摘　　要：适宜浓度的聚乙二醇和甲基托布津能明显提高菠菜陈种子发芽率、幼苗根系活力、叶片叶绿素含量及田间成苗率。其中单独处理时,100 mg/L聚乙二醇,2.0 g/L甲基托布津对种子发芽率、幼苗根系活力、叶片叶绿素含量和田间成苗率效果最好;二者复配处理时,100 mg/L聚乙二醇+2.0 g/L甲基托布津对提高种子发芽率、根系活力、叶绿素含量以及田间成苗效果最好,与CK差异达到显著水平。The proper concentration of thiophanate-methyl and PEG could increase germination rate,chlorophyll content of leaves,seedling root activity and field emergence rate of aged spinach seeds.The results showed that the treatments PEG 100 mg/L,thiophanate-methyl 2.0 g/L and PEG 100 mg/L ＋ thiophanate-methyl 2.0 g/L were optimum respectively for increasing the germination rate,chlorophyll content of leaves,seedling root activity and field emergence rate,and the mixed treatment had significant difference with the control.
