摘    要:通过盆栽试验,研究了牛蒡粗提液、牛蒡寡糖两种牛蒡提取物对菠菜生长及品质的影响。结果表明,喷施牛蒡粗提液和牛蒡寡糖均可增加菠菜鲜重,分别比清水处理的高38.3%、24.7%;同时,提高菠菜Vc、总糖含量,降低菠菜体内硝酸盐、草酸含量。说明牛蒡粗提液和牛蒡寡糖不仅能促进菠菜生长,而且能改善菠菜品质。牛蒡粗提液和牛蒡寡糖相比,牛蒡粗提液的效果优于牛蒡寡糖,而且牛蒡粗提液的成本约为牛蒡寡糖的1/10~1/15。因此,从使用效果及经济效益考虑,牛蒡粗提液的应用前景更佳。

关 键 词:牛蒡粗提液    牛蒡寡糖    菠菜    品质

Abstract:The effects of burdock (Arctium lappa L.) extracts on spinach's growth and quality were studied by using pot experiment. The results show that fresh weight is increased by 38.3% and 24.7% respectively compared to that of CK treatment after spraying the burdock crude extract or burdock oligosaccharide, while, contents of Vc and total sugar of spinach are increased ,contents of nitrate and oxalate are decreased. Therefore, the burdock crude extract or burdock oligosaccharide could improve spinach's growth and quality. The effects of the burdock crude extract on spinach's growth and quality are better than those of burdock oligosaccharide. In addition, cost of the burdock crude extract is about 1/10-1/15 of that of burdock oligosaccharide. The prospect of the burdock crude extract application in agriculture is better than that of burdock oligosaccharide.
Keywords:burdock crude extract  burdock oligosaccharide  spinach  quality
