Abstract:  Apiculture, as one of the key industries supported by China to help revitalize the countryside, has entered a period of steady development, and nectar and pollen source plant planting that goes with it also needs to be given sufficient attention. Nectar and pollen are the food sources of bees, which directly determine the nutritional structure of bee colonies, and pollen source plants provide nectar and pollen for bees, which are the material basis for the survival and growth of bee colonies. A single pollen source crop leads to the problems of a single nutritional structure of bees, bee colonies being forced to collect toxic pollen source plants, and the development of the bee industry being subject to the influence of the seasons with great fluctuations. Planting diversified nectar and pollen source plants enriches the biodiversity, which is a supplement to intensive agriculture monocrops, and bees can obtain a balanced diet, ensure the yield of bee products, and provide habitats for wild pollinating insects and natural enemies of pests, further improve the pollination link of crops, reduce the use of pesticides, and promote the healthy development of the bee industry and agriculture. The planting of nectar and pollen source plants requires scientific guidance, adequate investigation of local nectar and pollen sources and environmental conditions, and the selection of suitable plant species and planting modes according to local conditions. The promotion of nectar and pollen source plant planting requires the full cooperation of the government, enterprises and research institutes. In view of the significance of nectar and pollen plants in safeguarding the health of bees and maintaining ecological balance, we scientifically analyzed the impact of nectar and pollen source plants on bees and the significance of the planting of nectar and pollen source plants on beekeeping and rural revitalization, explored the relationship between the planting of nectar and pollen source plants and sustainable development of the beekeeping industry, and provided some references to the planting of nectar and pollen source plants with recommended measures in this article. It is a valuable guide for research in the field of insects.
