Stocking density of soil element

The soil element grows by molting, and its shape doubles with each molting, and we calculate its every molting according to its age. The male Tuyuan matured after molting for 9 times, while the mother Tuyuan needed to molt 11 times. The artificial rearing process of soil element involves the utilization rate of area and the convenience of management, and the stocking density should also be different according to the growth needs of different instar worms. The list is as follows: larvae 8-100000, 1-2 instar 50, 000 3 Mel, 5-8 instar 25000, 5-8 instar 12500 9 Mui, 13-year-old 4, 000 Mui 5000 soil elements in different stages, in order to facilitate management We also make a list of the depth of the breeding soil: larvae 5-8 cm, adults 8-12 cm, adults 12-15 cm, belly disease, also known as abdominal distension, gastrointestinal disease.

1. Etiology: the pond is too humid and the feed water content is large, which is caused by the excessive accumulation of water and nutrients in the body after overeating fatty feed.

2. Prevention and treatment: when soft-shelled turtle insects are found to suffer from this disease, the disease and insect pests are immediately selected for treatment, and the following measures are taken: first, to open the doors and windows for ventilation to reduce the humidity of the breeding soil; second, to take out the surface culture soil and replace the new soil; third, to stop feeding green materials and to feed dry materials; fourth, drug treatment, stirring evenly according to the ratio of 4 grams of chloromycete powder and 6 pieces of yeast tablets (grinding powder) per 0.5 kg feed, continuously feeding 34 times.
