摘　　要：为提高小麦化肥利用率,改进施肥方法,规范肥料配方,制定科学施肥方案,进行了小麦配方施肥化肥利用率试验。结果表明,配方施肥的小麦产量最高,达到436.90kg/亩,与其他处理相比差异显著。配方施肥比无磷、无钾、无氮和无肥处理分别增产17.58%、31.00%、83.66%、110.82%,显示养分缺失对产量影响显著。机械深施配方肥模式下,小麦对氮、磷、钾肥的利用率分别为43.81%、31.68%、58.14%。In order to improve the fertilizer utilization rate of wheat,improve the fertilization method,standardize the fertilizer formula and develop scientific fertilization scheme,experiment of fertilizer utilization rate of wheat for formula fertilizer was carried out.The results showed that the wheat yield with formula fertilizer was the highest,reaching 436.90kg/mu,which was significantly different from other treatments.Formula fertilization increased yield by 17.58%,31.00%,83.66%and 110.82%compared with no phosphorus,no potassium,no nitrogen and no fertilizer respectively,which indicated that nutrient deficiency had a significant impact on wheat yield.The utilization rates of N,P and Kwere 43.81%,31.68%and 58.14%respectively for mechanized deep fertilization of formula fertilizer.
