Effects of Slow-release Fertilizer on Growth,Yield and Quality of Banana
In order to study the effects of slow-release fertilizer on the growth,yield and quality of banana,four treatments of conventional fertilization,slow-release fertilizer stick,20％reduced slow-release fertilizer stick(80％slow-release fertilizer stick)and control(no fertilization)were set up to compare and analyze the plant height,stem circumference,leaf number,nutrient accumulation,yield and quality indexes of banana.The results showed that compared with conventional fertilization,the number of leaves of banana treated with slow-release fertilizer stick increased significantly by 6.55％,the nitrogen accumulation increased by 2.36％,and the accumulation of phosphorus and potassium in 80％slow-release fertilizer stick treatment was signifi-cantly increased by 14.13％and 24.40％,also slow-release fertilizer stick treatment could significantly in-crease yield of single plant by 16.90％-17.63％and edible rate by 6.46％-10.06％,but had no significant effect on soluble solids,titratable acid and vitamin C content of banana.Overall consideration of above results,20％reduction of slow-release fertilizer stick was the optimal fertilization treatment under the test conditions.
