摘要

Abstract

With a simulated rainfall equipment,the pattern of soil nitrogen loss under a same rainfall intensities was studied by plot test on sloping surfaces.Results showed that under the same conditions,the different kind of fertilizer had significant difference.Compared with ammonium bicarbonate and urea,the controlled-release urea could reduce the loss of nitrogen.In the same situation,the amount of total nitrogen,ammonium nitrogen in runoff and total nitrogen in sediment was given as follows: Ammonium bicarbonate urea sulphur coated control-released urea resin coated control-released urea.The amount nitric nitrogen loss in runoff was given as follows: Urea ammonium bicarbonate sulphur coated control-released urea resin coated control-released urea.
