Efficient technology of breeding toad in paddy field

Toad is a valuable amphibian and reptile of food and medicine. Toad's shell toad clothing and serous bufo bufagi collected and processed by retroauricular gland are valuable traditional Chinese medicine. With the lack of wild resources, artificial breeding is imperative. Using rice fields to raise toads can complement each other's advantages and form a good cycle of the natural food chain. The relevant technical points are briefly described as follows.

The field pool setting chooses the field which is more secluded and convenient for drainage and irrigation. The paddy field is surrounded by a 0.8-meter-high nylon net with a width of 1.5 meters, which is convenient for the toad to get ashore, and a net is set up at the inlet and outlet to prevent the toad from escaping. A small pond is dug only on one side of the ridge of the rice field to raise tadpoles. The pond area is not less than 1 big 6 of the total area. If the aquaculture rice field is too large, several small ponds can be set up, the water depth of the pond is 40 cm, and a water injection pipe with a diameter of 1 cm is set up over the pond, and a water outlet is set up on any side of the ridge, surrounded by polypropylene mesh. The mesh should be 60 per square centimeter.

When tadpoles are released, the small ponds are dry cleaned with 15kg of quicklime, water is injected 7 days later, 100kg of fermented organic fertilizer is added to the pond, and tadpoles are put into the pond 5 days later. Harmless, robust and neat tadpoles are selected for stocking. After 1.5% salt water disinfection, 6000 ~ 8000 tails per mu of rice fields are released, and the temperature is not lower than 20%.

Toad ponds manage small ponds not only to ensure micro-running water, but also to keep the water quality from deteriorating under the action of residual bait. When feeding, it is appropriate to feed a small amount for many times, and feed it with floating powder until it is abnormal. After the abnormal end of the toad, a round bait platform with a wire mesh at the bottom was set up in the middle of the pond, and the live bait (earthworms, maggots, etc.) and floating particles were fed every day, and water was added from the water injection pipe to brake the floating particles during feeding. Toad feeding and domestication. At the beginning, the proportion of live bait was large, and then decreased gradually. after the toad had a fixed feeding habit, the net of the small pond could be opened and the toad could be put into the paddy field to find food freely.

After the field management toad entered the rice field, the field water quality was kept relatively fresh in advance. In the hot summer, the field should often irrigate "horse race water" to adjust the water temperature and water quality. In addition, if a disease occurs in rice, spraying pesticides should choose sunny days, the nozzle is facing up, and the fog flowers should be fine, so as not to sink the medicine as far as possible. Once the drug deposition in the field is too thick, water injection is immediately adjusted. In general, there is no need to apply pesticides because toads have the ability to catch pests. Young toads should prevent their natural enemies such as snakes and eagles in the field. Toads will not get sick under general natural conditions, but we should pay attention to mechanical bruises, resulting in traumatic infection. Therefore, special attention should be paid to the arrest, which can only be caught with a cloth pocket. Two months after the toad was put into the rice field, it was screened once a month to catch the big and stay small, and then placed in a special culture pond for collecting toad clothes, toad venom, or for sale.
