In the Natural Beekeeping, RJ is manufactured in single bee forage of rape blossoms. The RJ obtained from rape blossoms is highly active. In particular, the pollen of rape blossoms is active and strengthens the colonies after wintering.

On the other hand, the bee forage is not specified in ordinal beekeeping, and RJ is manufactured even in the absence of bee forage by feeding with sugar water and artificial pollen. The rape blossoms growing in the flat plains of mainland China can no longer be used due to contamination from agrochemicals, and my group has
