If the temperature is lower than 12°C, the breeding will be stopped. If the temperature exceeds 35°C, there is a danger of heat death. Therefore, the high temperature season should pay attention to sprinkler cooling, winter attention cover, warming and warmth. During the year, April-May is the growing season.
