摘要
以黄瓜"津优33号"品种为试材,研究1 500 mg/L浓度的KHCO3和不同浓度NaH-SO3复合对设施黄瓜幼苗生长的影响,探讨促进黄瓜幼苗生产的最佳组合。结果表明:KHCO3和NaHSO3复合配比可提高设施黄瓜幼苗光合速率,进而提高幼苗的根系数、根冠比、植株干重和鲜重比值等指标,培育壮苗。与对照相比,1 500 mg/L KHCO3+200 mg/L NaHSO3处理使黄瓜的茎粗、根系数、光合速率、根冠比、植株干重和鲜重比值分别提高了10.19%、42.86%、62.89%、46.15%、39.60%,效果较为显著。
Taking ＂Jinyou No.33＂ cucumber as test material,the effect of 1 500 mg/L KHCO3 and different concentration NaHSO3 combined treatment on the affection of seedlings of cucumber growth in greenhouse were studied.The best combination to promote seedlings of cucumber growth was discused.The results showed that treatments of KHCO3 and NaHSO3 combined improved photosynthetic rate,shoot ratio,root factor,and ratio of dry and fresh weight.The treatment of 1 500 mg/L KHCO3＋200 mg/L NaHSO3 had an obvious effect on the cucumber for diameter,photosynthetic rate,shoot ratio,root factor,ratio of dry and fresh weight.,which increased 110.0%,14.7%,57.9%,38.5%and 15.5%compared with the contrast.
