有机叶面肥对茶树冻害的恢复效果

Recovery Effect of Organic Foliar Fertilizer on Tea Freeze Injury

试验研究了有机叶面肥凯普克、狮马绿以及0.5%尿素加0.3%磷酸二氢钾混合液对茶树冻害的恢复效果。结果表明,喷施凯普克、狮马绿以及0.5%尿素加0.3%磷酸二氢钾混合液叶面肥均能促进冻后茶树芽叶的恢复生长,其中以凯普克和狮马绿混合液喷施2次的效果最佳,其适宜作为茶树冻害护理和复壮措施在广大茶园推广应用。

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.
