冬季,各种农作物种子陆续入库,如何贮藏好使其安全越冬,是一项很重要的工作。如果入库种子水分高,遇低温就会受到冻害;温度高时,又要发生霉变,这都会使种子失去生命力。同时,在贮藏期间由于受到条件的限制还会发生虫害、鼠害、雀害等。所以,必须对冬贮种子进行科学管理,掌握安全贮藏技术,使种子安全越冬,保证农业生产用种。 1.种子贮藏温度种子在冬贮过程中,需经常对种堆的温度进行检查。因为种子遇低温则受冻害,一般情况下,水分在15%以下的种子,温度保持在-20～-30℃和40℃之间,其生命力均不受影响,如温度过低或过高,应随时调节库房的通风设施,保证种子处于安全状态。
In winter, various kinds of crop seeds are gradually put into storage, and how to store them so that they can be safe for winter will be an important task. If the storage of high moisture seeds, in case of low temperature will be frost damage; temperature is high, but also mildew, which will make the seeds lose their vitality. At the same time, pests, rodents, birdwatching and the like also occur during storage due to the restriction of conditions. Therefore, it is necessary to carry out scientific management of winter storage seeds, master the safe storage technology, make the seeds safe and wintering, and ensure that agricultural production is used for planting. 1. Seed storage temperature seeds in winter storage process, often need to check the temperature of the seed pile. Because the seed in the case of low temperature by the frost damage, under normal circumstances, the water content below 15% of the seeds, the temperature maintained at -20 ~ -30 ℃ and 40 ℃, its vitality are not affected, such as the temperature is too low or too high, The ventilation of the warehouse should be adjusted at any time to ensure that the seeds are in a safe condition.
