Device with pollen taking, pollination and sprinkling irrigation functions and pollen taking, pollination and sprinkling irrigation method thereof

The invention discloses a device with pollen taking, pollination and spray irrigation functions and a pollen taking, pollination and spray irrigation method thereof. An electric turnover valve in a spray head is used for switching water flow to one end of a water spray end plate of the spray head, or compressed air flows to one end of an air spray end plate of the spray head; when water or compressed air is sprayed out from the spray head, the spray irrigation and pollination rotating wheel mechanism can rotate, and a layer of fluff is arranged on the circumferential surface of a circular disc of the spray irrigation and pollination rotating wheel mechanism; when pollen is taken, the circular disc rotates, the pollen can be taken from the fluff on the circumferential surface of the circular disc, and the pollen taking efficiency is higher; during pollination, the circular disc rotates, pollen can be scattered in the air, the pollination range is wide, and the pollination efficiency is higher; during sprinklin
