Through the technical measures such as fertilizing soil, pruning and shaping, the number of flowers, the number of buds and the weight of thousands of flowers have been increased, and the flowers have been harvested four times a year, effectively increasing the yield of honeysuckle, with a yield of about 4 kg per unit.
