In 2008, the Shangxia Habitat Agricultural Technology Information Center in Shangyu City, Zhejiang Province implemented a technology-based household development process to store a farmer with 5 acres of ponds. 720 kg of fresh shrimp, 180 kg of white peony, total output value of 3861 O yuan, total net income of 21,860 yuan. The main technical measures are now described as follows: The pond sited pond is located in Renxia Village, Zhenxia Town, Songxia Town. The soil quality is loam, close to the water source, sufficient water supply, good water quality, convenient irrigation and drainage, no pollution source within 3 km, and the water quality meets the standard requirement of NY5051, in which the dissolved oxygen reaches 5 Mg/L, pH around 7.5, convenient transportation and electricity. The Pond Condition The pond is rectangular, east-west, slope ratio l:3, the bottom of the pool is slightly inclined towards the drain outlet, the pond mud is 10 centimeters, and water can be injected 1.5 meters, with an area of ​​5 acres. The pond is equipped with a 1.5-kilowatt impeller-type aerator and a 2.2-kilowatt submersible pump, and has a perfect intake and drainage system. There is a net fence around the ear water outlet, and the inlet and outlet openings are each wrapped with sieve boxes over 60 months to prevent wild fish and other predator organisms from influxing with the water and causing the shrimps to escape. Qingtang disinfects and cleans ponds, drains pool water with a pump, removes excess sludge, retains 10 cm, and after exposure to fire, disinfects with 60 kg of quick lime. Use 100 kg per mu. Diluting the lime with water to make the pool evenly spilled. Then, stir and mix the silt and lime in the bottom of the pool with shovels to completely kill the wild fish, pathogens and pests in the pond. New water was poured on February 15 and 60 cm of water was poured for the first time. In order to cultivate sufficient plankton and benthic organisms, a total of 1500 kg of fermented and decomposed organic fertilizer was applied 7 days before the seedlings were planted in the lower pond. The amount of 300 kg per mu was used. Before stocking the second batch of fresh shrimp, all the fresh shrimps and white fishes in the pond should be out of the pool, and the tea seed cake can be stocked again after clearing the pond. At the end of February, the stocks were stocked at 2500/kg, the body length was 2.5 to 3 cm, and the stocking rate was 12 kg/mu, which was approximately 30,000. Before stocking, soaking in 2% to 3 minutes with 3% saline solution, the stocked juveniles are free from disease, injury, body surface, clean, no attachment, bright body, appendages, strong vitality, and basic specifications. And let it go once. At the same time, appropriate amount of filter-feeding fish was provided in the pond. After 10 days, a total of 100 species of large-scale species of flower calyx and 200 species of white storks were adopted. In August, the second batch of shrimps was stocked with a total of 3,000 to 4000 tails per kilogram, a body length of 1.5 to 2 centimeters, and 13 kilograms per acre, which is approximately 45,500 tails. The shrimps are uniform in size and robust in physique. After being sterilized, they enter the pool, and half a month after they are released, a total of 1200 species of summer fishes are cultivated. Shrimp were soaked with salt 3# for 2-3 minutes before stocking. The "shrimp nest" was set up in a shallow water zone 2 meters from the shore of the pool along the pool and in the pool. It was planted with aquatic plants such as peanuts, water spinach and water lettuce. The width of the grass was 1 meter. The water single belt was fixed with ropes to avoid The wind floats. Water grass. Before entering the pool, disinfect with bleach or copper sulphate solution to prevent enemies such as yellow clams, crayfish and wild fish from entering the pool. Aquatic grasses account for about 25% of the ponds. When aquatic plants thrive in summer, they will affect the photosynthesis of the surface air permeable and phytoplankton. Too much water weeds must be removed. The first catch of commercial shrimp was caught in late May and the second batch of commercial shrimp was caught in late October.
