冬小麦肥料利用率试验初报

Preliminary Report on Fertilizer Utilization Rate of Winter Wheat

为掌握冬小麦对氮肥、磷肥、钾肥的利用状况,采用对比试验的方法,开展冬小麦肥料利用率田间试验。试验结果表明:氮磷钾合理配合施用(18∶16∶6)能有效提高冬小麦产量,氮肥、磷肥、钾肥的利用率分别为40.59%,25.37%和35.04%。

In order to understand the utilization status of nitrogen fertilizer,phosphate fertilizer and potassium fertilizer in winter wheat,the comparative test method was used to carry out the field test of the fertilizer utilization rate of winter wheat.The test results show that:The reasonable combined application of nitrogen,phosphorus and potassium(18∶16∶6)can effectively improve the yield of winter wheat,and the utilization rate of nitrogen fertilizer,phosphate fertilizer and potassium fertilizer are 40.59%,25.37%and 35.04%,respectively.
