发明名称 Method for determination of uniformity of SEED distribution over area at sowing crops
摘要 Method for determination of uniformity of distribution over area at sowing crops includes use of accounting frame with given dimensions with general accounting area S, calculation of number of plants n in area of accounting frame and determination of evaluation index k characterizing homogeneity of distribution of plants over the area. At accounting frame one fixes transparent film and on film one indicates with points placed of plant placement and with radius r that is determined by formula, with centers in those points one describes circles, takes off film from accounting frame, determines with weighing general mass Мof film within inner contours of accounting frame, one cuts parts of film indicated with circles without taking into account overlap of those with each other and with weighing one determines mass Mkr of those parts, from ratio of mass Mkr to general mass Мof filmone determines coefficient of homogeneity of seed distribution over area at sewing crops.
