摘　　要：天达-2116是一种新型的植物生长调控剂,为明确天达-2116拌种对玉米的调控效应,以玉米品种兴黄单206为试材,在田间采用随机区组试验,研究了不同浓度天达-2116拌种对玉米生长发育、产量及品质的影响,结果表明,天达-2116拌种能够增强玉米植株长势,增加茎粗,提高玉米株高、穗位高,增加千粒重,提高玉米产量和品质,7.5 g/kg拌种处理的产量比对照增加691.9 kg/hm2,增产率达7.98%。天达-2116在玉米上适宜的拌种浓度应在5～7.5 g/kg之间。Tianda-2116 was a new plant growth regulator. In order to confirm the regulating effect of Tianda-2116 on maize, the experiment with random blocks was conducted to investigate the effects of seed-dressing with the different concentration Tianda-2116 on the growth, development, yield and quality of maize. The results showed that seed dressing with Tianda-2116 could enhance the growth, height, spike bit height, thousand corn weight and yield of maize. The application of 7.5 g Tianda-2116/kg maize had evident effect on the yield of maize. The yield of maize was increased by 691.9 kg/hm2 as compared with CK, with increase production rate of 7.98%. The feasible concentration of seed dressing with Tianda-2116 was 5-7.5 g/kg.
