Abstract

Through pot experiment, the results showed that the nitrate accumulation in rape increased if Nitrogen fertilizer(N), Organic Manure(OM), or OMN fertilizer was supplied. And compared to Urea, OM was better in the control over rape’s nitrate accumulation. Rape’s nitrate accumulation increased with fertilization increasing, including OM.
