"控失"型复合肥在宿州冬小麦上应用效果初探

[目的]研究冬小麦上施用＂控失＂型复合肥的肥效和经济效益。[方法]实施小麦施用不同肥料的田间试验。[结果]＂控失＂高肥区产量与等养分普通基施区相比增产2.5%;＂控失＂低肥区与普通基施区平产。＂控失＂型复合肥区小麦中后期生长发育表现突出,肥力充足,肥效优于普通肥;氮肥基施、拔节期追施各50%,可以提高肥料利用率,与普通基施区相比产量增加7.7%,纯收益最高;不同施肥方式的经济效益分析显示：＂控失＂型复合肥的投入产出比较高,＂控失＂低肥区的经济效益更加明显,投入产出比最高,纯收入比普通基施区多315.0元/hm~2。[结论]＂控失＂型复合肥控失效果显著,值得大面积推广应用。
