Luzhou "soil experts" pass on raising Loach in Paddy Field

"Misgurnus anguillicaudatus seedlings are generally stocked before tillering, with 10000 to 15000 per mu. Before release, Loach seedlings are disinfected with light salt water." Recently, in a rice field of Loach cultivation in Baihe Village, Tianxian Town, Naxi District, Luzhou, Sichuan Province, Li Yunzhong, a "soil expert" and a "soil expert", was busy putting another batch of Loach seedlings into his paddy field. He explained with a smile: "Paddy fields raise Loach is studious, but to raise Loach well, the key is to master some basic skills, otherwise it will fail."

Li Yunzhong, an "soil expert", said that there is no problem in raising ecological Loach in rice fields as long as they master the following techniques to achieve a bumper harvest.

"the fields raising Loach generally require the selection of rice fields with good water sources, clayey soil, high fertility, no pollution, convenient drainage and irrigation, and easy to manage." Li Yunzhong said that the area of the rice field should be small, not large, the rice field should be surrounded by a hard ridge, and the ridge should be strengthened at the same time. Loach seedlings should be fully fertilized before stocking, and the rice field should be disinfected with quicklime.

According to Li Yunzhong, the varieties of Misgurnus anguillicaudatus directly affect its yield. therefore, the excellent seedlings of Loach with fast growth, strong fecundity and disease resistance should be selected. When digging fish ditch, according to the area of rice field, you can dig "cross" or "well shape", and the fish ditch channel should be smooth with the inlet and outlet. Li Yunzhong said that the fish ditch is generally dug in the middle of the rice field, accounting for about 15% of the rice field area, with a depth of 80 cm and a width of 100 cm. In this way, it can be used as a habitat or summer shelter for Loach when the water in the rice field is shallow or the water temperature is high in summer.

According to the experienced Li Yunzhong, to choose and buy excellent Loach seedlings, their body length should be at least 5 cm ~ 10 cm. The release time is generally from after transplanting rice seedlings to before tillering. After the Misgurnus anguillicaudatus seedlings are put into the rice field, they should be allowed to grow naturally, and can be fed regularly with soybean milk, flour, rice bran, bean dregs, wheat bran, vegetable cakes, broken leaves of green vegetables, earthworms, fly maggots or fish formula feed, as well as human dung, pig manure and so on. The amount and time of feeding are generally fed once or twice a day, that is, once in the morning and once in the evening, and the daily dosage is generally 4% and 5% of the total weight of Loach. When the water temperature exceeds 30 degrees, the water should be changed frequently, and the depth of the water should be increased to prevent the water contaminated by pesticides from entering the field.

"if Misgurnus anguillicaudatus often swims to the surface to 'breathe' or swim on the surface, it indicates lack of oxygen, new water should be injected, and fertilization and artificial feeding should be stopped. at the same time, in the fields where Loach is raised, soybeans can be planted on the ridge in advance, and bean stalks and bean leaves can be used to cover the gully to protect the Loach from the summer." Li Yunzhong pointed out that the paddy or rice fields where Loach are released should be managed by special personnel, and pesticides with high efficiency and low toxicity should be selected for pest control of rice, which can be applied according to the conventional dosage, and should be applied in deep water with upward nozzles when spraying pesticides.

"in southern Sichuan, raising Misgurnus anguillicaudatus in rice fields is the most vulnerable to air bubble disease and parasitic diseases. For the prevention and control of air bubble diseases, 4 kg ~ 6 kg of salt per mu can be sprinkled with water throughout the field; for the prevention and control of parasitic diseases, 0.7ppm copper sulfate or 0.5ppm crystal trichlorfon can be sprinkled in the rice fields." Li Yunzhong also introduced that it is appropriate for Loach to catch Misgurnus anguillicaudatus in late autumn and early winter. Sun-dried rape branches and stalks can be used when fishing, immersed in the field side ditch, waiting for rape branches and stalks to escape sweet taste, the whole field Loach will smell and absorb sweet water, at this time, the ridge can be caught by hand to copy the net, and a large number of fish can be harvested, and the Loach submerged into the mud can be caught by turning the mud.

According to the experts of Naxi District Water Bureau, raising Loach in rice field is a three-dimensional production mode of comprehensive utilization of rice field. Because of the abundant natural bait in the paddy field, Loach can loosen the field mud, improve the soil and prey on pests, which is not only beneficial to the growth of rice, but also reduce the harm of pests. Therefore, raising Loach in rice field is a "win-win" project of "Loach strong and rice fragrant". Secondly, the technical difficulty of raising Loach in rice field is not very difficult, the Loach raised is not only ecological, environmental protection, but also green machine food. And ecological Loach in the market has a wide market, market supply and demand is large, the price is also high, favored by the majority of consumers. It is hoped that after understanding this simple applicable technology, the broad masses of farmers might as well immediately move and take action to make full use of the rich rice field resources in rural areas and jointly become rich and well-off.
