不同玉米品种产量潜力的比较研究
Comparison of Yield Potential among Different Maize Varieties
摘要
Abstract
[Objective] To compare the yield potential among different maize varieties of Jundan 20, Zhengdan 958 and Denghai 605.[Method] With Jundan 20, Zhengdan 958 and Denghai 605 as test materials, the yield potential were discussed.And the changes of 1000-grain weight, ear number and seeds per ear of three maize variety were discussed.[Result] The growth period, sunshine duration and accumulated temperature of three maize varieties from big to small were in the order of Denghai 605, Zhengdan 958, Jundan 20.The? leaf area index, photosythetic production rate and grain filling rate firstly enhanced and then reduced as the growth satge prolonged .The values of three maize varieties from big to small were in the order of Denghai 605, Zhengdan 958 and Jundan 20.The yield, ear number and seeds per ear of three maize varieties from big to small were in the order of Denghai 605, Zhengdan 958 and Jundan 20.The 1000-grain weight of three varieties from big to small were in the order of Jundan 20, Zhengdan 958 and Denghai 605.[Conclusion] Under the current ecological condition of Huang-Huai-Hai, the proper maize varieties were Denghai 605 and Zhengdan 958.关键词
