摘要
在丘陵茶树上应用亚硫酸氢钠 ,能提高光合速率和叶绿素含量 ,增加一芽一叶、一芽二叶和一芽三叶的干物质积累 ,以及茶叶内水浸出物、氨基酸、茶多酚等主要成分的含量 ,从而获得茶叶增产 ,提高品质的作用。研究指出 :亚硫酸氢钠提高光合速率与降低硝酸还原酶活性有关。
Sprayed 200mg/L NaHSO 3 upon tea trees in hill area,it was shown that NaHSO 3 could obviously raise photosynthetic rate and chlorophyll content, increase dry matter accumulation rate in one bud with one leaf, two leaves,or three leaves,and raise main composition content of water extract,amino acid, and tea ployphendes of tea leaf.Therefore,yield and quality of hill tea was raised by NaHSO 3. And increase of photosynthetic rate by NaHSO 3 is related to decrease of nitratereductase activity.
