摘要

To assess the effects of N fertilizer ammonium sulphate nitrate [(NH4)2SO4 plus NH4NO3;ASN] with the new nitrification inhibitor (NI) 3, 4-dimethylpyrazole phosphate (DMPP)(ASN+DMPP) on yield, nitrate accumulation, and quality of cabbage (Brassica campastrisL. ssp. pekinesis), two field trials were carried out under various soil-climatic conditions in Jinhua City and Xinchang County, Zhejiang Province of China in 2002.Results showed that DMPP could increase the mean yield by + 2.0 t ha-1 in Jinhua, +5.5 t ha-1 in Xinchang, decrease NO3--N content by -9.4% in Jinhua, -7.3% in Xinchang and improve nutritional quality by increasing vitamin C (VC), soluble sugar, K, Fe, Zn contents significantly.
