由于长期寒冷潮湿的天气带来疾病风险,孟加拉国的寒浪威胁到冬季作物,特别是土豆。 A cold wave in Bangladesh threatens winter crops, especially potatoes, due to disease risks from prolonged cool, damp weather.

孟加拉国17个区的寒浪引发了对农业的关注,尤其是对于诸如土豆、洋葱、番茄和稻苗等冬季作物而言,由于长期凉爽,潮湿条件增加了疾病风险,如晚发芽、粉状温和小菜。 A cold wave across 17 districts in Bangladesh has raised agricultural concerns, particularly for winter crops like potatoes, onions, tomatoes, and rice seedlings, due to prolonged cool, damp conditions increasing disease risks such as late blight, powdery mildew, and tipburn. 专家警告说,温度低于13摄氏度和高湿度的疾病会蔓延,土豆最容易受到感染。 Experts warn that temperatures below 13°C and high humidity favor disease spread, with potatoes most vulnerable. 建议农民每七天使用杀真菌剂,并监测夜间温度。 Farmers are advised to apply fungicides every seven days and monitor nighttime temperatures. 虽然种子床的稻苗基本上仍因宿舍闭塞而不受影响,但长期寒冷可能延缓生长。 While rice seedlings in seedbeds remain largely unaffected due to dormancy, prolonged cold could delay growth. 迄今为止,没有重大产量损失的报告,但如果条件持续下去或作物被移植,风险就会增加。 No significant yield losses have been reported so far, but risks rise if conditions persist or crops are transplanted.
