【摘要】：针对大量堆弃煤矸石造成的严重环境问题,研究胶质芽孢杆菌和多粘类芽孢杆菌作用于难以被植物利用的硅酸盐矿物,将其转化为煤矸石矿物肥料,并研究了堆肥过程中的固液比、堆肥时间、环境温度、硅酸盐细菌混合比例等因素对煤矸石矿物肥料品质的影响。研究表明,当采用混合菌悬液1∶1,控制固液比1∶1(湿润),25°C下堆肥15 d时,矿物肥料中的有效磷含量和速效钾含量较高,是原煤矸石样品中含量的5.12倍和2.01倍。
[Abstract]:In view of the serious environmental problems caused by a large number of waste coal gangue, the effects of Bacillus glia and Bacillus polyphylloides on silicate minerals which are difficult to be used by plants are studied and turned into coal gangue mineral fertilizers. The effects of solid-liquid ratio, composting time, environmental temperature and silicate bacteria mixing ratio on the quality of coal gangue mineral fertilizer were studied. The results showed that the available phosphorus content and available potassium content in mineral fertilizer were higher when mixed bacteria suspension was used, the ratio of solid to liquid was controlled at 1:1 (wet), and compost at 25 掳C for 15 days, and the available phosphorus content and available potassium content in mineral fertilizer were higher. The content of raw coal gangue is 5.12 times and 2.01 times of that in raw coal gangue sample.
