不同施肥处理对夏玉米产量及肥料利用率的影响
Effect of Different Fertilization Treatments on Yield and Fertilizer Utilization Rate of Summer Maize
摘要
Abstract
The experiment used the main summer maize variety Denghai 605 as the test object,in order to explore the effect of different fertili-zation treatments on soil physicochemical properties,nitrogen,phosphorus and potassium contents in straw and grains,corn yield and econom-ic coefficient,and calculated the utilization rates of nitrogen,phosphorus and potassium fertilizers for summer maize.The results showed that different fertilization treatments reduced soil pH and organic matter,alkalihydrolyzed nitrogen,and available phosphorus;total nitrogen,phos-phorus,and potassium increased the yield of summer maize grains and straw,as well as the nutrient absorption of grains and straw.In this ex-periment,the utilization rate of nitrogen fertilizer,phosphorus fertilizer and potassium fertilizer were 32.96%,14.25%and 41.67%,respec-tively,and the utilization rates of comprehensive fertilizer was 40.34%.Economic coefficient of maize was 0.47-0.51.关键词
