Abstract: The results in field experiment showed that, under the soil fertility condition in banana garden in Zhangzhou area, the optimum fertilizer application was N675 kg·hm-2, P2O5 60—120 kg·hm-2, K2O 900～1200 kg·hm-2, the optimum ratio of N: P2O5: K2O was 1:0.1—0.2:1.3—1.8 in order to gain the banana yield about 45t·hm-2.In the sandy soil, the optimum S and Mg fertilizers were 90kg·hm-2 and MgCO3 75kg·hm-2 respectively, To compare with traditional fertilization, the balanced fertilization increased banana yield by 7.8%.Soluble matters, reductive sugar content and total sugar content were increased remarkably after increasing application of P, K fertilizer.Vc and reductive sugar content were also increased significantly after applied S fertilizer.Balanced fertilization increased soluble matters by 6.9%, Vc by 9.0%, reductive sugar content by 22.8%compared to traditional fertilization.
