摘　　要：通过固定猪粪添加量,依次增加桉树皮添加量,减少香蕉茎秆添加量,研究了桉树皮、香蕉茎秆和猪粪不同配比,不同C/N比值等对堆肥温度、pH值、微生物数量以及种子发芽率等堆肥发酵指标的影响,并用腐熟的有机肥进行香蕉幼苗盆栽试验。结果表明,堆肥材料C/N比值为25.24和27.01的处理堆肥温度较高,均达到56℃以上,持续高温时间分别为10和11 d,堆肥中各养分含量相对较高,达到NY 525—2012《有机肥料》标准。盆栽试验也表明,利用堆肥材料C/N比值为25.24和27.01的堆肥配制的有机肥对盆栽香蕉幼苗有一定的促生效果。A composting experiment was carried out,using fixed proportion of swine manure,increasing proportion of eucalyptus bark and decreasing proportion of banana stem,to explore effects of ingredient ratio and C /N ratio on composting temperature,pH,number of microorganisms,seed germination rate and some other composting fermentation indexes,and followed by a pot experiment to test the effects of composts different in ingredient ratio on growing of banana seedlings. Results show that when C /N ratio of the composting material was 25. 24 or 27. 01,the heaps of compost were the highest in temperature,reaching up to 56 ℃ or higher and maintained the high temperature for 10 and 11 days,respectively,and they were also higher in content of nutrients,and up to the criteria of the national standard(NY 525—2012) for organic manure. The pot experiment also shows that composts out of the two formulas had a certain growth-promoting effect on banana seedlings.
