American frogs are smaller than bullfrogs, have a slightly sharper head, and are more easily domesticated than bullfrogs. They have wide adaptability, well-developed limbs, tame temperament, strong disease resistance, easy management, and easy feeding. As there are more insect pests in the fields, aquatic organisms are abundant, and they are suitable for the life and growth of frogs. The advantage of raising frogs in Putian is that they do not occupy farmland and do not consume much water. Moreover, frogs can cure pests in Putian and save pesticides. (a) Putian choice. Putian selection should avoid alpine clips, require sufficient water, good water quality, convenient drainage and irrigation, water retention is good, the size of the area can be. (b) Construction of Putian. Ask the field to be strong and have a slope so that the frog can climb up to the field to shine. Digging protection trenches 60cm deep and 1-1.5m wide in Putian to provide a refuge and feed site for frogs and fish during water shortage. (c) Putian facilities. (1) There are anti-escape walls around Putian, which can be made of plastic net cloth, bamboo rafts, barbed wire, asbestos tiles, clay and bricks to a height of 1 meter. For example, plastic mesh, bamboo rafts, barbed wire, and asbestos tiles should be buried underground. -15 cm. Intake and drain openings are covered with a sand net to prevent frogs, cockroaches and fish from escaping. (d) Putian disinfection. After the construction of Putian, the water depth is 10 cm, and 50--100 kilograms of water is used for quicklime every 0.067 hectares, which is stirred with hot water and splashed in the whole pool. The second day, the iron is used again to fully decompose the quicklime and kill bacteria. It also improved water quality and sediment quality. After 1 week change the water, cast frogs to put the fry. Or use bleaching powder, 7 grams per cubic meter of water, use tub water, Quanchiposa, change the water after 5 days, vote frog put fry. (e) seedlings. About half a month after planting, 2000--3000 larvae of 40--50 grams per 0.067 hectare were stocked. The disease-free and healthy young frogs are required to have the same individual specifications, so as to avoid the big frogs to eat the small frogs, and at the same time, they can also raise a small amount of grass carp, pupa, cockroach and cockroach. (f) feeding and management. (1) The suitable water temperature for frog growth and development is 20-25°C. The young frog quickly adapts to the environment after it is put into the field, and it is necessary to feed a small amount of food at this time. Such as small fish, shrimp, or cut into small pieces of pig lung, bovine lung and other animal waste, or floating compound feed, timing, positioning, quantitative sprinkled on the surface of the protective ditch or on the food table. Each feed was fed within 1 hour. With the growth of frogs, the quantification of feeding at different periods is: 5%--10% of the body weight of the frog in the early stage and 10%-15% in the later stage (ie, into a frog). Feed 1 - 2 times a day, 9 - 10 hours in the morning, and 4 - 5 hours in the afternoon, mainly in the afternoon, generally accounting for 60% - 70% of the amount of bait throughout the day, more sunny feeding, less feeding on a cloudy day Rainy days do not feed. (The table can be used to nail a wooden basket or use a bamboo product to put a screen on the bamboo basket as a feeding bait on the water). For example, if there are 1,000 frogs per 0.067 hectare, insects and aquatic species in the field can satisfy the growth of frogs and fish. It is also possible to feed black frogs in the Sakata plant to attract frogs. (2) The water depth is maintained at 15-35 cm. (3) Disease Prevention: Keep the water clean, replace it once every 7-10 days, change the water every time 1/3--1/2. Frequent cleaning of the food table, removal of residual baits, and drying of food dishes. Regular disinfection with bleach or other disinfectants. (4) Every morning and evening, we must persist in inspecting the fences for damage and strictness so as to prevent frogs from escaping and enemy enemies from entering. If problems are found, repair them promptly. (5) Putian applies sufficient base fertilizer before planting earthworms, and he or she is careful not to apply pesticides or pesticides. Since there are few pests in Putian, after the frogs are put into the fields, they can prey on large numbers of insects, and generally do not need to spray pesticides and chemical fertilizers. (6) Find enemy enemies such as snakes, rats, and birds and drive them out in time.
