First, the preparation. (1) Pond. The pond area is suitable for about 3 mu and the water depth is about 1.5 meters. It requires convenient drainage and drainage, good water quality, and exposure to ponds. There is a small pool of 200 square meters at the bottom of the pool. The small pool should be able to store 50 centimeters of water. Put water 50 cm deep into the pond 10 days before planting, and spray 150 kg of coarse salinized water in the pond about 3 hours before planting. When the water was released, the water was golden yellow, and there was a large amount of zooplankton in the water. (2) Base fertilizer. In April, 2 tons of cow dung were prepared and fully dried in the pool to reserve. Ten days before the release of shrimp seedlings, 50 kilograms of cow dung were released per acre by spreading dry cow dung at the foot of the pond and around the foot. Second, put seedlings. The seedlings were released in mid-May. The body length of shrimp seedlings was about 1 cm, and 30,000-35 thousand tails were stocked on each acre. Select good weather to put seedlings, it is best not to rain within 1 week after the seedlings or no significant cooling, which is conducive to improving the survival rate of shrimp seedlings. Purchased shrimp can not be directly placed in the pool, it should be connected to the bag on the surface of the shrimp pond, so that the water temperature in the bag and the pool water temperature is roughly the same, and then put. Three hours after the seedlings were released, suitable amounts of the feed were fed to the South American white prawn. Afterwards, 50-150 g of feed was fed per 10,000 tails and fed 3-4 times a day. Third, management. Shrimp seedlings were injected with water for 30 cm into the big pond for about 2 weeks, and after 50 kilos of coarse salinized water per acre, the whole pond was splashed with water. Then, the small pond was opened to several gaps to allow the shrimps and shrimps to swim to the big pool. When shrimps grow to a body length of more than 3 cm, prawn 250 grams of special feed is fed per 10,000 times per day. After the shrimps enter the big pool, they are injected with water once a week. Each time the water is injected 10-15 cm deep, when the shrimp body is about 7 cm long, 10,000 shrimps feed 1-1.5 kg per day, 8-9 am and 4 pm every day. When feeding each time. When the pond is rich in water, plus photosynthetic bacteria, each 2-2.5 kilograms per acre, Quanchiposa, if the water is light with fat fish treasure, about 3 kg per acre, Quanchiposa. Every time you add water, or after the next rain, use 30 kg of salty water per acre for Quanchiposa, and use 2.5 kg of calcium hydrogen phosphate per acre for Quanchiposa. Fourth, fishing. At the beginning of August, when the white prawn body is 10-12 centimeters long, it can be harvested and marketed. The net can be rounded or raked. In early October, the market for all dry pools ended. Best Black Tea,Black Tea Leaves,Organic Black Tea,Chinese Black Tea Hunan Junshan Yinzhen Tea Industry Co.,Ltd , https://www.junshan-tea.com
