摘　　要：通过田间试验研究了氮肥硝化抑制剂2-氯-6-三氯甲基吡啶对甜玉米农艺性状、产量和农学效应及甜玉米种植效益的影响。结果表明,施用2-氯-6-三氯甲基吡啶能够有效提高甜玉米产量和改善农艺性状,但与施肥模式及甜玉米品种有关,其中鲜甜5号玉米在一次性施肥配施2-氯-6-三氯甲基吡啶条件下增产19.2%,华美甜8号玉米在分次施肥配施2-氯-6-三氯甲基吡啶条件下增产3.4%,而且鲜甜5号和华美甜8号玉米在配施2-氯-6-三氯甲基吡啶条件下穗长、穗直径、秃尖长及秃尖率得到明显改善。说明施用2-氯-6-三氯甲基吡啶能够提高氮肥的偏生产力,提高甜玉米种植效益。Two field experiments were carried out to investigate the effects of nitrogen fertilizer nitrification inhibitor, 2-chloro-6-trichloromethyl pyridine, on agronomic characters, yield, partial fertilizer productivity and planting benefits of sweet corn. Results showed that application of 2 - chloro - 6 - trichloro methyl pyridine can effectively improve the yield and agronomic characters of sweet corn, but the effects were different with fertilization modes and sweet corn varieties, compared with the non nitrification inhibitor treatment, the yield of ＇fresh sweet No. 5＇ increased by 19.2% under single basal fertilization, and ＇hua mei tian No. 8＇ increased by 3.4% under split application. However, the agronomic characters of ear length, ear diameter, barren tip length and rate improved significantly. The application of nitrification inhibitor, 2 - chloro - 6 - trichloro methyl pyridine, can increase the partial productivity of nitrogen fertilizer, and improve the benefits of sweet corn planting.
