利用3个春玉米品种，在河北省宣化县的21个试验点上进行了“3414”氮磷钾肥料试验，以期研究春玉米肥料利用率及其配方施肥技术。试验结果表明：肥力不同肥料的利用率也不同，肥力越高利用率越低，该县春玉米的氮磷钾施肥利用率分别为30．3％、18．7％和29．6％。经进一步模拟与分析，建立了宣化县耕地土壤主要养分指标体系和玉米氮磷钾施肥推荐指标体系。这一研究结论不但为该县的春玉米高产施肥，也为同类地区的春玉米高产施肥提供了依据。
利用3箇春玉米品種，在河北省宣化縣的21箇試驗點上進行瞭“3414”氮燐鉀肥料試驗，以期研究春玉米肥料利用率及其配方施肥技術。試驗結果錶明：肥力不同肥料的利用率也不同，肥力越高利用率越低，該縣春玉米的氮燐鉀施肥利用率分彆為30．3％、18．7％和29．6％。經進一步模擬與分析，建立瞭宣化縣耕地土壤主要養分指標體繫和玉米氮燐鉀施肥推薦指標體繫。這一研究結論不但為該縣的春玉米高產施肥，也為同類地區的春玉米高產施肥提供瞭依據。

Based on result of ＇3414＇ fertilization experiment effect for three varieties of spring maize in 21 experiment sites of Xuanhua county, Hehei province, techniques for fertilization by soil testing and fertilizer use efficiency of spring maize were studied. The results showed that fertilizer use efficiency was determined by soil fertility, higher fertilizer use efficiency was got in lower fertility soil, and NPK fertiliz- er use efficiencies of spring maize in Xuanhua county were 30.3%, 18. 7% and 29.6%, respectively. By further simulation and analysis, index system of soil fertility and recommendation index system of NPK fertilizer in Xuanhua county were established, which is basis not only for high yield of spring maize by fer- tilization in Xuanhua County, but also for high yield of spring maize by fertilization in other regions of the same kind.
