摘　　要：试验以温麦8号为研究对象,采用土培法研究复合食品防腐剂(苯甲酸钠和山梨酸钾)对小麦种子萌发和幼苗生长的影响。结果表明,低浓度(2 g/L)的复合食品防腐剂对小麦种子萌发无显著效果,但明显促进幼苗生长;高浓度(≥4 g/L)的复合食品防腐剂对小麦种子的萌发和幼苗生长均表现出抑制作用。Using the soil culture method,the influence of composite food preservative(formed by sodium benzoate and potassium sorbate) on the morphological indexes and physiological indexes of wheat,Wenmai 8 was studied.The results showed that low concentration of preservatives(2 g / L) had no significant influence on the wheat seed germination,but could promote the seedling growth of wheat.While,high concentration of compound preservatives(≥4 g / L) had obvious inhibition on the seed germination and seedling growth.
