Several overwintering methods for breeding frogs

The hibernation of frogs is from November to March of the following year, and the hibernation period is about 100 days. Here are some methods of wintering for breeding frogs.
1, the cave winter. In order to adapt to the burrowing habits of frogs, the pool of soil can be loosened in advance around the frog pool, and a number of caves with a diameter of 10 cm and a depth of 1 m can be dug at the level line of the sunny leewards and kept moist for frogs to hibernate into the caves.
2, diving winter. The frog pond should maintain a water depth of 1-1.5 meters, and the bottom of the pond should be left with about 10 centimeters of silt so that the frogs can dive into the mud for winter.
3, indoor winter. A brick 40-50 cm high is built indoors in the direction of the sun, and about 10 cm of fine sand is placed in the pool. Then a pot of water is placed in the pool. The height of the pot is the same as that of the soil, so that the soil maintains a certain humidity for a long time. Cover with bamboo or reed curtains to prevent escape. When the indoor temperature is lower than 0°C, the pool mouth is covered with a film seal and a 40 watt light bulb is warmed in the pool to ensure safe wintering for the frogs.
4, hot springs winter. Where conditions permit, it is best to use hot spring water to keep frogs safe for winter. Generally, it is advisable to build a wintering pond on the spot near the exit of the hot springs, with 60-150 square meters and a water depth of 1-1.5 meters. It is advisable to use bamboo fences or plastic nets as anti-escape facilities. Ingress and egress gates should be provided with anti-escape fences.
5, pots and wintering. Use two pots of the same size. Put one of the wet soils below. Place the frogs. Place the other on top. Then dig a 50- to 60-cm hole and bury the two covered pots. Wintering.
6, cylinders, tanks over the winter. The cylinders and tanks are first loaded with some mud, put a little water, so that the soil at high altitude is moist, there is a small amount of water in the low-lying areas, covered with water plants, straw, and other insulation materials are covered around the cylinders and cans. Keep warm with plastic film. It is also possible to pour boiling water in plastic buckets and raise the temperature in the tanks and tanks. The wintering effect with this method is very good, but only a few frogs can be solved for winter.
7, covered grass winter. At the beginning of hibernation, some aquatic plants, such as water peanuts, should be placed in the pool, which accounts for about 60% of the surface of the frog pool, or 30 cm of rice straw placed in the pool to prevent frost and ensure that the frogs are overwintering.
8. Haystacks are wintering. In the direction of the frog frogs, stack a haystack in the direction of the leeward, or spread loose soil 50-60 centimeters thick, stack the grass above, keep it moist, and then cover with a layer of plastic film. When the temperature drops, the frog will drill into the haystack and hibernate.
9, greenhouses winter. In the frog pool 30cm above the water surface, with bamboo or steel arched or herringbone scaffolding, covered with plastic film seal, it is best to cover a layer of net rope, wind blown through the film, so that the pool temperature is not low At 10 °C, make sure the bullfrogs are wintering. When the temperature rises, it is necessary to properly remove the membrane and ventilate it so as to prevent the bullfrog from suffocating and starving.
