MEASUREMENT METHOD OF INFLUENCE OF SUN EXPOSURE ANGLE ON PRODUCTIVITY OF LAWN GRASS Russian patent published in 2014 - IPC A01G23/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to arrangement of lawns in city streets. A measurement method of influence of sun exposure angle on productivity of lawn grass involves separation of a section with test grass cover; then, in the same section, groups of trial areas are marked; while marking, distance between centres of the trial areas is considered, and after cutting the grass samples are subject to tests and as per test results laws of influence of distances on grass sample parameters are detected. Either visually or on the map grass lawn sections are separated, trial areas for grass sample cutting are prepared in them; at arbitrary location of streets, number of all trial areas is equal to at least five in the sections, at least three with sun beam illumination at different angles in horizontal plane; with that, sun exposure angle of a trial area is calculated as equal to a total angle from sunrise to sunset on measurement day with subtraction of all shadow angles from buildings and trees.

EFFECT: invention allows improving functional capabilities of the method in trial lawn areas and other places, where shadowing from buildings and trees occurs, and therefore, a sun exposure angle of grass plants in trial areas is formed.
