由于种子在储藏期间易受虫霉、鼠雀、混杂以及各种事故的危害,从而丧失发芽率,失去种用价值。因此,搞好“五无”对保证种子安全储藏,降低种子损耗,节省费用开支,提高仓储的技术水平和管理水平具有重大意义。一、确定标准形成制度无虫害:所保管的种子,没有检疫性仓虫,每个仓房、垛堆及包装物与器材没有感染活虫,或个别仓房、包装物和器材发现微量活虫,虫口密度不超过2头,且能及时杀灭处理没有造成扩散和损失的均算无虫。入库时种子感染活虫,能够及时检出隔离存放,在半个月内处理达到无虫标准的,也算无虫。无霉变:所保管的种子无霉坏
Due to the seeds during the storage of insecticides susceptible, rat warbler, mixed with a variety of accidents, thus losing the germination rate, loss of species value. Therefore, improving the “five no ” is of great significance to ensure the safe storage of seeds, reduce seed losses, save costs and improve the technical level and management of storage. First, to determine the standard formation system Insect pests: the custody of the seeds, there is no quarantine warehouse worms, each warehouse, stacks and packaging materials and equipment are not infected live insects, or individual barns, packaging and equipment found traces of live insects, insects mouth Density of not more than 2, and can promptly kill the treatment did not cause proliferation and loss are not insects. Seeds infected live insects stored, can be promptly isolated and stored, in half a month to deal with no worm standard, can be considered no worms. No mildew: the custody of seeds without moldy
