水培茶苗结果表明，锌、钼在０．０２～０．５０ｇｇ－１范围可提高茶苗根系硝酸还原酶活性（ＮＲＡ），其主要取决于生长介质中Ｍｏ的浓度，但Ｍｏ－Ｚｎ间适度的含量比及一定范围的Ｚｎ含量有利于ＮＲＡ的提高；Ｚｎ、Ｍｏ增加茶苗春梢、夏稍全氮量和蛋白质含量，也促进氨基酸代谢；Ｚｎ、Ｍｏ对秋季茶苗体内全氮量无明显效应，但有利于根中氨基酸代谢．
The results of hydroponics from tea plantation showed that the nitrate reductase activity (NRA) of tea seedling roots could be increased by zinc and molybdenum in the range of 0.02-0.50gg-1, which mainly depended on the concentration of Mo in the growth medium. However, Appropriate content ratio and a certain range of Zn content is conducive to the improvement of NRA; Zn, Mo increased tea shoot spring, summer slightly total nitrogen and protein content, but also promote amino acid metabolism; Zn, Mo autumn tea seedlings in vivo total nitrogen No obvious effect, but beneficial to root amino acid metabolism.
