Abstract

Appling molybdenum fertilizer could remarkably reduce accumulation of nitrate in lettuce and you-mai vegetable no matter which pattern of fertilization,basal-dressing and top-dressing.Nitrogen,phosphorus and potassium fertilizers should be used inproper proportions fertilizing for leaf-vegetables and should be used asbasic manure;Appling only nitrogen manure was sure to cause accumulation of nitrate easily.
