DEVICE TO DETERMINE DEPENDENCE OF ENTOMOPHILOUS PLANT SEEDS PRODUCTIVITY ON POLLINATION WITH BEES Russian patent published in 2011 - IPC A01H1/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to devices for detection of dependence and efficiency of artificial pollination of blossoming plants with bees, which influence productivity of crops. A screen to determine dependence of entomophilous plant seeds productivity on pollination with bees includes a frame with stands and with horizontal side screens that limit access to plants. The horizontal screen is arranged as adjustable in height with the help of sliding stands. Side screens mounted along the perimetre of the horizontal web to adjust height of their installation are equipped with additional collapsible or attachable screens, made of the same material, and are fixed on the main side screens with the help of button locks or "sticky" locks mounted along the vertical line. At least one of sides in the frame of the horizontally arranged screen is equipped with at least one mechanism of web tensioning, arranged in the form of a threaded pair - screw-nut. The surface of the screen web is made of transparent water- and air-permeable material, which provides access to plants of all spectrum of sunlight beams and ensuring full-scale photosynthesis of plants, for instance, from gauze or fine mesh.

EFFECT: using the invention will make it possible to produce valid positive results, which may be used to grow various crops pollinated with melliferous bees.
