吉林省西部地区滴灌条件下宜机械粒收玉米品种筛选

确定宜机械粒收的玉米品种是构建吉林省西部旱作补灌区玉米丰产增效技术模式的重要内容之一。2018年和2019年在吉林省西部地区开展滴灌条件下宜机械粒收玉米品种的筛选试验,测定38个玉米品种的收获子粒含水率和产量,并按玉米子粒含水率和产量水平采用双向平均法作图进行品种分类。结果表明,本研究初步筛选出5个滴灌条件下宜机械粒收玉米品种,分别是迪卡159、福莱77,稷秾108、吉农大889和优迪919。根据品种综合性状分析,吉农大889较优,其次为迪卡159,可以作为适宜吉林省西部滴灌条件下丰产高效栽培的推荐品种。

Screening of Maize Cultivars Suitable for Mechanical Kernel Harvest under Drip Irrigation in Western Areas of Jilin Province

The determination of maize varieties suitable for mechanical kernel harvest is one of the important contents for constructing the technical model of high yield and increasing efficiency of maize in the dry irrigation area in western areas of Jilin province. From 2018 to 2019 the maize cultivars suitable for mechanical kernel harvest test were carried out under drip irrigation in western regions of Jilin province. The harvest grain moisture content and yield for 38 maize cultivars were tested. According to grain moisture content and yield level, the two-way average method was used to make graphs for classifying cultivars. The results showed that 5 maize cultivars including Dika159, Fulai 77, Jinong108, Jinongda889 and Youdi919 suitable for mechanical kernel harvest under drip irrigation are preliminarily selected. According to the cultivars analysis on comprehensive characters, it is found that Jinongda889 was the best, followed by Dika159, both can be used for recommended cultivars for high yield and high efficiency cultivation under drip irrigation in western areas of Jilin province.
