摘　　要：2003—2005年通过用3种规格的壳聚糖分别包衣大白菜种子进行试验,结果表明,当年包衣种子的幼苗生长正常,无药害,出苗率提高。但结合壳聚糖用量与出苗率之间的关系及包衣种子贮存1～2 a后的出苗率,不宜用工业级壳聚糖包衣大白菜种子;若用铝箔袋贮存包衣种子1 a以上,也不宜用0.149 mm食品级壳聚糖,20 g种子用3.4～13.6 mg的0.177 mm食品级壳聚糖包衣较适用,能提高种子的抗逆性和耐贮性。Three-year experiment of Chinese cabbage seeds with three specifications of chitosan coating showed： seed with chitosan coating in those years had normal growth,phytotoxicity and increased seedling rate.But considering the relationship of chitosan dosage with seedling rate,seedling rate of the coated seed in 1～2 storage years,no using of industrial chitosan coating was suggested.When coated seed with aluminum foil bag was kept in storage over 1 year,it was better not to be kept with 0.149 mm chitosan of food level;while available 3.4～13.6 mg/20 g seed of 0.177 mm chitosan of food level could improve stress and storage resistance of seed.
