| 摘 要： | 2015~2017年在江苏盐城市大丰区和连云港市赣榆区,开展5组机械粒收试验与示范,对参试的34个品种、75个品次收获期子粒含水率、破碎率、杂质率和产量损失率数据分析。结果表明,破碎率高、损失率大是该区域玉米机械粒收存在的主要质量问题,收获时子粒含水率偏高是导致破碎率高的主要原因之一。通过对参试品种玉米产量和收获期子粒含水率分析,以当年参试品种平均产量和收获期平均子粒含水率为指标,应用双向平均作图法,初步筛选出产量高、收获期含水率低的迪卡517、京农科728、泽玉8911和泽玉501,推荐为该区域适宜机械粒收品种。

| Abstract: | To popularize the technology of maize mechanical kernel harvest in Jiangsu province, five sets of harvest experiments were conducted in Dafeng district of Yancheng city and Ganyu district of Lianyungang city from 2015 to 2017. The results showed that the high grain broken rate and high loss rate are the two main problems of maize mechanical kernel harvest in this area, and the high grain moisture content at harvest is the main reason of high grain broken rate, which can be effectively solved through planting suitable varieties for mechanical kernel harvest. In this study, we analyzed the average yield and the average grain moisture content at harvest by bi-directional average method, and then screened four maize cultivars, that is, Dika517, Jingnongke728, Zeyu8911 and Zeyu501, suitable for mechanical kernel harvest in this region. |
