On April 11, the "Bee-Machine Collaborative Operation Safe and Efficient Liquid Polpollination Technology On-site Exhibition" was held in Korla, Xinjiang Province. At the meeting, experts introduced the pollination technology system of bee-machine cooperation, and demonstrated the pollination operation of unmanned aerial vehicles .

Since 2018, under the support of the Chinese Academy of Agricultural Sciences and the key projects of Xinjiang Production and Construction Corps, researchers of Institute of Apicultural Research have made an in-depth analysis of the advantages and disadvantages of several pollination modes, and selected the liquid pollination technology to obtain pollen as the breakthrough point, and the efficient spraying of unmanned aerial vehicles as the means. With bee pollen vigor maintenance technology, bee pollen vigor protection technology after dissolving in water, UAV high-efficiency liquid spraying technology and auxiliary technology of bee pollen stigma germination as the main body, the UAV high-efficiency liquid pollination technology system based on bee pollen was constructed. Through the large area tests and demonstration recent years, the results show that the fruit-setting rate of bergamot pear inflorescence can reach 81.4%, far exceeding the actual production demand of 30%-40% of the fruit-setting rate of inflorescence, and the yield per mu of fragrant pear will increase by more than 500 kg, and the revenue per mu will increase by more than 2000 RMB.

The activity was strongly supported by Xinjiang Academy of Agricultural Reclamation Sciences, Zhengzhou Fruit Research Institute, Western Agricultural Research Center, Grassland Research Institute, Agriculture Information Institute and the Second Agricultural Division of Xinjiang Production and Construction Corps.
