IFC增效微肥对小白菜产量和硝酸盐积累的影响

Abstract

Abstract: A plot experiment was conducted in Rugao demonstration base in a region of highly sandy soil along the Changjiang River in Jiangsu Province to investigate effects of IFC-microelement fertilizer on yield and nitrate accumulation of Chinese cabbage. The plots in the experiment all received the same rate of phosphorus and potassium but different rate of nitrogen, combined with or without additional IFC-microelement fertilizer (30 kg·hm ^-2 ). The experiment shows that the application of IFC-microelement fertilizer at an appropriate rate increased yield and nitrogen accumulation of the crop but decreased nitrogen and nitrate contents in the crop, and nitrogen contamination of the soil and ground water as well.

Key words: IFC-microelement fertilizer, Chinese cabbage, nitrate
