First, cultivate a large number of winter bees of the right age. After the larvae exit the house, the bees that have passed the test flight excretion but have not participated in the collection and nurturing work are the appropriate ageing winter bees. These young bees have the advantages of good wintering performance, long life, and strong ability to feed after winter. In order to ensure the quantity and quality of overwintering, in the local last nectar period, we must remove excess nests in the colony in time to keep the bees and spleen proportionate, and remove the stored honey from the dried spleen so as to expand the oviposition circle and pay attention to the heat preservation. Reward feeding will encourage the queen to lay eggs. Second, reserve adequate and high-quality winter feed. In the last honey nectar in the local area, mature bees and half honey spleen are prepared for the colony. The amount of overwintering feed depends on the strength of the bee colony and the length of the wintering period. Generally, each spleen should have 1.5-2.5 kilograms of mature honey. If necessary, add sugar and water-soluble to feed the bees. Avoid using fermented honey and honey. For winter feed. Third, timely governance breaks. The specific time required for the queen bee to stop spawning is under normal conditions, so that the last larvae can fly and excrete after they leave the house. In order to stop the production of the queen bee, the bee colony can be withdrawn from the honey source site in time, remove the nest insulation, relax the bee, and extract the pollen spleen from the nest. It is also possible to use the king cage to confine the queen bee. After entering the nest, all the spleen is the favorable opportunity to cure it, and use the medicine to cure it several times to lay a good foundation for the control of the disease. Fourth, to prevent theft of bees. When the last honey source of the whole year is over, it is absolutely necessary to prevent the occurrence of the theft of bees until the bees formally enter the overwintering state. Fifth, arrange wintering beehives. Should be able to fly in the bee colony during the day, and sooner or later tend to be in a state of grouping. A weak group with less than two boxes of bees should adopt the dual group in the same winter. When setting up the hive, half of the spleen should be placed on both sides of the partition, and the whole honey spleen should be placed on the outside of the spleen to form a bee hive that can be used for mutual warming. The strong hive can be placed in the middle. . A number of wooden sticks with a thickness of 10-12 mm are placed on the frame beam of the frame to facilitate the movement of the bees. The number of nest spleen used in overwintering bees should not be less, such as 4-6 bees with 5-6 spleen and 6 boxes with 7-8 spleen. China Agricultural Network Editor
