| 摘 要： | 1980年以来,晋南地区年平均气温开始快速上升,平均每年上升约0.1℃。进入90年代后,持续高温灾害天气的频繁出现,对农作物的生长发育和产量均造成了不同程度的影响。通过气象分析和跟踪研究证明,日最高气温在35℃以上的灾害天气持续8d以上时,大多数农作物的花粉开始败育,导致结实不良,产量降低。

| Abstract: | Since 1980,the temperature in South Shanxi Province has obviously gone up ,average rising about 0.1 ℃/year. Since 1990,continuous high temperature days have frequently occurred which appeared damage to the growth and yield of crops to various degree.In this paper, the meteorological phenomenon data were analyzed and studied purposely. The result indicated, once diurnal maximum temperature reached over 35℃,the pollen formation of crops began to be affected negatively. When diurnal maximum temperature over 35℃ lasted for over 8d, most of crops' pollen aborted, resulting in bad seed-setting and low yield. |
