| 摘要: |
| 文章以土壤栽培为对照，采用1/2日本园试营养液配方研究气雾栽培对车前生长、产量和品质的影响，探索适合药用植物车前高效种植的新途径。结果表明，和土培组相比，雾培组车前生长周期缩短82 d；株高、叶面积、根系体积、干重显著增加，分别提高了10.4%，148.3%，218.0%，250.3%；植株可溶性蛋白质、Vc含量、可溶性糖含量均高于土培组，分别是土培组的1.07，1.41，1.31倍；总黄酮、多糖和大车前苷含量均低于土培组，但仍达到药用质量标准。雾培有利于车前的生长，可缩短生长周期，提高生物量，改善营养品质，但不利于药用成分的积累。 |

| Abstract: |
| The growth and quality of medicinal herb Plantago asiatica in aeroponics (soil as the control) were studied. The results showed that the growth rate of P. asiatica in areroponics was superior than that in soil, the growth period was shorted by 82 days than the control. And plant height, leaf area, root volume and dry weight significently increased by 10.4%, 148.3%, 218.0% and 250.3% respectively. The contents of vitamin C, soluble protein and soluble sugar of P. asiatica in aeroponics were 1.07, 1.41 and 1.31 times as the control. However, there were reduction in the contents of total flavonoids, polysaccharides and plantamajoside compared with soil culture. The results suggested that aeroponics system could be an alternative production system for medicinal plant, which could shorten the growth period, improve yield and edible nutrition quality, but the contents of medicinal composition decreased . |
