用漂浮植物水葫芦治理水体富营养化已经在我国获得大规模的应用,但目前对水葫芦资源化利用技术的研究相对较少。本研究采用不同的堆肥方式来堆置水葫芦和猪粪混合堆肥,以明确水葫芦和猪粪混合堆肥堆置的最适条件。在不同形状堆肥条件下,锥形发酵过程中升温既快又高,形成的堆肥品质和腐熟度优于长方形堆置方式。堆肥的高度越高升温越高,水分和养分流失越多,堆肥高度应适中。堆肥翻抛频率对成肥有着重要的影响,2 d翻抛1次比3 d翻抛1次对温度变化影响较大,2 d翻抛1次的处理腐熟度明显高于3 d翻抛1次的处理。综上所述,在水葫芦和猪粪混合堆肥过程中应采用锥形发酵,高度在1 m左右适宜,2 d翻抛1次,从而可获得高品质的有机肥。
The use of floating plant water hyacinth to control water eutrophication has been applied in large scale in our country, but at present the research of water hyacinth resource utilization technology is relatively few. In this study, different composting methods were used to pile mixed compost of water hyacinth and pig manure in order to clarify the optimum conditions for the composting of water hyacinth and pig manure. Under the different composting conditions, the conical fermentation increased rapidly and rapidly, and the compost quality and maturity formed was better than that of the rectangular pile. The higher the compost height, the higher the temperature, the more water and nutrients are lost and the height of the composting should be moderate. The frequency of compost turning and throwing has an important impact on the compost fertilization. Flour and dumping 1 d after 1 d has a greater impact on temperature change than flip fluttering 3 d, and the maturity of the treatment after 2 d overturning and throwing is obviously higher than that of 3 d. Times processing. In summary, conical fermentation should be used in the process of mixed compost of water hyacinth and pig manure. The height should be about 1 m and 1 d for 2 days, so that high-quality organic fertilizer can be obtained.
