摘  要:
试验通过对5个玉米品种的霜冻模拟试验和自然霜冻试验,利用目测法和离子外渗法得出:在选定的5个品种中农大108抗霜冻能力最强,陕单931抗霜冻能力最弱;温度越低、霜冻时间越长对玉米危害越大;越接近成熟的玉米植株抗霜冻能力越强。试验结果可为雁北地区玉米生产中品种选择提供参考。

摘  要:
In order to select maize varieties with strong frost hardiness,five maize varieties were chosen to compare ability of frost hardiness by suffering from nature frost and simulation frost experiment.The results showed that Nongda 108 had the strongest ability to freezing hardiness and Shandan 931 had the weakest ability to freezing hardiness among 5 maize varieties.The lower temperature and the longer frost lasted,the more serious damage maize would have.The nearer maize approaching maturity period,the stronger the maize ability to freezing hardiness would have.
