摘　　要：研究了不同浓度寡聚酸钾对豌豆幼苗生长、根系活力和光合色素含量的影响。结果表明．0.1-10mg／kg的寡聚酸钾均能显著促进豌豆幼苗的生长，提高根系活力和光合色素的含量。1mg／kg的寡聚酸钾对豌豆幼苗根系活力、光合色素含量以及生长指标的促进作用最为明显。The effects of different levels of potassium glucose oligosaccharide acids on the growth and some physiological characteristics of garden pea were studied. The results showed that under 0. 1mg/kg to 10mg/kg potassium glucose oligosaccharide acid levels,the leaf numbers, stem length, root length,the top fresh weight and root fresh weight increased obviously; At the same time,the root activity and the photosynthetic pigments were significantly higher than that of control. The effect of lmg/kg potassium glucose oligosaccharide acid level on the growth of garden pea is the best.
