Abstract：Field experiment was conducted for studying the effect of nitrogen forms on the yield of Chinese cabbage and the accumulation of nitrate. The results showed that urea application could obtain higher yield than ammonia bicarbonate application, and compared with common urea, big granulated urea was more effective, obtaining higher yield and net yield. The amount of nitrate in inner leaves increased with the increasing rate of nitrogen fertilizer application, yet the content of nitrate kept at a certain amount...
