随着我国城市绿化快速发展,园林废弃物的产生量日益增加,好氧堆肥处理已成为园林废弃物资源化利用的重要方法。文章以苏州市为例的研究表明,园林废弃物以生长期和休眠期修剪枝叶为主。生长期修剪枝叶的含水率为57%~72%、碳氮比32~48,适合堆肥处理。生长期枝叶中添加玉米芯能增加易降解有机质的含量,提高堆体温度,加速堆肥的进程。该研究结果可为长三角地区园林废弃物的处理处置提供参考和依据。
With the rapid development of urban greening in our country, the amount of garden waste generated is increasing day by day. Aerobic composting has become an important method for resource utilization of garden waste. The article takes Suzhou City as an example and studies show that garden wastes are dominated by pruning branches and leaves in the growth period and dormancy period. Pruning branches and leaves during the growth of water content of 57% to 72%, C / N ratio of 32 to 48, suitable for composting. Growing branches and leaves to add corn cob can increase the content of easily degradable organic matter, increase the temperature of the pile body, accelerate the compost process. The results of this study can provide reference and basis for the treatment and disposal of garden wastes in the Yangtze River Delta.
