First, do a good job of heat insulation and cold winter day and night temperature difference is larger, the daytime high temperature bee colonies around the box, the evening temperature dropped bee colony contraction. Therefore, special attention should be paid to the warmth of bee colonies at night. When the cold wave comes, the nest door should also be properly reduced.
Second, the science feed supplement winter feed must use mature honey or pure white sugar that does not love to crystallize. Honey containing rust and contaminated with harmful substances cannot be used as winter feed. If honey is used as feed, because the honey produced in the fall contains glucose crystallization nucleus or crystallized, it is necessary to add 50 kg of mature honey to 3 to 4 kg of water before feeding, and gradually put it in a pot to 70 °C for half the duration. Remove it after an hour to fully dissolve the glucose crystallization nucleus; use sugar syrup as feed, that is, add 50 grams of sugar and 28 to 33 kilograms of water, put the water into a pan and warm it up to 100°C, and then add sugar to it. Dissolve and remove the cooling when it reaches 100°C again. Supplementing the overwintering material in a short period of time requires feeding in sufficient quantities for a short period of time. The feeding time must not be extended to prevent the queen bees from spawning, resulting in a high nest temperature and a loose beehive that will affect safe wintering.
Third, timely and appropriate to take the spleen before the beginning of the winter before the frost, the honey source during this period is still relatively adequate, the temperature is also high and stable, suitable for spleen honey. When the nest is stored at more than 80%, spleen can be taken, but 2 to 3 honey spleen should be left in each box to prevent abrupt changes in temperature and spleen deficiency. After the snow is over, shake honey should be careful to do "less shake, many times", if there is no good weather for 3 days, do not take spleen.
4. Prevention of sudden freezing In the beginning of winter, when cold bees begin, cold winds often swell, and it is very easy for the bees to freeze and die outside. Therefore, the bee farm should keep away from the source of the powder and not be greedy and lose money. This will also benefit the bee-keeper.
