摘要: 通过大田试验,研究新建茶园根外追施不同液态肥的效果。结果表明,不同液态肥根外追施均能提高茶苗移栽成活率,成活率达到95.71%~98.57%。1年内茶苗可达到株高30 cm、茎粗5~6 mm、新分枝3~4个、分枝长20 cm、树幅25~30 cm、根长8 cm,实现1年内茶园封小行的效果。

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
