【摘要】：【目的】掌握采用糖厂滤泥经功能菌发酵制成生物有机肥的特点和规律,为促进广西蔗区糖料蔗产业可持续生产提供技术支持,同时为政府制定农业种植环境保护相关政策提供决策参考。【方法】在广西重要蔗糖生产区(来宾市兴宾区和崇左市大新县)开展以糖厂滤泥为原料、发酵生产生物有机肥的田间试验,研究糖厂滤泥发酵生产生物有机肥的特征及肥效。【结果】采用功能菌发酵糖厂滤泥生产生物有机肥的腐熟速度快,受环境因素影响较小,发酵效果稳定,发酵温度最高达77.2℃,且70.0~77.2℃的维持时间长达12 d;发酵后的有机质含量和有机酸转化率优势明显,分别较传统(自然)发酵提高30.2%和12.3%(绝对值)。功能菌发酵生物有机肥对水稻、黄瓜和甘蔗有明显的增产作用,对应的平均产量分别为5971.5、76705.5和118780.5 kg/ha,较施等量传统(自然)发酵生物有机肥处理分别增产7.83%、41.19%和6.91%。施用功能菌发酵生物有机肥的土壤理化性状指标均高于施用传统(自然)发酵生物有机肥处理,其中土壤有机质、速效氮、速效磷和速效钾的含量分别为15.75 g/kg、67 mg/kg、14 mg/kg和69 mg/kg,而氮、磷和钾利用率分别为39.3%、12.8%和52.8%。【结论】采用功能菌发酵糖厂滤泥生产生物有机肥较传统(自然)发酵糖厂滤泥生产生物有机肥更具优势,具体表现为腐熟速度快、发酵温度高且保持时间长、发酵后有机质含量和有机酸转化率优势明显,同时具有增产、提高土壤肥力和肥料利用率的作用,生产上可大面积推广应用。
[Abstract]:[objective] to grasp the characteristics and rules of making bio-organic fertilizer by fermentation of functional bacteria from filter mud of sugar mill, and to provide technical support for promoting the sustainable production of sugarcane industry in Guangxi sugarcane region. At the same time, it provides a decision reference for the government to formulate policies related to the environmental protection of agricultural planting. [methods] in the important sugar production areas of Guangxi (Xingbin District of Laibin City and Daxin County of Chongzuo City), the filter mud from sugar mills was used as raw material. The field experiment of fermentation and production of bio-organic fertilizer was carried out to study the characteristics and fertilizer efficiency of fermentation of bio-organic fertilizer by fermentation of sludge from sugar mill. [results] the rate of decay of bio-organic fertilizer produced by fermentation sludge of sugar factory with functional bacteria was fast, and the effect of environmental factors was relatively small. The fermentation effect was stable, the maximum fermentation temperature was 77.2 鈩，
