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 gutter 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 were stocked one week after transplanting. Generally, larvae were bred in the year of breeding, and 667 m2 was planted with 1-20000 tails. 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%~4% of shrimp's 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, we must especially prevent predators, such as water snakes, frogs, mice, water birds.
Rice paddy shrimps are used for catching water. The nets are used to arrange the water outlets at the outlets. Slowly dry the field water to allow the shrimps to enter the net with the water and capture the shrimps in the shrimp ditch.
