摘　　要：2003—2006年,对壳聚糖包衣大白菜种子的出苗率进行研究,结果表明,20 g种子用10.2 mg的0.177 mm食品级壳聚糖包衣太原二青B,C粒径等级种子,或用3.4～10.2 mg的0.177 mm食品级壳聚糖包衣晋菜三号B,C粒径等级种子,出土幼苗生长正常,无药害,并可提高种子的抗逆性和耐贮性,增加出苗数,可用铝箔袋或纸袋贮存1～2 a。0.177 mm食品级壳聚糖包衣20 g太原二青和晋菜三号的B粒径等级种子的用量增加到15～30 mg时,其幼苗生长正常无药害,但出苗率不能明显提高。The result of two to three years experiments showed： when B or C class seeds of Taiyuan Erqing coated with food level 0.177 mm Chitosan of 10.2 mg/20 g seed,or B or C class seeds of Jincai 3 coated with 0.177 mm Chitosan of food level of 3.4～10.2 mg/20 g seed,seedling appeared normal growth and phytotoxicity.Stress and storage resistance of seed,seedling rate also increased,and seeds with aluminum foil or paper bag could be kept in storage above one to two years.When seeding rates of Taiyuan Erqing coated with 0.177 mm chitosan of food level and B class Jincai 3 increased,15～30 mg/20 g,the seedling appeared normal growth and phytotoxicity,but germination rate no significantly improved.
