In the paddy fields, squid are stocked so that the squid can eat various aquatic animals and plankton in the paddy fields. In particular, eating harmful insects such as snails, snails, and rice pests in the paddy fields not only enables the carp to grow faster, but also increases 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 paddy field, squid stocking, each squid weighing about 100 grams, breeding 3-5 months, can be increased to about 400 grams, without feeding other feed, and rice yield can reach 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, store water in the spring before inserting a good reservoir of water, in the field around the field to dig deep, wide 30-40 cm wide side ditch, the soil shovel on the field ridge, heighten the field ridge, to prevent squid escape. At the same time in the paddy field dig depth and width of 30-40 cm wide cross-shaped symmetrical deep ditch, connected with the side ditch, so that the carp in the deep ditch and side ditch activities.
2. 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 channel, the seedlings are not inserted. All other places are inserted with seedlings. The mud is loose, and 15-20 kilograms of superphosphate or calcium magnesium phosphate fertilizer is applied per acre of paddy field. Fertilizer fertilizer is beneficial to rice growth, and it can also increase aquatic animals and facilitate the growth of carp.
Third, put the fish into the seedlings 7-10 days after the seedlings, seedlings turn green to start growing, you can put the squid, generally per mus of rice field weight of about 100 grams of 250-300 squid can be selected, choose robust, disease-free, no Injury and lively squid launch, when put, first allow the squid to swim in 25-30 times garlic leaching solution for 3-5 minutes to disinfect, and then put it into the side ditch.
Fourth, after the eel has been raised and escaped, care must be taken to prevent the eels from escaping. In addition to paying attention to heightening the field ridges to prevent heavy rain, the Tiantian water should be allowed to pass over the field ridge or field ridge. p. Excessive field water can be eliminated in time.
Five, disease-proof paddy field stocking carp, rarely disease, but usually pay attention to prevention, generally should be every two weeks to the field and sprinkle a dry and pure plant ash, 3-5 kg ​​per acre sprinkled each time, sprinkle in the ditch and cross Deep groove can be. Or spill the EM bacteria aqueous solution once every two weeks, sprinkling 800-1000 milliliters per acre each time, dilute 15-20 times, and splash it in the side ditch and cross ditch.
Six, rice disease prevention Insecticide rice fields after the stocking of herring, do not use herbicides and molluscicides in rice fields, so as not to harm 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.
VII. To catch salmon in paddy fields and capture rice when it matures. 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.
