研究了6种大豆种衣剂对“皖豆13号”新、陈种子萌发及活力的影响，结果表明；包衣处理具有较好的防霉效果，对新种子萌发与活力无显著影响。20％、25％和30％大豆种衣剂对陈种子萌发与活力无显著影响；1号、2号和4号大豆种衣剂则能显著地提高陈种子发芽率与活力。包衣新种子常规贮藏一年，发芽率下降44．3％～46．3％，活力指数下降63．6％～79．2％，不宜再做种用。 The effects of six kinds of soybean seed coating agents on germination and vigor of new and old seeds of “Wan Dou 13” were studied. The results showed that the coating treatment had good anti-mildew effect and had no significant effect on germination and vigor of new seeds. No significant effects of 20%, 25% and 30% soybean seed coating agent on seed germination and vigor of Chen seeds were observed. No seed treatment of soybean seed coating no. 1, 2 and 4 could significantly improve seed germination rate and vigor of Chen seeds. Conventional storage of new seeds for one year, the germination rate decreased 44.3% ~ 46.3%, vitality index decreased 63.6% ~ 79.2%, should not be used as seed.
