Analysis on the Fertilizer Utilization Rate experiment of Maize in Yangcheng County
In order to understand the fertilizer utilization rate of maize in Yangcheng County,optimize fertilizer structure,improve fertilizer utilization efficiency and reduce fertilizer input,field experiments were carried out.According to the implementation plan,the experimental field was rationally arranged,and the maize variety Qiangsheng 192 was used in the experiment.5 treatments were set up for 3 repetitions,and the 5 treatments were respectively nitrogen free zone,phosphorus free zone,potassium free zone,nitro-gen,phosphorus and potassium free zone.In the course of the experiment,field management should be done according to the scheme,and the yield should be measured scientifically after the experiment.The results showed that the utilization rates of nitrogen fertilizer,phosphate fertilizer and potassium fertilizer in Yangcheng County were 41.50%,17.43%and 54.85%.
