| 摘 要： | 硅素是一种可以改善农作物品质的有益元素。通过盆栽试验研究硅肥的两种施用方法(土壤施用和叶面喷施)及其不同施用量对川西蒙山茶叶品质的影响。结果表明:施用硅肥对茶叶品质具有显著影响,土壤施硅可使茶叶中氨基酸和可溶性糖含量比对照分别提高38.66%和16.98%,而茶多酚和咖啡碱的含量分别降低15.28%和20.24%;叶面施硅则可使氨基酸和咖啡碱含量比对照分别提高33.47%和28.96%,而茶多酚和可溶性糖含量则分别降低12.39%和13.29%。

| Abstract: | Silicon is a beneficial element that can improve the quality of the crops. Effects of different ways (applying silicon to soil and spraying to foliage)of silicon treatment and its rate on quality of Mengshan tea were studied with the tea cultured in pots. Experiment results showed that silicon applying has a significant effect to the quality of tea; when applying silicon in soil, the content of amino acid and soluble sugar in tea increased 38.66% and 16.98% respectively compared with the CK. But the content of tea polyphenol and caffeine decreased 15.28% and 20.24% respectively, when spraying silicon on foliage, the content of amino acid and caffeine increased 33.47% and 28.96% respectively compared with the CK. The content of tea polyphenol and soluble sugar decreased 12.39% and 13.29% respectively. |
