SUBSTANCE: method involves dividing bee family at different stages of development into separate groups (1,2,3) of frames with bees; placing frames in three casings of beehive (one stationary and two removable casings); repositioning casings in predetermined time interval, normally 15-16 days. As a result, bees become quickly used to the first and second removable casings, which are introduced by beekeeper at the initial stage of development of bee family, and are ready for active comb building, pollen and nectar yield, growing of brood and activity of female bee. Standard frames are of 470 x 300 mm size. Up to 36 bees are involves into working cycle of honey yield. Stationary casing has width exceeding that of removable casings by 30 mm. Space of 1-10 mm between stationary and removable casings may be adjusted to provide additional ventilation and, besides, bee swarm is excluded. EFFECT: improved thermal climate and keeping conditions in beehive, increased honey yield and simplified construction of beehive. 2 cl, 2 dwg
