Abstract
Taking rape as material,pot experiment was conducted to investigate the effect of boric acid and DCD dual inhibitors slow-release fertilizers on yield and nitrogen use efficiency of rape.The results showed that both urease inhibitor and nitrification inhibitor could effect the output of rape.The output rate increased 20.00%~30.33%,compared with normal urea.It reached the highest yield when the concentration of boric acid,dicyandiamide was 5%,increased 30.33%.Application of inhibitors of rape nitrogen use efficiency generally between 40.00%~62.27%.Among them when the concentration of boric acid,dicyandiamide were all 5%,nitrogen use efficiency as high as62.27%,31% higher than common urea.Every other inhibitors slow-release fertilizer nitrogen utilization efficiency were significantly higher than the normal urea treatment,compared with the normal urea,generally between16.00%~30.99%.The research had offered the scientific theoretical foundation for making slow controlled release fertilizer,in which increasing crop production,improving effective nitrogen plain use efficiency,increasing economic efficiency,decreasing the environmental pollution,and reasonable fertilization.
