本文研究了种衣剂24号包衣棉种在三种不同材质包装袋中的贮存时间与种子发芽率的关系。结果表明．在自然条件下包衣棉种贮存于普通牛皮纸袋、塑料自封袋以及普通牛皮纸袋和塑料自封袋双层袋中14个月．发芽率均有所下降．其中选用牛皮纸袋包装的棉种发芽率下降达10个百分点，不能实现隔年安全存放，另外两种包装可以隔年安全存放；但同一包装材料包衣棉种与未包衣棉种的发芽率没有统计水平上的差异。
In this paper, we studied the relationship between the storage time and the seed germination rate of seed coating 24 # cotton seed in three different kinds of bags. The results show. Under natural conditions, the cotton seed coat is stored for 14 months in ordinary kraft paper bags, plastic self-sealing bags, double kraft bags and plastic self-sealing bags. Germination rates have declined. The selection of kraft paper bags of cotton seed germination rate decreased by 10 percentage points, can not be safely stored every other year, the other two kinds of packaging can be safely stored next year; but the same packaging materials, coated and uncoated cotton germination rate is not statistically The difference in level.
