Rice field cages

First, after the harvesting of the early rice, the cage is set to select the paddy fields where the water source is safe, the water quality is not contaminated, and the water injection and drainage are convenient. The width of the field is increased to a depth of about 1 meter. The area can be varied from small to large. For management considerations, rice fields with an area of ​​3 to 5 mu are generally selected. The cages are sewn with dense-eye polyethylene mesh sheets and have an area of ​​about 15 square meters, a rectangular shape, a specification of 10 meters, 1.5 meters and 1.2 meters, and a box height of 1.2 meters, of which the water part is 50 centimeters and the underwater part is 70 centimeters. The cages are arranged in a single row or in multiple rows. Each column is separated by 1m to 2m. The caged peanuts are inhabited by A. persicae, and the area of ​​water peanuts accounts for 90% of the cage area. The proportion of cage area to surface area does not exceed 35% to facilitate water quality control.
Second, stocking seedlings Usually, from July to August began to put seedlings. The seedlings are mainly derived from natural wild seedlings. The collected seedlings are separated by large, medium, and small, and the same specifications are put into the same cage. The stocking amount is 2 kg per square meter, ie, each cage is raised by 30 kg. . The purchased seedlings are often injured. When stocking, they must be sterilized with 3% saline. Before stocking, bleaching powder or quicklime should be used to sterilize the aquaculture water to prevent wounded seedlings from infecting bacterial diseases.
Third, the feeding pipe nets The main feed for raising clams is clams, small fish, shrimp, and bean cakes. Usually, fresh clams are added at a ratio of 1:1 to full-price clams (or bean cakes, bran, etc.) Materials) Mixed feeding. There are nocturnal habits in the Astragalus mongolicus. Feeding should be carried out between 4 and 6 o'clock in the evening. Feed once a day, the bait rate is controlled at 5% to 7%, and the feed should be placed on aquatic plants. The remaining feed should be removed in a timely manner. Waterproof mice should bite and break the cage for the leftover bait. In addition, in order to prevent deterioration of water quality after feeding high-protein feed, a small amount of flowers and white mullet species should be raised in the aquaculture water and the water should be changed regularly. Pool water can not be too clear, otherwise it is easy to have grasshoppers. At the same time, it is necessary to maintain the stability of the water level, and the frequent changes in the water level will make the jaundice less secure.
Fourth, the prevention and treatment of disease after the normal intake of Astragalus, every 7 days to disinfect the body of water, commonly used drugs are lime, bacteria must net, bleaching powder and so on. At the same time, oral prophylactic drugs were administered with garlic 250 g to 500 g bait per 100 kg of baicalin, once a week.
V. Fishing Listed When Huangqi has a weight of 80g to 100g, it can be caught and listed. The best sales period of Huangqi is around New Year's Day and around the Spring Festival. At this time, the price of Huangqi is the highest, and fishing is also carried out at this time. The cages in the paddy fields are harvested and sold for the harvest of the yellow peony to earn a seasonal difference.
