我国北方冬季漫长,气候寒冷,玉米收获时天气已经转冷,由于果穗外有苞叶,在植株上得不到充分干燥,所以玉米原始水分一般较高。根据研究结果与实践经验,玉米水分高于17%时,易受冻害,发芽率迅速降低,此时玉米种子贮藏措施不利,极易发生低温冻害等情况,因而采取有效的方法科学贮藏,以保证玉米种子安全过冬,显得尤为重要。1贮藏前的准备工作 The long winter in northern China, the climate is cold, the weather has been cold when corn harvest, due to the outer ear bracts leaves, not fully dried in the plant, so the higher the original corn water. According to the research results and practical experience, when corn moisture is higher than 17%, it is easy to suffer frost damage and the germination rate is rapidly reduced. At this time, corn seed storage measures are unfavorable and low temperature frost damage easily occurs. Therefore, effective methods are adopted for scientific storage It is especially important that the corn seed is safe for winter. 1 preparation before storage
