"White jade snail" is easier to breed successfully, but according to different seasons, carefully adjusting the breeding environment is still the key to achieve high yield and high efficiency. In the vast areas of China, the artificial breeding of this snail species in summer should pay attention to the following issues: 1. Ventilation and cooling The temperature in the north and south of China during the summer is generally high. The maximum temperature during the day is more than 30°C, and the highest is 35-40°C. The optimum temperature for growth of white snails is 25-28 °C, and the temperature difference between day and night should not exceed 5 °C. If the temperature is too high, it will lead to hibernation. If the temperature is too low, the snail will stop feeding. Therefore, it is an important task for summer snails to adopt flexible cooling measures. General household farming can use the ventilation method of the morning and night to cool the breeding room. The specific approach is: when the temperature in the breeding room reaches 30 °C or more, and according to the weather forecast, the weather is maintained in the hot days in the next few days. The doors and windows are opened every morning or evening to reduce the indoor temperature by air convection. The time is generally about 30 minutes when the temperature When the temperature drops to about 26°C, ventilation can be stopped. In case of special high-temperature weather, the number of ventilations and daily ventilation time should be appropriately increased. If the outside temperature is low during continuous rainy weather, there is no need for ventilation. 2, spray water temperature adjustment in summer "ventilation" often lead to a decline in the air humidity in the breeding room, so usually every time the "ventilation" with a sprayer to the wall and the surface of the water, spray 1-2 times a day to make indoor air The relative humidity is maintained at 85-90% and the culturing soil moisture is maintained at 40%. During the cultivation period, it is necessary to observe the activity of the snail constantly. If the milky shell is found to be too low, the humidity is too high; when the screw shell is wet and wet, it indicates that the humidity is high; when the mucus film is found in the screw mouth, it may be due to lack of water in the feeding; The snails clustered on the wall of the pool and did not peck at night to show that the feeding soil was too wet. 3, pay more attention to the quality of feed 1 summer high temperature, high humidity, wheat, corn flour and other nutrient-rich concentrates are easily mildew, where moldy feed must not be used to feed snails. Therefore, in the summer snail concentrate must be stored in a dry and ventilated room and pay attention to inspection. If you use with concentrated feed, it is best to use the current amount of daily use. 2 During the summer, crop pests and diseases occur frequently. Vegetables and forages grown on snails should not be used for chemical pesticides. If necessary, biological pesticides or physical methods can be used to prevent pests and diseases. Each time the harvested forages and vegetables are washed with clean water before feeding, they are allowed to feed. In addition, there should be plans to harvest feed and avoid feeding green feed every other day. Finally, to remind the majority of introducers, the summer season of high-temperature farming season, the labor force is tense, but this period is also in the key period of snail growth and development and produce a "golden period" of benefits. Under such circumstances, we must not relax the careful management of snails. Only in this way can we obtain the desired benefits.
