore increased yield of summer maize.The optimized fertilization treatment had the highest fertilizer efficiency, therefore,it could be implemented for summer maize on yellow soil in sloping land.
