Outdoor fly maggot breeding technology

Outdoor fly maggot breeding technology

Although the production of fly maggots is lower than that of the three-dimensional fly maggots, and it is not as stable as the three-dimensional fly maggot breeding, it is currently the most popular for most students because of the advantages of less investment, quicker efficiency, no introduction, no need to feed the fly, and low cost. s Choice.
The suitable season for outdoor fly maggot breeding is generally from the end of April to the middle of October each year.
First, the construction site of the simple farming room is recommended to choose away from the living area, there are shade but there is a certain light, more places in the wild flies. The area should be determined according to the required output. According to the production experience, the average output per square meter is about 0.5 kg. As long as the breeding room can cover the rain, thatched house, cement tile house, bark house will do. Around the house, a screen with a height of 1 meter should be used to prevent animals such as chickens and ducks from entering. The aquaculture ponds require simple cement pools, each with an area of ​​1.5 to 2 square meters and a poolside height of 20 cm. The specific layout is shown in the figure. The tiles are connected by endless ropes that cross back and forth to allow the flies to rest on them.
Second, the preparation and placement of fecal material 1. Fresh pig manure (pig within 3 days of the next) 70%, chicken manure (in a week) 30%; 2. Fresh pig manure slaughterhouse 100%; 3. Pig manure 75% , 25% of bean curd residue; 4. Chicken manure 50%, pig manure 25%, bean curd residue 25%. Mix the above manure, add 1 kg of EM per tonne of manure, and the water content is 100% (feeling that the manure is not deformed at a height of 20 cm), cover it with agricultural film, and use it after 24 to 48 hours. Due to outdoor farming, fecal material can also be directly fed into the culture tank without fermentation. The fermented manure was sent to the mortuary and three pilings were placed in each pool. Each bar was 0.8 meters long, 0.2 meters wide, and 0.15 meters high. The dropping time is 4 to 5 pm every afternoon.
Third, the preparation and placement of oviducts As it is outdoor breeding, oviducts can be more choices, you can put dead fish directly on the dung heap, can also be formulated according to the following formula: 100 kg of manure calculated: wheat bran 1 kg, 2 fishmeal, 2 peanut bran, 1.5 kg of water. After mixing, it can be placed on the dung heap. After placing the egg, it is forbidden to walk around the pool.
Fourth, the daily management of fecal material put away, set the egg (the first few days is best to dead fish or fish viscera to attract wild flies come) put, in the wild where more flies generally gather eggs within half an hour A large number of flies are spawned on the object. At 9 o'clock in the evening, a small layer of eggs is used to cover the egg masses produced by the fly to increase the hatching rate and reduce the damage of ants and other insects. The eggs of the fly will hatch in the next morning. In 36 to 48 hours, the fly larvae have scattered the previously neat piles. The fly larvae, which grew up first in 72 hours, climbed out of the dunghill and were automatically separated. In the harvesting barrel, generally the fly maggots in the manure have been completely separated on the seventh day.
Assuming that you have a total of 14 Dianchi ponds, you should enter two pools per day. Fill all the ponds on the seventh day. On the eighth day, shovel out the remaining manure from the fly larvae on the first day and replace them with new ones. This cycle of production.
10:00 am Pick up the fly maggots from the harvesting bucket, shovel out the remaining excrement from the fly maggots, loosen the other pools by the fly maggots, and pile the manure in the dunghills on the poolside to avoid meeting. There is no clear path for the separation of fly maggots.
Outdoor simple fly maggot breeding does not require feeding. However, in order to allow the fly to stay in the vicinity of the raising room, it is necessary to put new feces and oviducts every day. The food of the fly is mainly derived from the manure and the oviposition.
Because fly maggots cannot be sterilized in outdoor fly worms, too much EM can be used in the feces to eliminate odors and sterilize. Therefore, the fly maggots cultivated must have many harmful bacteria. Seven parts of potassium permanganate was soaked in water for 5 minutes and then fed to economic animals.
V. Output Each person can manage an area of ​​150 square meters. Generally, about 150 kilograms of fresh fly larvae per ton of manure can be produced. No power is needed, and the cost is extremely low.
Sixth, the issue of yield stability is not as steady as a three-dimensional fly aquaculture farm. It takes more than two days to recover after a heavy storm.
