摘　　要：本试验以几种不同浓度的矮壮素溶液（200 mg/L、300 mg/L、400 mg/L、500 mg/L、600 mg/L）对播种前黄瓜基质进行底水浇灌处理,研究不同浓度处理的矮壮素对穴盘黄瓜幼苗质量的影响。研究结果表明：播种前以400 mg/L的矮壮素溶液进行底水浇灌处理的黄瓜幼苗的株高、下胚轴长度、茎粗、根系活力、叶绿素总含量等表现最佳,300mg/L效果次之。由此可以得出结论：基质浇灌300~400 mg/L的矮壮素溶液可以控制黄瓜幼苗徒长,有助于培育壮苗。This experiment was conducted by drenching the substrate with varied concentrations of ehlormequat chloride （200mg/L, 300rag/L, 400mg/L, 500mg/L and 600mg/L） before sowing to study their effects on the quality of cucumber plug seedlings. The results demonstrated that the cucumber seedlings treated with 400 mg/L chlormequat chloride showed good results in terms of the plant height, hypocotyl length, stem diameter, root vigor, chlorophyll content and soluble sugar content of cucumber seedlings, which were better than seedlings treated with 300 mg/L ehlormequat chloride. It could therefore be concluded that drenching the substrate with 300 - 400 mg/L chlormequat chloride could help avoid excessive seedling growth and cultivate strong seedlings.
