The optimum temperature of the wintering room is -4 ~ 4℃. Too high or too low room temperature will increase feed consumption. When the room temperature rises, you can open the ventilation window in the wintering room to increase the ventilation, or place an exhaust fan to increase the ventilation and expand the honeycomb door. Throughout the winter, the indoor temperature should be cold, not hot. The ventilation holes in the wintering room should be protected from light to ensure indoor darkness.
Overwintering indoors in the south is likely to lead to high room temperature, which should also be controlled below 6℃. Close the doors and windows during the day to keep it dark and open the ventilation at night. If the weather is sultry, the room temperature rises and bees disturb the people, use an electric fan to cool the bees. The temperature in the northern region is low in winter, and the room temperature is easily kept at -4 ~ 4℃. When the room temperature drops, reduce ventilation, narrow the nest door and close the transom. The temperature is high in early winter and late winter, and the room temperature fluctuates greatly. Attention should be paid to ventilation to adjust the temperature of the wintering room.
The relative humidity in the wintering room should be kept between 75% and 85%. Too dry or too wet in the wintering room is not conducive to the safe wintering of bees. If the humidity is too high, the uncovered honey spleen will absorb water and deteriorate, affecting the health of bees. Too dry winter rooms are also harmful to bees. Dry air can absorb the moisture in honey, promote the crystallization of honey, and make bees feel thirsty, eat too much honey, resulting in an increase in feces in the hind intestines of bees. If the wintering room is dry, you can hang soaked sacks indoors, or sprinkle water on the ground, close the air outlet and open the air inlet. When the humidity is high and the room temperature is high, the air inlet should be closed, the air outlet should be opened, and even an exhaust fan should be installed to exhaust moisture.
Observe bees frequently in the first few days. When the room temperature is relatively stable, you can check the bees every 10 day. At the end of winter, the room temperature is easy to rise, and the bee colony should be observed every 2 ~ 3 days. Take timely measures against abnormal bees. Especially in the late wintering period, the wintering room should be light-tight, control the indoor temperature and humidity, and pay attention to the sound of bees. In a dark room, if bees fly out of the hive and the room temperature is not too high, it may be too dry. If the bees are disturbed, the balls are scattered, the bees are listless, and there is quite a lot of honey in the nest. This is the phenomenon that the bees are short of water, so they should be fed with water in time. I found many dead bees on the bottom of the box and the door panel of the nest. The body is intact, the tongue is sticking out, and the honey bag does not store honey. When listening, the noise of bees is weak, and the response to knocking on the hive is small. This is a sign that bees are hungry. It is necessary to rescue and feed them immediately. The best supplementary feeding method is to directly add preheated semi-sealed honey spleen.
