低温冷害是一种严重的气象灾害。解放以来,我省遇到八次低温冷害,占灾害年的40%。今年4～5月由于低温寡照,旱田作物出苗拖后7～10天,苗小、苗弱,生长迟缓,水稻秧苗少1～1.5片叶,春季冷害已经形成。根据气象部门预报,今年是低温年,因此要千方百计地采取一切有效措施,加强田间管理,把作物被耽误的生长撵上来,促进早熟,夺取丰收。根据各地经验,提出以下几项抗御低温冷害的措施。
Cold damage is a serious weather disaster. Since the liberation, our province has encountered eight cold chills, accounting for 40% of the disaster year. April to May this year, due to low temperature, according to field, dry crop emergence of seedlings delayed 7 to 10 days, seedling, weak seedlings, growth retardation, rice seedlings less 1 to 1.5 leaves, chilling injury has been formed in the spring. According to the forecasters of the meteorological department, this year is a year of low temperature. Therefore, we must do everything possible to take effective measures to strengthen field management, increase the delayed growth of crops, and promote premature harvest and harvest. According to local experience, put forward the following countermeasures against chilling injury.
