Composting of Separated Soil from Root Vegetables and Other Agricultural Residues and its Sterilizing Effect

从根蔬菜（糖甜菜）中分离的土壤不仅含有有机物质和植物的营养，而且还有很多病原菌。“因为这一原因，它不能返回农场土地，而不需要在订购时进行类固醇化治疗，以防止细菌的扩散。”使用微有机体进行类固醇化的方法是预期的低成本和大规模治疗。这个项目已经完成了找到一种实用的类固醇化方法，使用分离的土壤从编辑中产生热量。该综合体如下;1.当糖甜菜制造浪费包括分离的土壤可用时，如合成、优化操作条件等;混合率（重量）;分离的土壤：剩余的水分： CSF（集中的苯乙烯过滤）：小麦秸秆= 81：13：2：4，水分含量; 45%wd。Aeration rate min.kg吹风机14分钟。20 min.cycle.2.要迅速地提高复合温度，材料温度应至少维持在5 ° C以上，如果可能高于10 ° C。杀死病原体的结果是时间和温度的结合。病原体完全被杀死，如果复合物的温度在3周内保持55 ° C。即使在最寒冷的冬天，复杂的温度也会迅速上升，如果上面的操作参数在最佳范围内。但表面或底部部分与中央部分之间的温度差异可能在没有充分绝缘剂的情况下经常产生。堆肥后分离的土壤具有较高的pH值，抑制植物的生长，但在修复后对植物的生长和疾病抑制有很好的影响。这种强制性的空运沥青方法可以应用于每一种农业住宅的合成，作为一种散装剂，就像一根粗钢或木质芯片一样可用。

Separated soil from root vegetables (Sugar beets) contains not only organic matter and nutrition for plants but also a lot of pathogenic bacterias. Because of this reason it can not be returned to farm lands without sterilizing treatment in order to prevent diffusion of bacterias. A sterilizing method using microorganisms is expected to be a low cost and mass treatment.This project is carried out to find out a practical sterilizing method of the separated soil using heat generated from composting.The conclusions are as follows;1. When sugar beet manufactoring wastes which include separated soil are available for composting, optimum operating conditions are as follows; Mixing ratio(weight); Separated soil: Surplus sewage sludge: CSF(Concentrated Steffen Filtrate): Wheat straw = 81:13:2:4, Moisture content; 45% wd., Aeration rate; 0.5 1/min.kg DM, Aeration time; Blower on 6 min., Blower off 14 min., 20 min. cycle.2. To begin to raise temperature of compost rapidly, material temperature should be maintained above at least 5゜C, if possible above 10゜C.3. Killing of pathogens results from a combination of time and temperature. Pathogens are killed completely if the temperature of compost is kept above 55゜C for 3 weeks.4. Temperature of the compost rises rapidly during even the coldest winter, if the above operating parameters are within optimum ranges. But temperature difference between surface or bottom part and central part may often arise without sufficient insulators.5. The separated soil after composting (Produced compost) has a high pH value and inhibits germination of plants, but after curing it has very good effect on plant growth and disease inhibition.6. This forced aeration pile method can be applied to the composting of every agricultural residue as long as a bulking agent like wheat straw or wood chips is available.
