Embodiment 1
[0043] The present invention designs the growth space of the forest frog pergola to be >750 cubic meters, and locates it on the side of the forest frog hatching tadpole pool. The tadpoles can be guided ashore and enter the fence after abnormality and tail removal. After they are all ashore, the nylon film is buried deep into the soil for 20 cm to block the rats from digging holes. , Snakes drill holes into the shed to eat frogs. Generally, 200 adult frogs are designed to cover an area of one square meter, the fence area is >300 square meters, and the shed height is >2.5 meters. The land in the shed area is 20 cm higher than the surrounding area. The slope outside the shed discharges water, and deep drainage ditches are opened around it. Open shallow ditches and buried pipes for drainage on the side of the walkway in the shed, and seal the water outlet with nylon yarn.

Embodiment 2
[0048] This embodiment has been implemented in Nanhui, Shanghai. In 2003, there were more than 20 consecutive days of high temperature above 35°C and extreme high temperature of 40°C, and the surface soil temperature was kept at 30°C, which did not exceed the 32°C high temperature index for raising forest frogs in Northeast China. It cost about 10,000 to 20,000 yuan to build such a new shed. Yuan. As of August 1, there were more than 40,000 frogs weighing 12-13 grams in the shed. Intensive breeding sheds are welcomed.
[0049] The trichoderma inoculant of the present invention enters the soil, and the live bacteria in the inoculum expand in the soil, inhibiting soil-borne diseases, protecting Rana from diseases and reducing mortality. Popularization and promotion of new technologies to raise ground frogs in the south, enhance the ecological conditions of the frogs to adapt to the many pathogenic bacteria in the south, adjust the space and help the frogs in a suitable soil en...
