摘要
选择适宜机收籽粒的玉米品种是实现玉米全程机械化的重要条件。玉米生理成熟期籽粒含水率高、后期脱水速率慢以及成熟后田间站秆性状差是制约玉米直收籽粒的重要原因。通过比较12个玉米品种在生理成熟期的籽粒产量、籽粒含水率以及生理成熟后籽粒脱水速率和倒伏倒折率、籽粒霉变率等田间站秆性状指标,结果发现:迪卡653和C1210两个玉米品种比较适宜河北东部旱作区直收籽粒,可作为苗头品种进一步应用验证。
The selection of maize varieties suitable for mechanical harvesting was an important condition for full mechanical harvesting.The high moisture content of maize grain during the physiological ripening period,the slow dehydration rate in the late stage,and the poor stalk traits in the field after maturity are important factors that restricting direct seed harvesting.The grain yield,grain moisture content,grain dehydration rate,lodging rate,grain mildew rate and other field stalk traits of12 maize varieties at physiological maturity were compared in this study.The results showed that the varieties Dika 653 and C1210 are more suitable for mechanical harvesting of grain directly in the dry farming area of eastern Hebei province,which can be used as promising varieties for further verification.
