摘　　要：2014年对参加湖北省夏玉米(Zea mays)区域试验的10个玉米品种进行化调矮化药效试验。结果表明,化调矮化栽培新技术能显著降低玉米植株的株高和穗位高,品种间药剂矮化效果有明显差异;对玉米干子粒产量有明显影响,多数品种表现子粒减产,极少数品种表现为子粒增产,不同品种表现不同。由此,在玉米生产上大面积应用化调矮化栽培新技术要慎重,对不同品种要区别对待,要特别重视品种特性和施药方法,降低生产风险,提倡安全生产。Thechemical regulated dwarfing and efficacy tests were applied on 10 maize（Zea mays） varieties which took part in the summer maize regional testing of Hubei province in 2014. The results showed that the chemical regulated dwarfing technology could significantly reduce the height of maize and its ear position,and the dwarfing effects were obviously different among maize varieties.This technology also had significant effects on the dried grain yields of maize,of which the most varieties displayed increasing productions and a few varieties displayed decreasing productions. So,we must be carefully to widespread applying the new chemical regulated dwarfing technology in a large area of maize cultivation,and should take different measures for different varieties. In order to reduce the production risk or promote safe production,we should pay special attention to their variety characteristic and the application methods.
