Abstract: The effect applications of the soluble fertilizer with dicyandiamide(DCD) or nitrapyrin on yield and quality of cucumber in greenhouse were studied.The results showed that,compared with the fertilization treatment(FP),the applications of DCD and nitrapyrin treatments of In-1 and In-2 could increase the yield of cucumber by 5.57% and 18.67%.Applications of the soluble fertilizer with DCD and nitrapyrin could improve the quality of cucumber obviously except amino acids,reduced the content of nitrate significantly by 21.59%,34.85% in cucumber respectively,and increased the content of VC and soluble sugar.With the addition of DCD and nitrapyrin treatments,content of Σ16 kinds amino acids were 14.86×10-2,18.34×10-2 mg/g respectively,were significantly lower than fertilization treatment by 39.15% and 24.98%,especially aspartic acid,glutamic acid and serine.Applications of the soluble fertilizer with DCD also decreased the content of glycine in cucumber.Compared with application of DCD,the nitrapyrin application was better for increasing the yield and improving the quality of cucumber in greenhouse.

Key words: Cucumber in greenhouse, DCD, Nitrapyrin, Quality of cucumber, Amino acid
