The invention discloses a target layout device and method for photogrammetry on the top of a historic building. The device comprises an overhanging pipe, an exhausting pipe in the overhanging pipe is communicated with a sucking pump through an exhaust hole, a sucking disc communicated with the exhausting pipe is installed at the front end of the overhanging pipe, and a target for photogrammetry is adsorbed on the sucking disc; a touch type switch is installed at outer side of the front end of the overhanging pipe simultaneously, and a telescopic trigger rod in the touch type switch is parallel to the overhanging pipe and extends to the outer side of the sucking disc. The target layout method comprises the following steps: firstly, installing the overhanging pipe on an unmanned aerial vehicle through an installing frame, and communicating the exhaust hole at the root of the exhausting pipe with the sucking pump on the unmanned aerial vehicle; adhering the frontage of the target to the sucking disc, switching on a power source of the sucking pump so as to fix the target on the sucking disc, and uncovering a sticker on a sponge double-faced adhesive tape on the back of the target to expose a viscous surface; and enabling the unmanned aerial vehicle to take off to gradually approach to a correct position on the historic building and adhering the target to the building, and repeating the process until the layout of multiple and various targets is finished.

The invention relates to a pollination isolation screen for apricot trees. The pollination isolation screen comprises a plurality of supporting rods, a fan, an anther storage box, a liquid storage box, a control display device, a plurality of screen meshes and a door, wherein foot columns are arranged at the lower parts of the supporting rods; two buttons are arranged on each supporting rod; the fan is supported at the top of the screen through an electric wire pipeline; the anther storage box is provided with an anther output pipe a and an anther output pipe b; a shower nozzle a is arranged at the other end of the anther output pipe a; a shower nozzle b is arranged at the other end of the anther output pipe b; the liquid storage box is provided with a liquid output pipe; a fine water mist nozzle is arranged at the other end of the liquid output pipe; the control display device is provided with a plurality of display interfaces and buttons. According to the pollination isolation screen for the apricot trees, provided by the invention, the height of the screen can be adjusted according to the height of the apricot trees; meanwhile, the humidity and temperature in the screen are adjusted and the environment in the screen is controlled, so that a growth environment which is more suitable for the apricot trees is formed and the fruiting quality of the apricot trees is improved; the pollination isolation screen is more convenient to use and has a wider application range.
