优化施肥对小麦秸秆还田下玉米产量和肥料利用率的影响
Effects of Optimized Fertilization on Maize Yield and Fertilizer Utilization under Wheat Straw Returning
摘要:
为摸清小麦秸秆还田下常规施肥夏玉米氮肥、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夏玉米氮磷钾肥料利用率试验。通过试验,得出优化施肥处理比常规施肥处理平均肥料利用率提高6.84个百分点,效果显著。同时优化施肥较常规施肥产量提高43.7 Kg/亩,提高了7.26%,说明优化施肥在提高肥料利用率的同时,也提高了产量。
Abstract:
In order to find out the current utilization rate of nitrogen, phosphorus and potash fertilizers of summer maize under conventional fertilization and optimize the effect of fertilization to improve the utilization rate of nitrogen, phosphate and potash fertilizers, a test of summer maize nitrogen, phosphorus and potassium fertilizer utilization rate was conducted in Huimin County, Binzhou City. Through experiments, it is concluded that the average fertilizer utilization rate of the optimized fertilization treatment is increased by 6.84 percentage points compared with the conventional fertilization treatment, and the effect is remarkable. At the same time, the optimized fertilization yield is increased by 43.7 Kg/mu, which is 7.26% higher than that of the conventional fertilization. At the same time, it also increased the production.
