Luo Shudong, a researcher at the Institute of Bee Research, Chinese Academy of Agricultural Sciences, told China Science Daily that pears are a rigorously outcross-pollinated fruiting crop, which requires different varieties of pollen to pollinate each other to produce fruit.
In southern Xinjiang and other places, the flowering period of pear trees is very short and often accompanied by sandy weather.
Luo Shudong explained that liquid pollination is the process of dissolving pollen into the liquid, and then spraying the pollen liquid onto the flowers through a spraying device to complete the pollination process.
Since 2018, Luo Shudong’s team has thoroughly analyzed the advantages and disadvantages of several pollination modes.
Coupled with the high-efficiency spraying methods of drones, and supplemented by additives that promote the germination of pollen on the stigma, they constructed a high-efficiency liquid pollination technology system for drones based on bee pollen, forming a bee pollen vitality maintenance technology, bee pollen The main pollination technology system is the vitality protection technology after dissolving in water, the high-efficiency liquid spraying technology of drones and the auxiliary technology of bee pollen stigma germination.
Luo Shudong said that after two years of large-scale trials and demonstrations in three places (Kashgar, Aksu and Korla), the results showed that this set of technical operations is efficient, evenly set fruit, and easy to operate, and the cost is only 1/3 of the cost of artificial pollination.
