Construction of meat duck breeding greenhouse

Greenhouse breeding refers to covering the open or semi-open livestock and poultry enclosure with a layer of plastic film in the cold season, making full use of solar energy and the heat emitted by the livestock and poultry themselves, raising the temperature in the house, reducing heat loss and reducing maintenance needs. improve livestock and poultry production performance and economic benefits of raising poultry. At present, many ducks are raised in plastic sheds with low input and high output, which have achieved better economic benefits. let's take a look at the construction method of meat duck breeding greenhouse.

Construction of Meat Duck breeding greenhouse

1, enclosure specifications: generally use double-row type, width 9.2 meters, length can be determined according to the situation, generally 30-50 meters, 1.2 meters in the middle of the passage, eaves 2.0-2.2 meters high.

2. Ground construction: a certain slope (0.6-1.0%) is required, preferably cement or brick floor, with internal drainage ditch and external sewage tank (biogas digester).

3, net bed construction: 40-50 cm from the ground to place the horizontal frame (or 10-15 cm to lay plastic net), row spacing 2-3 meters, laying rectangular bamboo blocks or water bamboo strips on the horizontal frame, length is multiple of horizontal frame row spacing, bamboo blocks are 2-3 cm wide, bamboo blocks (water bamboo strips) are 5-10 cm apart, plastic nets are laid on the net beds, and generally the duck houses after brooding are laid with 25 × 25 mm plastic mesh.

4. Roof construction: small green shingles or grass curtains + asbestos tiles are used for roofs.

5. Feeding trough setting: the sink can be made separately from the plastic accumulated water pipe with a diameter of 25 centimeters. 5-10 centimeters away from the net bed, it can be placed against the wall or covered with a plastic basin with a diameter of 40-50 centimeters and placed on the net bed. The feeding trough generally uses the "bucket" type feeding trough, with the upper mouth 50-60 cm long and 30-40 cm wide. The lower mouth is 50-60 cm long and 10-20 cm wide. The specification of the base is the same as that of the upper mouth, 40-50 cm deep.

Matters needing attention in greenhouse construction

1. Location: the greenhouse for large-scale duck farming should be built in a place with leeward to the sun, good drainage, convenient transportation, close to water sources, high terrain and dryness. In order to make full use of solar energy, it is best along the east-west direction.

2. Construction: the shed is arched, the height should be more than 2 meters, the length and width depends on the breeding scale. Selected diameter 25 mm, wall thickness 1.35 mm welded pipe, bent into a semicircle as a support, each two as a group, using a diameter of 30 mm, wall thickness 1.5 mm casing secure. After installing the bracket according to the specifications during the construction of the shed, fix the bracket on each bracket with a stick or steel pipe, and then fasten the bracket for 3 to 5 rows with bamboo pole and steel wire, and set up one column every 2 to 4 meters. After the scaffolding is completed, grass curtains are laid on it, and then covered with plastic film, and then covered with 70% / 80% sunscreen. It is best to use a cable to seal the shed so that it can be rolled up, exposed to sunlight and ventilated. It should be noted that movable doors should be set up at both ends of the greenhouse.

3. Scaffolding: the scaffolding used for raising meat ducks is made of bamboo or bamboo slices, each 2 meters long and 0.5 meters wide. The bamboo slices are divided into two types: flat and flat, which can be worn firmly with small round steel bars. When making, the edges and corners should be cut off and the forks should be trimmed to prevent ducks from being hurt. If the plastic cushion net can be laid on the scaffolding to increase elasticity, the effect will be better. The scaffolding is 30 to 40 centimeters above the ground and is required to be laid smoothly and firmly during installation.

4. Operation: meat ducks are raised in the scaffolding. From 9: 00 a.m. to 4: 00 p.m. on the sunny side in winter, the grass curtain can be rolled up and exposed to sunlight to keep the temperature in the shed in the suitable range of 18 ℃ ~ 20 ℃. Sooner or later, the grass curtain will be covered to achieve the purpose of raising the temperature, saving fuel and saving feed. On cloudy and snowy days, the greenhouse is covered strictly with grass curtains, and the roof is ventilated irregularly according to the temperature, humidity and air pollution in the shed. Due to the laying of scaffolding in the shed, not only the suitable growth temperature is maintained, but also off-ground feeding is realized, and the incidence of ducks is significantly reduced. However, it should be noted that the construction of the greenhouse must be firm and durable, the temperature and air turbidity should be closely observed in breeding, and it should be adjusted by opening the roof at any time, so as not to suffocate the meat duck by sealing for a long time.

Construction cost of breeding greenhouse

1, the ground: the ground adopts concrete ground (5cm thick, aisle 10cm thick, need (8m × 40m × 0.05m) + (1.2m × 40m × 0.1m) = 20.8m3 (concrete), the artificial wage of hitting the ground is 8 yuan / sqm, the cost is 20.8x375mm / 7800 yuan, the apportion unit price is 7800 / 36800RMB / sqm = 29.2RMB / sqm.

2. Foundation: one layer of bluestone is used in the foundation, which requires bluestone (9.2m + 40m) × 2 / 0.8m = 123m, 123m × 20yuan / m = 2460 yuan, and the apportion unit price is 2460 yuan / 368m2 = 6.7RMB / m2.

3, brick column: the spacing of brick column is 4 meters, the outer column is 48 × 48, the inner column is 36 × 36, each 18, need (0.48x0.48x2.2x18) + (0.36x3.2x18) = 16.59m3 (brick column), the cost is 16.59m3 × 315.6 yuan / m3 = 5236 yuan, the apportion unit price is 5236 yuan / sqm = 14.2 yuan / sqm.

4. Fence: the height of the fence is 1 meter (60 cm above the net bed), the area is 1 × 80 square meters, the cost is 80 square meters × 57.6 yuan / square meters = 4608 yuan, and the share is 4608 yuan / 368 square meters = 12.5 yuan / square meters.

5. Duck shed: duck shed end wall area (9.2m × 2.2m + 9.2x1.2m / 2) × 51.52m2, cost 51.52m2 × 57.6RMB / sqm = 2968 yuan, apportion 2968 yuan / sqm = 8.1RMB / sqm.

6. Net bed: 30 yuan / square meter (plastic net 12 yuan / square meter, bamboo frame or reinforced concrete frame 18 yuan / square meter).

7. Roof: glazed tile 80 yuan / square meter, small green tile 70 yuan / square meter, asbestos tile plus grass curtain 40 yuan / square meter, double layer color steel 140 yuan / square meter, single layer color steel 100 yuan / square meter.

8. Dung treatment: sand settling tank → biogas tank → oxidation tank → was discharged to fish ponds. 10, 000 ducks, build sand settling tank 40 cubic meters → biogas digester 100 cubic meters → oxidation tank 60 cubic meters

Total: the construction cost of breeding greenhouse is 68000 yuan, feed house 50 square meters × 340 yuan / square meter = 17000 yuan, water well 5000 yuan.
