摘　　要：为探究不同质量浓度海带多糖对两种水稻(津川一号和天隆优619)幼苗生长和生理指标的影响,旨在确定海带多糖对水稻幼苗的作用效果,并筛选出适宜的海带多糖质量浓度以促进水稻的健康生长。试验采用水培法,设置了5个不同浓度海带多糖处理组和一个对照组。结果表明,海带多糖对水稻幼苗的苗长、根长、鲜重、干重、抗氧化酶活性、丙二醛含量和光合色素含量均有一定影响,且最佳质量浓度为0.15 g/L。In order to investigate the effects of different mass concentrations of kelp polysaccharide on the growth and physiological indexes of two kinds of rice seedlings (Jinchuan No.1 and Tianlongyou 619), the aim was to determine the effect of kelp polysaccharide on rice seedlings and to screen out the appropriate mass concentration of kelp polysaccharide to promote the healthy growth of rice. The experiment was conducted by hydroponics, and five treatment groups with different concentrations of kelp polysaccharide and one control group were set up. The results showed that kelp polysaccharide had a certain effect on seedling length, root length, fresh weight, dry weight, antioxidant enzyme activity, malondialdehyde content and photosynthetic pigment content of rice seedlings, and the optimal quality concentration was 0.15 g/L.
