一九七三年入夏以来,长期阴雨,是历史上罕见的冷夏。我区早稻早熟品种,在幼穗发育和抽穗开花时期遭受冷害,损失严重。查明冷害发生的原因,提出防止冷害的措施,对于更好地落实毛主席“备战、备荒、为人民”和“广积粮”的指示,具有极其重要的意义。 Long-term overcast and rainy weather since its introduction in summer 1973 is a rare cold summer in history. Early precocious varieties of early rice in our district suffered chilling damage and severe loss during the development and flowering of young spikes. Identifying the causes of cold damage and putting forward measures to prevent cold damage have extremely important significance for the better implementation of Chairman Mao’s directives of “preparing for war, preparing for shortage, benefiting the people” and “expanding grain ration.”
