为了明确河北滨海平原区冬小麦的主要隐性灾害,通过对河北滨海平原区冬小麦隐性灾害发生情况的调查,研究了该地区在1996—2011年小麦的主要隐性灾害,包括冷害、冻害、干旱危害、干热风危害、盐碱危害等危害,并提出了防控措施。结果表明,在河北滨海平原区小麦生育期间的降水量为138.32 mm,季节性干旱以重旱为主;近几年干热风危害有减轻的趋势。为指导滨海平原区小麦生产提供理论依据。
In order to clarify the major hidden hazards of winter wheat in the coastal plain of Hebei Province, the main hidden hazards of wheat in the region from 1996 to 2011 were investigated, including cold damage, frost damage and drought Harm, hot and dry wind hazards, salt hazards and other hazards, and put forward prevention and control measures. The results showed that during the growth of wheat in the coastal plains of Hebei, the precipitation was 138.32 mm and the seasonal drought was dominated by heavy drought. In recent years, the harm of dry-hot wind has tended to decrease. Provide a theoretical basis for guiding the wheat production in the coastal plain area.
