摘要
全球气候变暖导致的极端高温天气,对玉米生长发育和产量构成产生严重的不利影响。探讨高温条件下玉米热害产生的原理和方式,对玉米生产实践具有现实的指导意义。分析了高温对玉米生产的影响途径及方式,并提出了选用耐热抗逆品种、进行耐热性锻炼、改善农田小气候、人工授粉、调整播期等适当的防御措施,可以缓解高温对玉米生产的危害。
Extremely high temperature caused by global warming has great adverse influence on maize growth, development and yield components. In this paper, the mechanisms and patterns of high temperature damage to maize were reviewed and proper precautions were put forward, e. g. selection of heat tolerant varieties, heat hard- ening, farm microclimate improvement, artificial pollination, adjustment of sowing dates.
