不同类型绿化废弃物与羊粪豆渣共肥效果研究

选取郑州植物园内的枯枝、落叶为试材，采用好氧堆肥技术，在粉碎绿化废弃物中添加不同比例的羊粪和豆渣，通过制肥设备进行初次发酵，随后进行二次堆肥发酵至腐熟。检测了有机质、pH值、养分含量、发芽指数等指标，筛选出最佳的堆肥发酵配方。结果表明从堆肥进度上，A3、A4处理优势明显，堆肥时间最短，发芽指数、T值、养分含量均符合要求；从堆肥产品质量上，A1处理优势明显，总养分和发芽率较高，pH值、T值、EC值符合有机肥要求；从经济适用性上，A1、A3处理优势明显，发芽率较高，养分含量丰富，堆肥时间适宜，且需要的羊粪含量较低，更加具有经济适用性。

Study on Effect of Co-fertilization of Different Types of Greening Waste,Sheep Dung and Bean Dregs

The dead branches and fallen leaves in Zhengzhou Botanical Garden were selected as test materials, and the different proportions of sheep dung and bean dregs were added to the crushed green waste by aerobic composting technology, the compost was then fermented for a second time until it was ripe. The organic matter, PH value, nutrient content and germination index were tested to select the best compost fermentation formula. The results showed that the treatment of A3 and A4 had obvious advantages in terms of composting schedule, the composting time was the shortest, the germination index, T value and nutrient content were in line with the requirements, and the treatment of A1 had obvious advantages in terms of composting product quality, with higher total nutrient and germination rate, the pH value, T value and EC value met the requirements of organic fertilizer, and the economic applicability of A1 and A3 treatment was obvious, the germination rate was higher, the nutrient content was rich, the composting time was suitable, and the required sheep dung content was lower, so it had good economic applicability. ;
