Winter warm shed bee points

Many beekeepers put bees in the greenhouse during the winter, and bees pollinating greenhouse fruit trees can greatly increase the fruit setting rate, making the fruit fruit more fruity. However, the pollination of honeybees has also failed. Sometimes the flowers are already open, the bees do not come out of the nest and they do not even come out in two or three days, and only a few come out, making the pollination fail. There are many reasons why honeybees don't love to go out of the nest. It's mainly about temperature. The minimum operating temperature for bees is 14°C. Sometimes the temperature in the shed has exceeded 14°C, and the bees still do not love to come out of the nest because of the large temperature difference between day and night in the shed. Some greenhouses do not have good insulation, and they fall below 5°C at night and even drop to 0°C. At this time, bees have formed a nesting state in their nests. Even though the temperature rises above 14°C on the second day, the bees are slow and still inactive. . To solve this problem, try to keep the temperature inside the shed at 8°C or more overnight so that the bees can come out of the nest in the morning. The beehive management strengthens the nest insulation, and if it encounters a shed with a large temperature difference between day and night, it tries to raise the nest temperature. The method is: After entering the night, prepare a bottle of hot water, place it in the corner of the space inside the beehive, and separate it with a partition so that the temperature inside the nest will rise. Take it out the next morning and put it back in the evening so that the bees will not be living at night. Bees still do not love to go out of nest. Another reason may be that the bee colony itself has problems. First, the amount of bee colonies is small, less than two boxes, of course, very few out; Second, there are fewer age-appropriate bees and more pediatric bees. The method of remedy is to propose a box or two of bees from a large group of borders and place them directly on the border of the frame with less than two frames of the bees, then quickly add the insulation, cover the lid, and put it in the greenhouse. This method can also be used for bee colonies with many hornets. Before entering the shed, the bee's pre-warm winter bee hibernates. It is impossible for the bees to work out immediately. It must be warmed up. The method is: put the empty spleen in the nest, pull out the dead bees from the bottom of the nest, add insulation, fix the spleen, and then move to the room temperature above 30 °C, and the preheating time can be 20 hours. Listening to the buzz inside the box means that the bee has regained consciousness. In the evening, they were sent to the greenhouse, and they would open the nest door until dark. The next day before the bees did not come out of the nest, cover the front foot of the beehive outside the shed, cover a long straw curtain with a length of 10 meters and a height of 0.66 meters so as to cover the light as much as possible to prevent the bees from collapsing before the end of the collapse. The foot cannot go back to the nest. When the beekeepers enter the sheds in time, some of the beekeepers move the beehives into the shed to preheat them before the flowers are opened. This is wrong. Because the flower is not open, it is not attractive to the bees and the space in the greenhouse is too small. The pre-warming bee colony outside the shed can be avoided if the fruit trees bloom and then moved into the greenhouse. In order to preserve the strength of the bees after they have been out of the shed, it is important to cultivate the spleen, so they must be rewarded for keeping. If the temperature is low at night, you must feed warm sugar water. If the fruit trees are plums, big cherries, etc., be sure to feed pollen, so as to maintain the expansion of the sub-groups and provide labor for pollination in the next shed. The number of bees in the shed is 30 to 50 meters. The sheds use 3 boxes of bees; 60 to 80 meters of sheds use 4 boxes of bees; 100 meters of greenhouses are best to use 2 boxes of bees 3 boxes.
