摘要:
本文根据香蕉生长规律及其所需的营养比例,结合我省土壤状况而进行了香蕉专用有机无机复肥的开发研究,结果已研制出一种适宜香蕉生长的专用肥配方。经两年来的试验、示范表明,在同氮量条件下,该专用肥在香蕉生长综合性状方面明显优于对照,产量比对照增产14.0%～31.9%,差异极显着,束顶病发病率降低7.9%.对施用后土壤中的pH值、容重、有机质、全氮和速效氦、磷、钾以及微生物群落的变化进行检测,结果该专用肥肥效高且稳长,可改土肥田。根据市场需求,把新产品研究与开发结合进行,两年来,生产该专用肥300多t,施用面积266.7hm2,取得了显着的经济效益
Abstract:
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.
