What is the model of cultivating one-year-old fish species in Guangdong and Guangxi
The way of cultivating one-year-old fish species in Guangdong and Guangdong is different from that in Jiangsu and Zhejiang. Instead of multi-species mixed culture at the beginning, monoculture was carried out in the early stage, and after the fish grew to 5-6 cm, mixed culture was carried out in proportion. The advantages of this way of cultivating one-year-old fish species in Liangguang are as follows: (1) the survival rate of fish cultured alone in the early stage is relatively high, usually 80% to 90%. (2) in the later stage, we can "get rid of the inferior and take the best" when matching and stocking in proportion. Mixed culture of strong fish can also improve the survival rate accordingly.

How many times should the rabbit farm be disinfected?
The disinfection theory in the book is,"Twice a week in summer, once a week in the rest of the season." I think this disinfection is done too many times. The purpose of disinfection is to kill harmful bacteria. My practice is once every half month in summer and once a month in the rest of the time. If frequent disinfection is carried out, the aim is to kill harmful bacteria, and the result is to kill all beneficial bacteria. Also, we turned around and left the rabbit house with the sprayer on our backs after disinfection. After disinfection, the rabbits were reluctant to "take drugs" in the cage, which was likely to have side effects. It is known that
