Why are hives with bees placed in the gardens during the flowering of fruit trees?

This mainly applies to very large orchards where fruits are grown for sale and distribution. This also applies not only to gardens, but also to flowering fields. For example – during the flowering of buckwheat hives are placed there. This is necessary for two reasons. The bees pollinate the flowers and this makes the further development of the fruit possible. In large fields and gardens, beehives are essential for the harvest. The second reason is getting honey. This is how a certain type of honey is obtained, when bees use flowers of only one type of plant to extract nectar.
