The invention relates to a preparation method of a rural toilet urn-shaped cement manure pit. The method can be used for effectively solving the problem of manure pit production for meeting the rural requirement. The method comprises the following steps of: mixing 22-27 weight percent of sulfate aluminum cement, 35-40 weight percent of sand and 35-40 weight percent of water together at the temperature of 0-35 DEG C to form a pasty cement mixture, uniformly coating the pasty cement mixture onto cloth of a urn-shaped die by using an arc cement tool, sticking a glass fiber mesh to the cement mixture surface, secondarily coating the pasty cement mixture onto the glass fiber mesh, pressing the glass fiber mesh to form a finished surface, and forming a urn body; and performing first water spray maintenance in 2 hours after the urn body is manufactured, stripping after 4 hours, performing second water spray maintenance after stripping, performing third water spray maintenance after 24 hours, performing final water spray maintenance after 48 hours, and airing to obtain a finished product. The method has the advantages of simple process, easiness for production, high production efficiency, high product strength, long service life, low cost, cleanliness, sanitation, energy conservation and no environmental pollution.
