摘　　要：试验表明,壮丰安处理小麦种子,以150mg/L,4～6h 浸种或以3mL/10kg 种子的剂量拌种为宜,此浓度不影响种子发芽,对冬小麦冬前叶片、分蘖、根系均有良好影响。明显缩短叶鞘及叶片长度,促进叶片和分蘖分化,增加单株叶面积、叶片叶绿素含量、根系总量及活力、植株地上、地下干重、根冠比;植株对环境条件的反应敏感性增加,提高植株抗逆潜力的发挥,对培养冬前壮苗、保障安全越冬有良好的调节作用。The studies of Zhuangfengan treatment on wheat seeds showed that the suitable content is 150 mL/L,4-6 hour(seed water-soaking).Seed treatment with Zhuangfengan at this content has beneficial effect on the growth and development of leaves,tillers and roots of the wheat seedling before overwintering.It can increase significanlly the chlorophyll content,root vigor,seedling dry weight and root-shoot ratio.The results also showed that seed treatment with suitable concentration of Zhuangfengan can activate the potential of stress tolerlance,so that to guarantee a safe over-wintering.
