Replacement of bee queens and poor bees spawn fewer births, high winter mortality rates, and short duration of spawning peaks in the spring of next year. Therefore, a group of excellent new queen bees must be cultivated in the fall. The replaced queen can form a double king bee and allow it to continue spawning until it is discontinued. It is the best wintering population for cultivating the bees that were raised from the white-exposed eggs (ie, white dew) produced by the age-old overwintering bees. Feeding overwintering feeds is usually performed after the wintering seeds are produced. The ratio of sugar to water is preferably 1:0.6. Focus on feeding within 2-3 days. To prevent the theft of bees during the autumn honey source, the bee colony should be easy to dispose. At this time, the bees should be released and an empty box should be used to collect the old bees. When serious, the bees should be transferred. Active treatment is generally performed in two stages. The first time before the cultivation of the age-appropriate bees, the second time in the colony, the wintering and natural incisions are entered. Bees should be fed before medication. Timely breaks were made after bee colonies cultivated overwintering bees. Increase the bee colony (15-20 mm), extract pollen spleen from bee colonies, withdraw the insulation, use honey to take up a large number of nests, force the queen to break early, and colonize the bees early. The queen bee can also be closed, prompting him to stop giving birth.
