摘要
介绍了玉米杂交种新科910的选育思路及其过程。针对该品种植株高有倒伏的风险,探讨不同抗倒剂在不同的喷施时间,对玉米农艺性状和产量的影响。结果表明：几种化控试剂均能有效降低株高和穗位高,化控试剂“金玉丰”和“玉米四宝”,在叶龄8-9片叶喷施降秆增产效果最好。
The breeding thought and process of Maize Hybrid Xinke 910 were introduced in this paper. Because there was the possibility that Xinke 910 could lodged ,effects of different lodging-resistance agents and spraying stages on the agronomic characters and yield of Xinke 910 were investigated. The results showed that the application of lodging-resistant agents could shorten the plant height and ear height. The best spraying time of ＂Jinyufeng＂ and ＂Maize Sibao＂ was at seven to eight leaf stages.
