Astragalus is delicious and nutritious and it is a valuable fish. In recent years, the resources of natural wild astragalus have decreased, and the market is in short supply. Therefore, the development of artificial breeding of Astragalus has broad prospects. The breeding base of Astragalus membranaceus in the famous Aquatic Research Institute of Macheng City has, through years of research and practice, used cages to grow Astragalus membranaceus with low investment and high yields. Its breeding techniques are as follows: 1. Cages layout ponds Reservoirs, reservoirs, lakes, and rivers may be fed with cages and yellow cockles, requiring a water depth of 0.7 meters or more, and convenient water drainage. Net cages are best made from polythene-free knotted mesh. Mesh hole size should be 0.6 to 1.3MM, mesh cage diameter 0.8CM above and below the cage, cage made of rectangular, cage area of ​​12 to 20 square meters is appropriate, too big and bad operation. The cage has a draught of 0.5 meters and the cage is over 0.5 meters above the water surface. 2. Buying Astragalus seedlings to cultivate Astragalus, seedlings is the key. Astragalus seedlings must be selected by workers to cultivate deep-yellow and large-spotted or golden-nosed varieties. They should not use variegated seedlings and seedlings that have not been trained, and they cannot believe that “special priests†and “Thailand’s giant crickets†should be used. The size of the yellow seedlings is preferably 30 to 60 per kilogram. The cage stocking density is generally best at 1.5 kg/m2. 3. Feeding management 1. Cage preparation and seedlings stocking Stocking 20 days before stocking with quicklime, 15 days soaking cages with 20PPM potassium permanganate for 20 minutes, placing water peanuts (revolutionary grass) or water hyacinth into the net The box grows, so that the grass can cover three-fifths of the cage and seedlings can be placed. When seedlings are stocked, they should be disinfected and soaked with drugs. When the water temperature is disinfected, the water temperature difference should be less than 2 degrees. Commonly used disinfecting drugs are: salt: the concentration is 3 to 5%, and the bath is 8 to 12 minutes.é³ é³ çµ : : 浓度 : : : 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 浓度 : : : : :. 2. Feeding the feed Astragalus seedlings are not fed 1 to 3 days after being placed in a cage. Feeding from the 4th to the 7th day is best. Feeding the feed every day at 6 to 7 pm is the best. At this time, the highest intake of Astragalus membranaceus, artificial cages feeding sturgeon feed to feed-based, appropriate feeding some cockroaches, snails, small trash fish. Feed directly into the cage in the water plants, so that the Astragalus feeding, compound feed can use Dajiang brand Astragalus full price material or Yangtze River brand Astragalus feed. Can also be self-made, formula: fish meal 21%, 19% cake, energy feed 37%, lotus root powder 12%, minerals 1%, mother 5%, multivitamin 2%, binder 3%, using Artificially cultivated dark yellow large-spotted turtle seedlings were fed with this compound feed, and the amount fed was 3 to 5% of the weight of the jaundice. 4. Prevention of rickets in cages to raise jaundice to prevent rickets. Astragalus after normal feeding, once every 10 days to disinfect the body of water, commonly used drugs are: Zhu Ling Ling. Turn legislation stop. The bacteria will do. Common rickets treatment methods; Hemorrhagic disease. Sprinkle or soak the stingray body for 30 minutes with Quanling Quanchipi, with an amount of 1.5 ml per cubic meter of water. Intestinal disease; Every 100 kg of scutellaria baicalensis is fed with 30 grams of garlic every day and fed for 3 to 5 days. Can not use the national banned drugs: for example, chloramphenicol, furazolidone. Macheng City Special Aquatic Institute for the long-term high-quality Saplings 56 yuan per kilogram, spawning species of Scutellariae 80 yuan per kilogram.
