| 摘 要： | 通过盆栽试验,研究了不同浓度牛蒡提取液对菠菜生长及品质的影响.结果表明,与清水对照相比,喷施30～1500 mg/L牛蒡提取液可使菠菜鲜重增加10.8%～30.0%;可能由于"稀释效应",叶绿素含量降低2.7%～15.7%;Vc含量提高46.1%～136.4%;硝酸盐含量降低 23.2%～69.2%;草酸含量降低 22.3% ～67.6%.其中,对叶绿素含量、Vc 含量、硝酸盐及草酸含量的效应,都以 30 mg/L 处理的效果最好.而鲜重方面,30 mg/L处理与效果最好的 500 mg/L处理之间差异亦不显著.因此,从对菠菜的生长情况、品质情况及经济角度综合考虑,牛蒡提取液应用在菠菜上的适宜浓度为 30 mg/L.

| Abstract: | The effects of different concentrations of Arctium lappa L.extract on spinach's growth and quality were studied by pot experiment.The results showed that the fresh weight of spinach increased by 10.8% - 30.0% after spraying Arctium lappa L.extract which concentrations ranged from 30 mg/L to 1500 mg/L,the content of chlorophyll decreased by 2.7% - 15.7% which may be attributed to the dilution effect,the content of Vc increased by 46.1% - 136.4%,the content of nitrate decreased by 23.2% - 69.2%,the content of... |
