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.
