| 摘 要： | 应用酒泉、张掖、武威实况资料,从作物的各个生长发育期进行了对比分析,结果表明强冷空气爆发是造成冻害的直接原因,前期气温异常偏高使农作物生育期提前、气温和地温较低加剧了冻害程度。并提出了防御冻害发生的有效措施。

| Abstract: | Using the real-time data of frost at Jiuquan, ZhangYe and WuWei observation stations, analyzed contrastively the cause and the disaster of strong frost in various growth period of crops. It shows that outbreak of strong cold air is the direct cause of frost disasters, anomalous rise of temperature causing the crops to grow ahead of schedule, and lower air and ground temperature worsen the frost disasters. At last, effective prevention countermeasures are set up. |
