我国北方冬季寒冷而且漫长,为不使冬贮种子发生冻害、霉变、虫害、鼠害、雀害等,必须对贮藏的种子进行科学管理,掌握安全的贮藏技术,使其安全越冬,保证农业生产用种。 1.确保入库种子均达到安全含水量。种子贮藏效果的好坏,很大部分取决于种子含水量,种子含水量的高低是影响种子寿命的主要因素。种子冬贮前必须充分干燥,降到安全水分可入库。禾谷类作物种子安全含水量为12～15%;油料作物种子的安全含水量为8～10%;薯类种子含水量为65～80%,在冬贮过程中,水
Cold and long winter in northern China, in order not to freeze the winter seed storage, mildew, pests, rodents, etc., the storage of seeds must be scientifically managed to master the safe storage technology to make it safe and winter, to ensure that agriculture Production of species. 1. Make sure that all incoming seeds reach safe water content. Seed storage effect is good or bad, largely depends on the seed water content, seed moisture content is the main factor affecting seed life. Seed must be fully dried before winter storage, down to safe water can be stored. The safe moisture content of cereals is 12-15%; the safe water content of oil seeds is 8-10%; the content of potato seeds is 65-80%
