优化施肥对冬小麦产量和肥料利用率的影响
Effects of Optimized Fertilization on Wheat Yield and Fertilizer Utilization
摘要:
为摸清常规施肥下冬小麦氮肥、磷肥和钾肥的利用率现状和优化施肥提高氮肥、磷肥和钾肥利用率的效果,在滨州市惠民县进行冬小麦氮磷钾肥料利用率试验。通过试验,得出氮肥是影响小麦产量的主要因素,磷次之,钾对小麦产量影响最小;优化施肥氮、磷、钾肥利用率比常规施肥情况下的氮、磷、钾肥利用率提高了6.88%,小麦产量提高8.90%。
Abstract:
In order to find out the current utilization rate of nitrogen, phosphorus and potassium fertilizers for winter wheat under conventional fertilization and optimize the effect of fertilization to improve the utilization rate of nitrogen, phosphorus and potassium fertilizers, a winter wheat N, P and K fertilizer utilization experiment was carried out in Huimin County, Binzhou City. Through experiments, it is concluded that nitrogen fertilizer is the main factor affecting wheat yield, followed by phosphorus, and potassium has the smallest effect on wheat yield; the optimized fertilizer N, P, and K fertilizer utilization ratio is increased by 6.88% compared with conventional fertilizer application, wheat production increased by 8.9%.
