Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent agricultural equipment, and particularly relates to a multifunctional precise pollination device. Background Technique

[0002] Pollination is crucial for crop production. Due to factors such as the reduction of pollinating insects, adverse climate effects, and the shielding of greenhouse facilities, it is difficult to ensure the natural pollination rate and pollination quality. To ensure high yields, artificial assisted pollination has received increasing attention. At present, the artificial assisted pollination techniques mainly include dot pollination, powder spraying pollination, and liquid spraying pollination, etc. Dot pollination has the risk of hormone residues and has been gradually phased out. Powder spraying pollination relies on manual operation, with a very high labor intensity and has not been promoted and applied. Liquid spraying pollination is carried out with the help of plant protection machinery such as electric sprayers and plant protection drones, and has the advantages of high operation efficiency and low labor intensity, and has developed rapidly in recent years. However, liquid spraying pollination requires a lot of time to prepare the pollen solution in advance, and the pollen solution must be sprayed within a short time, otherwise the pollen will germinate prematurely under high temperature. In addition, there is currently a lack of special liquid pollination equipment, and rotating machinery such as water pumps and centrifugal nozzles commonly used in plant protection machinery will damage pollen grains.
