为了探究施用含有硝化抑制剂型水溶肥料对蔬菜品质与产量的影响,以温室黄瓜为对象,研究在农民习惯施肥量的基础上分别施用含有双氰胺(DCD)、吡啶的水溶肥对温室黄瓜产量及品质的影响.结果表明:与农民习惯施肥相比,含有DCD和吡啶的水溶肥分别可提高黄瓜产量5.57%和18.67%,并且除氨基酸外,二者均可明显提升黄瓜的品质.施用含有DCD和吡啶的水溶肥的处理能显著降低黄瓜中硝酸盐含量,降幅分别为21.59%,34.85%;吡啶可增加黄瓜中维生素C、可溶性糖含量;含DCD、吡啶的水肥处理下,黄瓜中16种氨基酸总含量分别为14.86×10 -2, 18.34×10 -2mg/g,显著低于农民习惯施肥处理,降幅分别为39.15%,24.98%,其中天冬氨酸、谷氨酸、丝氨酸均下降显著,且含DCD的处理黄瓜中甘氨酸含量也显著下降.与DCD相比,含吡啶的水溶肥更有益于黄瓜增产以及品质的提升.
Effects of Soluble Fertilizer with Nitrification Inhibitor on Yield and Quality of Cucumber in Greenhouse
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 cu-cumber 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 treat-ments,content of Σ16 kinds amino acids were 14.86 ×10 -2,18.34 ×10 -2mg/g respectively,were significantly lower than fertilization treatment by 39.15% and 24.98%,especially aspartic acid,glutamic acid and serine.Appli-cations of the soluble fertilizer with DCD also decreased the content of glycine in cucumber.Compared with applica-tion of DCD,the nitrapyrin application was better for increasing the yield and improving the quality of cucumber in greenhouse.
