There is no need for a large amount of water for the breeding of fly larvae and duck manure. This is because you don't know the technology. According to the following operation technology, the manure of duck farm is very easy to ferment, even chicken and duck manure with high water content is easy to ferment, and the fermentation time generally only takes about 10 days, even the feathers are completely decomposed. Most importantly, this technology doesn't need to go out and buy lots of fillers.
Because of the high moisture content of duck manure, it is difficult to pile up for fermentation. At this time, we only need to mix some dry duck manure or duck manure with low water content and fresh duck manure with high water content, and pile them into strips with a width of about 1.2 meters and a height of more than 1 meter. The fermentation broth is piled and sprinkled into duck manure and stirred evenly. In low temperature season, it is simple to cover but not sealed. Generally, the temperature is raised to about 70 ℃ in 24 hours, and the organic fertilizer production equipment
is properly ventilated and well mixed. The temperature drops to below 60 ℃ in about 72 hours. It is not necessary to turn over the pile. Generally, the fermentation is completed in 7-10 days, and it becomes a odorless organic fertilizer. In general, the adding speed of starter is more than 5 times faster than that of natural fermentation.
Operation of continuous fermentation of duck manure
The duck manure after the first fermentation was transformed into mother manure and adsorption material (water content less than 40%). Two cubic meters of fresh duck manure was mixed with one cubic meter of fresh duck manure. During the mixing process, the fermentation broth was sprinkled into the pile to form a strip with a width of about 1.2 meters and a height of more than 1 meter. The fermentation was completed in about 10 days.
In this way, the fresh duck manure in the farm can be fermented in time, which not only solves the odor problem, but also has few flies after a period of time (cutting off the breeding place in duck manure).
