Fish pond duck must be method

Duck ponds use polyculture of fish and ducks in adult and second-generation fish ponds. Generally without increasing the amount of feed and fertilizer, the fish can produce 100-250 kilograms of fish per acre, and can also produce duck eggs and duck meat.

Select the appropriate surface water surface generally use an area of ​​more than 1 mu, the depth of 1.5 to 2 meters of adult fish ponds and second-aged fish ponds, select suitable river ditch, small lakes, reservoirs can also be. The slope protection shall be constructed for the sand rake, the looser soil and the newly-drilled pond. In addition, the first-year fish ponds are generally not suitable for ducks, and rice fields are not suitable for polyculture.

Choosing the right way There are three main ways to implement comprehensive management of fish and duck at this stage: First, grazing. That is, the ducks are scattered on the surface of ponds or lakes and are returned to the duck shed in the evening. This method is conducive to large-surface fish breeding, but also can save some duck feed, but the effect of increasing the yield of fish is not. The second is the duck outside the pond. That is, a duck canopy is built near the fish pond, and a cement activity hall and an activity pool are set up. The duck manure and residual feed of the event are washed into the fish pond every day. This approach facilitates management in duck clusters, but it does not give full play to the symbiotic benefits of fish and ducks. The third is fish and duck polyculture. That is, a duck shed is built on the fish pond embankment, and a part of the pool pond is used as a playground to store the ducks directly on the fish pond. In this way, the ecological effects of symbiosis and mutual benefit between fish and ducks can be brought into full play.

To properly match the pond with ducks, it is generally advisable to put 100 to 150 ducks per acre of water. If more than 200 ducks are to be fed, it should be based on pupa, cockroach, tilapia, or pupa, pupa and other filter-feeding and omnivorous fishes. It is not appropriate to feed grasses, cockroaches, or herring. In addition, we must pay attention to changing water and oxygen. There should be no more than 250 ducks per acre of fish ponds, otherwise fish production will decline significantly.

Strengthen Feeding Management To facilitate management in duck clusters, use old mesh, screens, and other materials to surround a portion of fish ponds as a duck activity pool. It is better to raise 2 to 4 ducks per square meter of water. The height of the mesh is 40 in the water. ~50 cm so that fish can come in and out freely. Every morning and evening, ducks are fed at the Tiyu event venue. After the ducks enter the shed in the early evening, duck droppings and residual food on the venue are swept into the pool. In the morning, the ducks were released from the shed and the duck droppings in the shed were swept into the pool after the eggs were quailed. In summer, the duck population has a large amount of feces and the water quality is too fat. It is necessary to add new water in a timely manner and reduce the amount of fertilizer.

5A grade Huangjiu is adopted for Aged Wine,i.e. A grade raw materials, A grade timing, A grade pottery jar, A grade storage and A grade brewers. Using Huangjiu of the most representative years as base, aged wine is bottled in green porcelain for banquet and gift-giving. Glass-bottled-wine is mainly used for 3-5 years of ordinary wine, with superior cost performance, suitable for people who drink at home frequently.
