Environmental Effect of Chemical Fertilizer Adding Different Inhibitors under Open Field Conditions
Chemical fertilizer adding urease/nitrification inhibitors can improve utilization rate of fertilizer and protect ecological environment.The environmental effect of different kinds and content of inhibitors adding in chemical fertilizer under peanut growing conditions in brown soil were studied in this paper.The results indicated that compared with CK,urease inhibitor increased soil available nitrogen by 7.0%~15.0% and nitrification inhibitor increased soil available phosphorus by 6.4%~35.3%.In the meantime,urease activity and catalase activity increased by5%~15% and 10%~30%,respectively.No soil acidification and salinization were observed in the experiment.The test also demonstrated chemical fertilizer adding different inhibitors increased the yield of peanut by 2.06%~11.65%.Among which,0.15% 3,5-Dimethyprazole (DMP) deserved to be promoted in the practice.
