摘要：

为明确天达-2116、好鲜收、复硝酚钠、芸苔素内酯4种植物生长调节剂对玉米生长发育、产量及品质调控作用，为四种植物生长调节剂在玉米上的应用提供依据。以兴单131为试验材料，采用浸种法在田间进行随机区组试验，结果表明，4种植物生长调节剂浸种能增强玉米植株长势，提高玉米产量及品质，其中天达2116效果较为明显，出苗率比对照提高11.1%，产量每公顷比对照增产850.4 kg，增产率达9.6%，增产效益显著，好鲜收、芸苔素内酯分别比对照增产7.9%和7.4%，复硝酚钠对玉米千粒重影响较大，比对照增加17.3 g，差异达极显著水平。天达-2116、好鲜收、复硝酚钠、芸苔素内酯4种植物生长调节剂可作为玉米浸种剂使用。

Abstract:

To confirm the regulating effect of the four plant growth regulators such as Tianda-2116, Haoxianshou, sodium nitrophenolate and brassinolide on growth, yield, and quality of maize, and to provide the basis for application of the four plant growth regulators in maize production. Xingdan-131 was selected as the test material. A presoaking technique was used to evaluate the effect of these plant growth regulators on growth, yield and quality of maize under the field conditions through random block design. The results showed that the four plant growth regulators could enhance the growth, yield and quality of maize. The application Tianda-2116 had a significant effect on the germination rate and yield of maize. After seed was pre-soaked with Tianda-2116 solution, germination rate of maize was increased 11.1% as compared with CK, and increase maize yield per hectare was 850.4 kg than CK, with increase rate of 9.6%. The use of Haoxianshou and brassinolide also markedly enhanced maize yield, which increased by 7.9% and 7.4% as compared with CK, respectively. Sodium nitrophenolate had an evident impact on thousand corn weight of maize, which was 17.3g higher than CK. Differences were statistical significance between sodium nitrophenolate treatment and CK. Tianda-2116, Haoxianshou, sodium nitrophenolate or brassinolide could used as seed soaking agent in maize production.
