摘要
[目的]探索贞丰县下等肥力地小麦氮、磷、钾肥最佳施肥配比.[方法]通过小麦"3414"肥料效应田间试验,对不同施肥处理的小麦产量进行分析比较,以确定最佳施肥配比.[结果]施用不同配比的氮、磷、钾肥对小麦的农艺性状和产量有不同的影响,当施肥量为N 390 kg/hm2,P2O5 750 kg/hm2,K2O 124.5 kg/hm2 时,小麦的产量最高,为 4 971.0 kg/hm2,较未施肥区增产 2 131.5 kg/hm2.[结论]在与该试验相同肥力条件的下等肥力地种植小麦,推荐最佳施肥量为:N 390 kg/hm2,P2O5 750 kg/hm2,K2O 124.5 kg/hm2.
Abstract
[Objective]The aim was to explore the optimal fertilization ratio of nitrogen,phosphorus and potassium fertilizers for wheat in low fertility fields of Zhenfeng county.[Method]Through field experiments on the"3414"fertilizer effect of wheat,the yield of wheat under different fertilization treatments was analyzed and compared to determine the optimal fertilization ratio.[Result]The application of different ratios of nitrogen,phosphorus,and potassium fertilizers had different effects on the agronomic traits and yield of wheat.When the fertilization amount was N 390 kg/hm2,P2O5750 kg/hm2,and K2O 124.5 kg/hm2,the wheat yield was the highest,with a yield of 4 971.0 kg/hm2,which was 2 131.5 kg/hm2 higher than that in the unfertilized area.[Conclusion]Under the same fertility conditions as the test,the recommended optimal fertilization amounts for wheat cultivation are N 390 kg/hm2,P2O5750 kg/hm2,and K2O 124.5 kg/hm2.
