The results showed that banana trees, which were planted in plantation with appropriate available phosphorus soil, fertilized by 0.87kg urea, 1.335kg KCl, 2.0kg organic fertilizer, 125.0g magnesium sulfate per plant, sprayed by 0.2% borax solution one time, especially fertilized by 1.165kg calcium superphosphate per plant and N ∶P O ∶K O = 1.0 ∶0.35 ∶2.0, grew fine.
