摘要
以园林植物废弃物为原料,采用高温好氧堆肥技术,运用正交实验研究了含水率、C/N、菌种和翻堆对堆肥的影响。结果表明:基于种子发芽指数的适宜参数是含水率51.2%、C/N30.9、菌种用量10 g/kg、翻堆时间5 d,4个因素对堆肥影响的大小顺序是:含水率、C/N、翻堆时间、菌种用量。堆肥过程堆料体积缩小,pH和EC值升高,堆肥成品具有一定的肥力。
The physicochemical characteristics and technics on composting of the green waste were studied. The results showed that the optimal parameters on composting of the green waste for germination index were：water content 51.2%, C/N 30. 9,10 g/kg bacteria dosage and 5 days turning frequency,which were determined through the orthogonal experiment. The effect of composting was water content〉C/N〉turrfing frequency〉bacteria dosage. The volume of the piles were reduced, the pH and EC were increased, the compost product had certain level of fertility.
