How to replenish and regulate the spleen in spring propagation of Chinese bees.

In spring, the temperature is low and unstable. In order to keep warm, the egg ring is often concentrated at one end of the nest and spleen, and the spawning area is not large. When the climate is warm enough for worker bees to crawl all over the nest spleen, the middle nest spleen should be switched back and forth to expand the egg circle. When the sub-spleen accounts for about half of the area of the nest spleen, empty spleen is added between the outer side of the sub-spleen and the lateral spleen in turn to make the queen bee lay eggs.

3 ~ 4 weeks after the egg circle is enlarged, new bees leave the house one after another to replace the old ones. When the temperature gets warmer and the bee colony enters a rapid development stage, empty spleen can be directly added to the center of the bee colony to let the queen bee lay eggs.
