Fish, pigs and grasses are a kind of efficient and comprehensive fish farming model. According to the principle of virtuous circle of ecology, the comprehensive cultivation method of fish and ragweed is implemented. In recent years, farmers throughout the country have succeeded in implementing the mode of breeding of ragweed. The use of fish ponds to raise pigs, pigs and urine to release fish ponds, can adjust water quality, fatten fish ponds; can reduce costs. Practice has proved that more than 200-250 kilograms of fish can be produced per acre, fish production can be increased by 100% to 200%, but also more production of pigs listed. Fish pond grass feeding fish can increase the fish grass material, so that the fish will grow faster and increase production. Its comprehensive rearing management techniques are as follows: 1. Three-dimensional and rational production layout. For general ponds, pigs and grass, the proportion of pigs per acre is 4 to 5 pigs per mu. Newly-built synthetic dwarf pens are used in ponds and ponds. Swine clams and swine urine flow into fish ponds, and new development of thin ponds and fattening can be changed. Water quality breeding methods: According to the size of fish ponds, 0.5 to 1 pigs per square meter of pigs can be raised, as well as increasing the amount of feeding. The rearing base (grassland) should be selected at the base of the base around the fish ponds, in the spring, grassy grasses, corn grasses, summer and winter rotations of ryegrass and shamrocks. ? Second, stocking fish species. After disinfecting and disinfection, middle and small-sized fingerlings should be placed. The stocked fingerlings should be four elephant fish, and the filter and omnivorous fishes such as Nile tilapia, freshwater squid, and hybrid squid should be the main types, and they can be used with grass carp species. . Stocking ratio: 40% for oysters, clams, squid, etc., 2500 to 3,000 for acre, 300% for oysters, clams, and tilapia, 2000 for medium and small Nile breeds, 1000 for hybrid carp, 1000 for freshwater carp , Carp 200; grass carp (carp) is 30%, generally mu in the size of carp 1000 ~ 1500 tail; medium size carp, carp 800 ~ 1000. ? 4 pond-based pigs: to raise the medium-sized pigs faster long glands, morning market. Every day, the pig barn sweeps the nets of pigs, cleans the pig houses and pigs, and cleans the environment of the pig houses. The pigs' urine flows into fish ponds. 5 base surface grass: in the pond base rake turn flat, open ditch, mu applied into the livestock manure 15-20 as basal fertilizer, planted in the spring short grass, corn grass, summer ryegrass, string grass, After 1 to 2 months of growth, when the height of the grass grows to 30 to 40 cm, the grass can be fed to the fish and the pigs can be fed. The fresh grass can be up to 2,500 to 3,500 kilograms per mu; the grass can be planted in batches after the first batch of grass is cut. Fertilization, growing to 30-40 cm and cutting the second batch, and so on, there can be a steady stream of green grass feeding fish, to achieve a healthy ecological cycle of fish, feed the pigs, so that fish, pigs long meat, can be mentioned in the morning market.
