The bee farm is managed skillfully.

Spring beehives should be located in dry, sunny, leeward places, not in open fields, because the cold wind blows, the temperature in the nest spreads, which is disadvantageous to reproduction, and forces @ 255cm to generate heat and consume a lot of stored honey. Dense colony hot early spring reproduction should maintain the proportion of bees and spleen, promote spawning, with the gradual increase in temperature, the development of population potential, can be appropriately relaxed to warm climate, bee colony growth, each frame should also maintain 6 adult bees. The clamp feeding separates the two weak or medium groups with a gate and keeps them together in a box, leaving each nest door in and out. In this way, we can lean on each other to keep warm. The largest egg circle must appear on both sides of the gate, and the two groups of egg circles form a unified whole, which is much faster than that of a single group. When using horizontal nest box, it can also be raised by multi-group clamping box, which is easy to operate in combination and adjustment. Heat preservation and moisture prevention in early spring is more important than heat preservation during overwintering and egg suspension. The honeycomb ventilation of the Chinese bee is ventilated by the fan, so under the box wall and sub-cover, water droplets are often condensed, which is very damp, which makes the thermal insulation materials in the box damp and easy to dissipate heat. Therefore, the thermal insulation materials in the box should be replaced in time, such as to avoid this kind of trouble, it is appropriate to raise strong groups, or multi-group box joint protection, reduce the space in the nest, use bee road wood strips to prevent heat dissipation at the top of the nest. Adjusting the temperature difference between day and night of the nest door in spring is of great significance in heat preservation. The nest door is gradually enlarged in the morning and shrank gradually after 3 o'clock in the afternoon. In order to fill the gap of the beehive for heat preservation, the nest box with screen window is provided, and the gap of the screen window is filled and closed with paper. Remove the packaging in March, gradually remove the thermal insulation materials according to the climate and the degree of bee colony development, first withdraw the top, then withdraw around, and finally remove the bottom of the box; first withdraw the strong group, then withdraw the weak group. It is better to withdraw late than early, and the thermal insulation materials in the box will be gradually withdrawn with the expansion of the honeycomb.
