A Preliminary Study on the Development of An Organic and Mineral Mixed Fertilizer Applied in Banana

According to the Banana growth regulation,the need of its nutrient and the soil agro-chemical condit ions in Fujian Province,on organic and mineral mixed fertilizer applied in Banana was exploited and studied.The experimental results showed that under the condition of equal ni-trogen amount,Banana comprehensive character of this fertiliter treatment was superior to those of the control.Its yield increased by 14.0%～31.9%。Banana bunchy top incidence decreased by 7.9%as compared with the control.The differences among treatment were significant.The changes of pH value,organic matter NPK content and microbe population of soil were also investi-galed in the experiment.after the organic and mineral mixed fertilizer treatment.The results showed that this fertilizer had a high and long effectiveness and could increase the fertility of soil.In the past two years,we tried to adapt the development of new product to the need Of mar-ket,the organic and mineral mixed fertilizer was produced more than 300 ton.Its application had gained significant economic efficiency.
