【Abstract】 Recovery effect of organic foliar fertilizers, Kelpak, Shimalv and solutions in combination with 0.5% urea and 0.3% potassium dihydrogen phosphate, on tea freeze injury was investigated. Results indicated that all these fertilizers could promote the recovery growth of frozen tea buds and leaves, and among them, Kelpak and Shimalv showed better effect after two applications. Consequently, Kelpak and Shimalv could be appropriately applied in the recovery of tea freeze injury, and thus extensively and intensively applied in vast tea plantations.更多还原
