生物有机肥的研究与应用效果分析

Research of organic manure and its effect analysis

针对城市污水处理厂污泥含有作物生长所需的氮、磷、钾等营养成份和大量有机质 ,可以充分利用到农业生产中的实际情况 ,本文提出了采用特定的微生物菌群 ,以污泥为微生物能量物质生产生物有机肥的新技术 .田间实验表明 ,制成的生物有机肥有较好的增产效果 ,并可以改善土壤结构 。

The sludge discharged from urban wastewater treatment plant contains necessary elements for crop growth such as N, P, K and other nutrients and organic humus which can be used for agricultural production. In this paper ,the authors introduce a new technology to produce organic manure by particular microbe mass and the energy made by sludge. The field experiment shows that this kind of organic manure has a favorable effect on increasing production. Besides,it can also improve the fabric of the soil and its ability to fertilize the soil.
