粪尿为农村中最普遍广泛应用的氮素肥料之一,由于内含寄生虫卵及致病菌,因此,人粪尿就成为肠寄生虫及肠道传染病的重要传播途径。本文根据目前农村的技术设备条件,对粪便无害化处理后的肥效测定,提出简单的快速方法,使人粪尿肥效价值及时得到分析,有利于进行研究。除介绍氮肥分析方法外,由于游离氨对观察虫卵的杀灭情况,有一定的参考价值,还作了游离氨测定法和磷的速测法。
Excrement is one of the most widely used nitrogenous fertilizers in rural areas. Due to its inclusion of parasite eggs and pathogens, human excrement becomes an important route of transmission of intestinal parasites and intestinal infectious diseases. In this paper, based on the current technical conditions in rural areas, we put forward a simple and rapid method for the determination of the fertilizer efficiency after the harmless treatment of manure, and make the analysis of the value of human manure and urine in time, which is conducive to the research. In addition to the introduction of nitrogen analysis methods, as free ammonia on the observation of the killing of eggs, have some reference value, but also made free ammonia determination and phosphorus rapid test.
