【摘要】 试验结果表明,保水型有机肥通过改良土壤结构,提高土壤的持水能力,在旱坡地形成适宜香蕉生长的良好的水分和养分供应环境,有利于肥料养分吸收和水分利用,从而促进香蕉的健壮生长,减轻水分胁迫的影响,并可节约灌溉水,与香蕉专用肥比较,增产13.9%,增收4425元/hm2,节水25%。试验结果预示着保水型肥料在旱坡地香蕉生产中应用是一项有效的增产增收措施。更多还原

【Abstract】 A field trail was conducted to study of water-retaining organic fertilizer on banana in sloping field.Results showed that the sloping field could offer the better environment of supplying water and nutrients for the growth of banana after applying water-retaining fertilizer,because of amending soil structure and heightening soil water retaining capacity,thus the growth of banana was vigorous and the water stress was alleviated.In comparison to the specific-fertilizer,the treatment of applying water-retaining fertilizer increased the yield and income up to 13.9%,4425 yuan/hm~2 respectively,in addition to saving irrigation water by 25%.These results mean applying water-retaining fertilizer is an effective measure for banana production in sloping field.更多还原
