玉米种子贮藏过程中比较容易出现低温冻害和发热霉变,尤其夏季温度高、湿度大,种子呼吸旺盛,不仅会造成种子养分的消耗,而且还可能会导致种子堆发热霉变,从而降低种子活力,甚至丧失生活力,因此,玉米种子夏季贮藏需要特别重视。 In the process of storage of corn seeds, cold frost damage and moldy mildew are more likely to occur, especially in summer when the temperature is high, the humidity is high, and the seeds are well rested, which not only causes the consumption of seed nutrients but also may cause the pile of seeds to become hot and mildew, thereby reducing the seed vigor , Or even lose their viability. Therefore, the summer storage of corn seeds needs special attention.
