How do you keep bees in spring? How to promote reproduction?

Spring is the first breeding season of the honeybee year. Good breeding in spring will make a good start for the whole year's beekeeping production, which is very critical. We must go all out to do a good job in every management work. How do you keep bees in spring? How to promote reproduction?

First, how to raise bees in spring?

1. Timely excretion flight of overwintering bees choose sunny, warm and windless weather with a temperature of more than 10 ℃. Take off the insulation and lid outside the box and warm the hive to promote bees to fly out of the hive, so as to eliminate the feces accumulated in the intestines during the overwintering period, restore their normal metabolic function and prolong their life. If the weather is fine, you can continue to let it be excreted, and then skim off the thermal insulation facilities when the temperature is suitable.

2. Honeycomb heat preservation in early spring the external temperature is much lower than the suitable temperature needed by honeybee larvae, and sometimes it is attacked by cold currents, which is very disadvantageous to honeybee reproduction: many bees engage in warming work, which will lead to an increase in feed consumption. the life span of honeybees is shortened. In order to make the colony reproduce rapidly, heat preservation measures must be taken. Can be combined with open-box inspection in early spring, tidy up the hive, extract the excess empty nest spleen, keep the bee more spleen, and reduce the bee path to 8mm, the small group of 1x 2 spleen bees, double kings raised in the same box to facilitate heat preservation; the rest of the space in the box is filled with insulation, the box is packed with grass, and covered with plastic film, the nest door should be reduced sooner or later, it is not suitable to open the box too frequently to prevent heat loss.

3. Feed supplement

After the bee colony begins to breed insects in spring, the feed consumption increases more than doubled, and it is especially important to supplement pollen when there are no honey and powder sources in the breeding period. Through the experiment, it needs to consume 120~145mg pollen to feed a bee larva, and about 150g pollen is needed to cultivate a frame bee. Therefore, after the inspection, for those bee colonies that lack honey and powder, honey and powder feed should be replenished in time. Honey and pink spleen should be replenished when the external temperature is low, and when the external temperature reaches more than 12 ℃. Then feed honey water (or syrup) and pollen cakes. The honey should be fed within two or three days, and then in order to improve the productivity of the colony, it can be rewarded for feeding until there is an auxiliary source of honey powder. Reward feeding should be suitable for vinegar, prevent the feed from pressing the spleen and shrinking the oval circle, and stop feeding when the cold wave comes.

4. There are more honeybee colonies with splenomegaly than nests, and the first frame spleen should be added when there are 2 canopies and 3 covers on the spleen. Among them, the strong group adds the spleen when the area of the spleen reaches 780% of the total area of the nest spleen, and the weak group adds the spleen when a large number of new bees come out of the room. The second and third frame spleen should be added under the conditions of normal weather, honey source, first flower, equivalent bee spleen, healthy queen, more than 70% of spleen, rising temperature and adequate feed, otherwise spleen can be slowly added. The spleen should be flattened with honey and powder, and the 1~2cm should be flattened with a sharp knife so that the queen bee can lay eggs.

Second, how to promote honeybee reproduction in spring?

1. Seal the box and keep warm

Place a spleen after tightening the spleen in the center of the beehive, a partition on one side of the spleen near the adjacent box, and a partition on the other side, and heat preservation outside the board. On rainy or colder evenings, cover the hive with plastic sheeting, but do not block the hive door. The nest door can be closed in the evening depending on the temperature.

2. Auxiliary feeding

After tightening the spleen, auxiliary feeding was carried out from the bottom of the box every night. Put syrup or honey into the bottom feeder, each group can be fed 350 to 400 milliliters for the first time, depending on the number of bees and the size of the spawning circle, with a small amount of horned honey on the spleen.

3. Shaking bees tighten the spleen

During spring propagation, every two beehives are placed side by side, and on a windless evening, each colony is fed with sugar water (the ratio of sugar to water is 1:1) or honey with water. Two hours later, when the bees gather excitedly and the temperature in the box rises, the bees can shake and tighten the spleen. Leave a spleen in the hive, which can promote the queen bee to lay eggs quickly.
