摘　　要：采用田间试验研究了含硝化抑制剂3,4-二甲基吡唑磷酸盐(3,4-dimethylpyrazolephosphate,DMPP)复合肥(ENTEC,12-12-17)对西瓜(CitrulluslanatusM.)、黄瓜(CucumissativusL.)生长和品质的影响。结果表明,含DMPP复合肥可以显著提高西瓜、黄瓜产量,与对照(普通复合肥)相比,分别提高6.50%(浙蜜1号)、44.55%(浙蜜2号)、8.40%(津春4号),均达到了显著性水平。西瓜、黄瓜的硝酸盐含量与对照相比,分别降低了2.42%(浙蜜1号)、10.70%(浙蜜2号)、27.44%(津春4号)。西瓜、黄瓜的糖分、可溶性固形物、VC、氨基酸、N等含量都明显提高,从而提高了营养品质。从总的趋势来看,含DMPP复合肥在西瓜浙蜜2号上的施用效果优于浙蜜1号。The nitrification inhibitor （3,4-dimethylpyrazole phosphate, DMPP）offers advantages over Dicyandiamide（DCD） and nltrapyrin. However, little is known about effects of DMPP formulated with fertilizer on the growth and nutritional quality of crops until recently. A field experiment was conducted to investigate the effects of new compound fertilizer （ENTEC, 12-12-17） with DMPP on growth and nutritional quality of watermelon （Citrullus lanatus M.） and cucumber （Cucumis sativus L.）. The results showed that ENTEC increased watermelon yield significantly by 6.50% （Zhemi 1）, 44.55%（Zhemi 2） and cucumber （Jinehu 4 ） yield by 8.40%. ENTEC also decreased nitrate content by 2.42%（Zhemi 1）, 10.70%（Zhemi 2） and cucumber （Jinchu 4） by 27.44%, In addition, ENTEC improved nutritional quality such as soluble sugar or solid, vitamin C, amino acid and N content in these two crops, hut compared to conventional compound fertilizer （Control）, different types of crops showed different responses to ENTEC, and ENTEC had better effect applied in Zhemi 2 than in Zhemi l. Above all, this com pound fertilizer with DMPP could effectively suppress conversion of NH4^＋ to NO2^- and had high rate of potassium, which may be the reason for ENTEC improving yield or nutritional quality.
