摘要
为筛选出适合唐山地区种植的春播稀植玉米品种,2014-2017年,唐山市农作物种子站对参试的37个玉米品种在唐山市所辖7个试验基地开展49 500株/hm2组别的区域试验和生产试验.结合品种安全性检测、专家田间实地考察等结果,共筛选出7个品种推荐通过了河北省品种审定,2017-2020年累计推广面积56 000 hm2,平均产量较'先玉335'增加2 368.5 kg/hm2.为全国不适宜种植密植玉米品种的区域提供了成功范例,同时也为国家玉米试验在本地组别的设定提供了参考依据.
Abstract
In order to screen out spring sowing sparse maize varieties suitable for planting in Tangshan area,from 2014 to 2017,Tangshan Crop Seed Station conducted regional trials and production trials of 37 maize varieties participating in 49 500 plants/hm2 groups in 7 test bases under Tangshan City.Combining with the results of vari-ety safety testing and field visits by experts,a total of 7 varieties were screened out and recommended to pass the variety approval in Hebei Province.The accumulated planting area from 2017 to 2020 is 56 000 hm2,with an aver-age yield increase of 2 368.5 kg/hm2 compared with'Xianyu 335'.It provides a successful example for the areas that are not suitable for planting dense corn varieties in the country,and also provides a reference for the setting of national corn experiments in local groups.
