Winter greenhouse duck technology
In the cold winter weather, duck farmers in rural areas have kept ducks in addition to keeping a small number of ducks. In many places, no fresh ducklings were listed throughout the winter. Some duck farmers have been inspired to innovate the new ducklings technology in the winter season in the greenhouse. The breeding techniques are now described as follows: Site selection and construction of plastic greenhouses The greenhouses for large-scale ducks are built on leeward, well-drained, easily accessible, and near water sources. The high and dry areas are conducive to the full use of solar energy, and it is best to build sheds along the east-west direction. Shed arched, height should be more than 2 meters, depending on the size of long and wide depending on the size of the breeding. A 25 mm diameter, 1.35 mm thick welded tube was used. The stent was bent into a semi-circular shape for use as a stent. Each of the two groups was a set of 30 mm diameter and 1.5 mm wall thickness sleeves. After the scaffolding is installed according to the specifications, the brackets on each bracket are fastened with wooden sticks or steel pipes, and then the brackets are fixed in 3 to 5 rows with bamboo rafts and steel wires, and the pillars are established every 2-4 meters. One. After the scaffolding is completed, the straw curtains are laid on top, the straw curtains are covered with plastic film, and the plastic film is covered with 70%-80% sunscreen. It is best to use a cable to seal it tightly, so that it is easy to roll up, receive sunlight and ventilation. It should be noted that there are active doors on both sides of the greenhouse. Duck scaffolding production and installation The scaffolds used for breeding ducks are made of bamboo or bamboo pieces, each of 2 meters in length and 0.5 meters in width. The bamboo pieces are divided into two types: flat and flat. Cut corners and cut out the yoke to prevent injury to the duck. If you can lay a plastic mat on the scaffold to increase the flexibility during feeding, the effect will be better. Shelvings are 30-40 cm away from the ground and are laid flat and strong when installed. Operation methods and precautions Shelf ducks are reared on the shelf. From 9 am to 4 pm in the winter sunny day, one-third of the grass curtains can be rolled up to receive sunlight, so that the temperature in the shed can be maintained within a suitable range of 18°C ​​to 20°C. In the morning and evening, straw curtains will be erected to increase the temperature, save fuel, and save feed. In cloudy snow days, all the greenhouses are covered with straw curtains, and the ventilation and ventilation of the roof are usually opened and closed according to the temperature, humidity and air pollution degree in the shelter. Due to the laying of scaffolds in the shed, which not only maintains a suitable growth temperature, but also achieves off-site feeding, the incidence of duck populations is significantly reduced. However, it should be noted that the construction of greenhouses must be robust and durable. Breeding should closely observe the temperature and air turbidity, be adjusted at any time by opening the roof, etc., and avoid suffocating meat ducks for a long time.
