干热风是危害小麦的农业气象灾害。亚、欧、中东、北非、苏联以及我国北方麦区,小麦抽穗至成熟期间经常遭受干热风,一般减产5～10％,重灾减产20％以上。近年来农学、气象、生理等各学科对小麦干热风的研究日趋深广,已基本阐明小麦干热风发生的气候规律、危害小麦的生理机制等,并在此基础上提出了综合防御措施以及今后待研究的一些问题。
Dry hot winds are agrometeorological hazards that endanger wheat. Asia, Europe, the Middle East, North Africa, the Soviet Union and northern China. Wheat is often exposed to dry and hot wind from heading to maturity, generally cutting 5 to 10 percent and harming more than 20 percent. In recent years, agronomy, meteorology, physiology and other disciplines on wheat dry and hot wind increasingly extensive research has basically clarified the dry and hot wheat wind and the occurrence of the laws of the physiological mechanisms of wheat and other hazards, and on this basis, put forward a comprehensive defensive measures and the future to be Some questions to study.
