以鸡粪和稻草为原料,添加Rw酵素剂作为发酵菌剂,适当控制发酵的C/N、温度、含水量、pH值、通气等发酵条件,添加适当微量元素等添加剂,然后经过粉碎和造粒等工艺,得到苗圃专用有机肥料产品。工艺和产品指标:(1)最高发酵温度达50~56℃以上,持续5~7 d;(2)有机质含量51%(以干计),C/N为15∶1,总氮1.93%,总磷(P2O5)1.35%,总钾(K2O)1.75%,pH值为7.3,大肠杆菌16个/g,蛔虫卵死亡率>99%,完全达到了国家关于有机肥的标准。
Using chicken manure and straw as raw materials, adding Rw enzyme as a fermentation bacterium agent, controlling fermentation conditions such as C / N, temperature, water content, pH value and aeration, adding suitable trace elements and other additives, and then crushing and making Tablets and other technology, nursery special organic fertilizer products. Process and product index: (1) The maximum fermentation temperature is above 50- 56 ℃ for 5-7 d; (2) the organic matter content is 51% (dry basis), the C / N is 15:1 and the total nitrogen is 1.93% Total phosphorus (P2O5) 1.35%, K2O 1.75%, pH value 7.3, Escherichia coli 16 / g, roundworm egg mortality> 99%, fully meet the national standards for organic fertilizer.
