玉米测土配方施肥模式肥料利用率试验

An Experiment of Fertilizer UtilizationEfficiency of Soil Testing and FormulatedFertilization Model for Corn

测土配方施肥模式下玉米肥料利用率试验研究结果表明,N肥利用率30.3%、K肥利用率54.9%,接近全国平均值;P肥利用率9.5%较低,因此还需要改进技术,提高P肥利用率。

Through the experimental study on the fertilizer utilization efficiency of corn under the soil testing and formulated fertilization model,the results show that the utilization rate of N fertilizer is 30.3%and that of K fertilizer is 54.9%,which is close to the national average;the utilization rate of P fertilizer is 9.5%lower,and the technology needs to be improved,so as to improve the utilization rate of P fertilizer.
