The dosage depends on the variety, the size of the crown, the amount of fruit in the current year and the strength of the tree. Under the condition, 10 kilograms of charred mud ash is applied to each plant. At the same time, extra-root topdressing before defoliation can prolong the life of leaves and improve the quality of flower buds. 2.
