Abstract: Field experiments were conducted to study the effects of extra root topdressing different liquid fertilizers of newly-built tea plantations. The results showed that extra root topdressing different liquid fertilizers could increase the survival rate of tea seedlings after transplanting, and the survival rate could reach 95.71%-98.57%. In one year, tea seedlings could reach plant height of 30 cm, stem diameter of 5-6 mm, 3-4 new branch, branch length of 20 cm, tree width of 25-30 cm, and root length of 8 cm. The effect of sealing small rows in the tea garden could be realized within a year.

Key words: newly-built tea plantation, extra root topdressing, liquid fertilizer, garden sealing
