Paddy field farming, paddy field ecological environment suitable for the growth of shrimp, can increase economic efficiency. It is necessary to select a field that is close to the water source, has convenient drainage and drainage, and has a good soil quality. In the field, a wide-ranging shrimp ditch with a width of 2 meters and a depth of 1 meter was excavated, and a shrimp ditch with a width of 1 meter and a depth of 0.8 meters was formed around the center of the field. Before rice transplanting, rice fields were cleared in Qingtian, and larvae could be stocked one week after transplanting. Generally, larvae were bred and 667 square meters were released from 1 to 20,000. Choose stocks in the morning on sunny or sunny days.
In order to obtain high yield, paddy field shrimp farming must be fed every day. The feed can use bran, soybean cake, snail shellfish meat, fish meat, etc., or compound feed, twice a day, mainly in the evening, and the daily amount is generally It is 2% to 4% of shrimp body weight.
In order to maintain fresh water in the shrimp ditch, shrimp farming in the paddy field must maintain regular water changes, especially during the high-temperature season in summer. After the rice is harvested, it is also necessary to keep the shrimp water level stable. Green prawns are particularly sensitive to pesticides and they should be avoided as much as possible. If they are used, they should also use highly efficient and low-toxicity pesticides, and pay attention to their use to prevent phytotoxicity. In addition, special precautions should be taken to prevent predators, such as the damage of water snakes, frogs, mice, and waterfowls. Paddy shrimps are harvested using water. The nets are used to arrange the water outlets at the water outlets, slowly draining the field water, and allowing the shrimp to enter the net with water. Shrimp shrimp shrimp will be captured.
