为探索如皋市主要土壤类型优质专用小麦氮、磷、钾施入的最佳配比,进行了弱筋小麦平衡施肥试验。结果表明,肥料对小麦产量的影响效果为氮肥>磷肥>钾肥;在高氮的水平下,重视磷肥使用,氧、磷、钾配比为1∶0.75∶0.5时,产量最高,达8.60t/hm2;氮、磷、钾配比为1∶0.33∶0.45时,经济效益最高,最佳产量为7.15t/hm2。 In order to explore the best ratio of nitrogen, phosphorus and potassium for wheat with high quality and special quality of main soil types in Rugao, the balanced fertilization experiment of weak gluten wheat was carried out. The results showed that the effect of fertilizer on the yield of wheat was nitrogen fertilizer> phosphate fertilizer> potassium fertilizer. Under the condition of high nitrogen level, the fertilizer application was emphasized. When oxygen, phosphorus and potassium ratio was 1: 0.75: 0.5, the yield reached 8.60t / hm2. When the ratio of N, P and K was 1: 0.33: 0.45, the economic benefit was the highest, and the best yield was 7.15 t / hm2.
