When the bees go winter, they must be "ten defenses."
First, heat. The suitable temperature for winter bees is -2 to 8°C. At this time, the bees in the beehive united to live on honey and stay asleep. However, the number of days above 8°C during the entire wintering period is relatively large, the amount of bee activity is large, feed consumption is high, and the worker bees are aging rapidly and are not easy to reproduce, which delays the production period. Heat protection methods can be used for ventilation, watering, or cooling fans. Second, cold. Overwintering bees are also active in temperatures below -2°C. It is mainly to increase the amount of food, keep the belly, rely on activities to generate heat, to resist the cold. This will not only consume a lot of feed, but will also shorten the lifespan of workers. The method of preventing the cold is: small groups of bees should be more sunning during the day and try to close the table at night to fill the box seams and holes. Third, anti-drying. In the dry winter without snow and rain for a long time, it is necessary to prevent the bees from thirsty and dry, and spray water, increase humidity, and prevent thirst from bees in the beeyard. Fourth, prevent moisture. The humidity in the beehive in the winter is the best among 70%-80%, and more than 80% of the feed is easily thinned and deteriorated, and the bee eaters are prone to suffer from big belly disease and pull. If the humidity is high, lay a plastic film under the beehive, or sprinkle lime and dry slag around the beehive. In clear weather above 10°C, bees can be systematically excreted and cooled. Fifth, prevent boredom. Bees can't leave fresh air in the box at all times. To prevent the body and debris from clogging the nest door, suffocate the colony. Snow days, but also to prevent the snow closed the nest door. Sixth, prevent disease. Keep the beehive clean and pay attention to disinfection. Winter mice will eat the bees to destroy the spleen. If mice are found on the apiary, they must use poison baits and equipment to kill them. Seventh, shockproof. Bees like to be quiet and afraid of vibration. Especially in the late winter, the bee is very weak, and it is unbearable to accumulate in the abdomen. If it is shaken, it often dies and freezes. Therefore, it is forbidden to knock violent instruments and firecrackers in the beeyard. Eighth, prevent hunger. Whether the quality of the feed during the whole winter period is sufficient or not is the basis for the success or failure of overwintering. After the bees were eaten, most of the bees were digested, the bee colony was quiet and stable, the longevity was long, the spring was fast, and it did not decay. After the poor quality feed bees eat, there is less digestion, and there are more slags remaining. The feces are not contained in the intestines, and it is easy to form big belly disease, severe diarrhea, partial death of the light, and death of the entire group. High-quality feed should be harvested at the end of autumn when the spleen is extracted. After the honey is flowed, high quality syrup should be fed early to allow the bees to be fully brewed. Nine, anti-light. Bees have phototaxis. If the winter bee field is outdoors, it must be covered and protected from light to minimize flying bees. Ten, anti-feed crystallization. Bees have no teeth and feed crystallized bees are inedible. Anti-crystallization method: First, use high-quality honey as a feed, such as nectar, jujube nectar; second is to use white sugar as feed. When the apiary is too dry, sprinkle water to maintain proper humidity.
