Abstract

Устройство для определения потребности растений в минеральных элементах питания, содержащее несколько измерительных каналов, каждый из которых включает в себя измерительную кювету, источник засветки, оптический приемник на длину волны 620 нм и электронный блок обработки информации, отличающееся тем, что источник засветки устанавливают в нижней части кюветы по ее оси, а два оптических узкополосных приемника с максимумами светочувствительности на длинах волн 620 нм и 460 нм соответственно располагают с противоположных сторон измерительной кюветы перпендикулярно оси излучения источника засветки, при этом выходы оптических приемников подключают к блоку формирования разностного сигнала.A device for determining the needs of plants in mineral batteries containing several measuring channels, each of which includes a measuring cell, a light source, an optical receiver at a wavelength of 620 nm and an electronic information processing unit, characterized in that the light source is installed in the lower part cuvettes along its axis, and two optical narrow-band receivers with maximum photosensitivity at wavelengths of 620 nm and 460 nm, respectively, are located on opposite sides of the measuring cuvettes perpendicular to the axis of radiation of the illumination source, while the outputs of the optical receivers are connected to the differential signal generation unit.
