About 70% of flowering plants rely on bees for pollination, and nearly 40% of human food is related to bees. Among them, the solitary bees play the most important role with a great number and pollination ability. Pyupack sets up the main hives in urban green areas to provide excellent nurturing environments for solitary bees, allowing them to pollinate the flowering plants in the city, making plants prosperous and environmental quality improved. In line with the flowering period of greenhouse crops, Pyupack uses vice hives to deliver bee pupae, allowing newborn solitary bees to pollinate crops, solving the problem of non-pollinating insects in greenhouses. After the flowering period is over, the vice hives will be returned to the city. Pyupack is committed to improving the urban environment, supplemented by assisting in the pollination of greenhouses, and also providing excellent nurseries for solitary bees living alone to achieve the vision of mutual prosperity between human and bee.
