In the paddy fields, squid are stocked so that the squid can eat various aquatic animals and plankton in the paddy fields. In particular, harmful animals such as snails, snails, and rice pests in the rice fields can not only make the carp grow fast and grow quickly, but also increase quickly. Heavy, fast fattening, and normal growth of rice, reduce the investment in pest control, so that rice can obtain high yields, but also protect the environment. It is understood that in the rice field, squid stocking, each squid weighing about 100 grams, breeding 3 to 5 months, can be increased to about 400 grams, no need to feed other feed, and rice yield is still more than 450 kilograms per The investment cost per mu is reduced by more than 30 yuan. The paddy field grazing techniques are as follows: First, water storage. In the spring before inserting a good amount of water, all along the field, dig deep and 30-40 cm in width along the side of the paddy field, shovel the dirt on the field ridge, and raise the field rake to prevent the squid from escaping. At the same time, dig deep and wide cross-shaped symmetric deep trenches with widths of 30-40 cm in the paddy field and connect them with the side ditch so that the squid can move in the deep ditch and side ditch. Second, the kind of rice. After the paddy field is filled with water, rice can be planted in the paddy field. In addition to the side ditch and the cross deep trench, seedlings are not inserted, and all other places are planted with seedlings. The seedlings are ploughed before the seedlings are transplanted to loosen the mud. Each 15 to 20 kilograms of superphosphate or calcium magnesium phosphate fertilizer is applied per acre of paddy fields. Fertilizer fertilizer is beneficial to the growth of rice, and it also increases the number of aquatic animals, which is conducive to the growth of carp. Third, put the fish. After inserting the seedlings for about 7 to 10 days, when the seedlings return to green and begin to grow, they can be used to feed squid. Usually about 250 to 300 squid weights of about 100 grams per acre are selected, and they are robust, disease-free, non-invasive and lively. When the squid is released, let the squid swim in the 25 to 30 times garlic leaching solution for 3 to 5 minutes before disinfecting, and then put it into the side ditch. Fourth, prevent escape. After stocking squid, care should be taken to prevent squid from escaping. In addition to paying attention to heightening and strengthening the field ridges, and preventing heavy rain, the Tiantian Water should be allowed to pass over the field ridge or field ridge. p The collapse of the squid should be completed by installing a drainage port and installing an anti-escape net so that the rain can be eliminated in time. Lot of water. Fifth, prevent disease. In paddy fields, squid stocking rarely occurs, but usually precautions should be taken. Normally, dry and pure plant ash should be sprinkled into the fields every half a month. Spread 3 to 5 kilograms per acre and sprinkle in the ditch and cross ditch. can. Or spit once every two weeks EM bacteria solution, each sprinkling 800-1000 ml per acre, diluted 15 to 20 times, splashed in the side ditch and cross ditch. Sixth, rice disease prevention insecticide. After paddy fields have been stocked with carp, do not use herbicides and molluscicides in the rice fields to avoid harming grass carp. If pests such as rice planthoppers, leaf roller insects, drill insects, sheath blight, and rice blast are infested, "insecticide-insecure fish", "blue beidou", "matrine", and "quergiline" can be used. "High-efficiency and low-toxicity pesticides such as Jinggangmycin" and "Thiococcus" are used for prevention and control, which can both prevent and kill insects and do not harm cod. Seven, capture. Using paddy fields to raise squid, they can be caught when the rice is mature and harvested. When catching, put the dry field water first, so that the squid can all enter the side ditch and cross ditch, and then manually capture.
