摘要
通过水培方法 ,就环境中铝离子对茶幼苗生长影响进行初步研究 .结果表明 :适当浓度的铝离子浓度有利于茶幼苗的生长 ,当铝离子浓度超过 1 0 mgL- 1 时 ,则使茶幼苗受害 ,铝离子对茶幼苗毒害主要表现在对根生长的抑制作用 。
The effects of ionic aluminum in the environment to the growth of tea seedlings were studied under the condition of solution culture. The results indicated that moderate concentration of ionic aluminum was beneficial to the growth of tea seedlings ,but it would have toxic effects if the concentration of ionic aluminum exceeded 10mg L -1 . The toxic symptoms were primarily the inhibition to the root growth and had some harmful effects to the growth of stems and leaves.
