The flowering period of rape, which is engaged in bee breeding, is an ideal honey source for early spring bee colony reproduction, because the nectar of rape flower is particularly rich and the flowering period is very long, so it is particularly beneficial for early spring bee colony reproduction.

The basis of high yield of bee colony in rape flowering period is "Good Wang Qiang Colony". It is necessary to follow the objective laws of climate and honey source and carefully manage the bee colony with scientific methods, so that the bee colony can maintain its sustainable development strength throughout the flowering period, thus obtaining higher benefits.
