Description

(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ СВЕТОВОГО РЕЖИМА В ПОСЕВАХ РАСТЕНИЙ(54) DEVICE FOR CONTROL OF LIGHT MODE IN CROP PLANTS

Изобретение относитс  к устройст-вам дл  контрол  светового режима растительных посевов в полевых и лабораторных услови х. При этом особо важное значение приобретает контроль средней сферической облученности растений при разных угловых направлени х светоисточника. Известно фотометрическое устройство , содержащее фотометрическую головку , световод и регистрирующий прибор . Недостатком этого устройства  вл етс  возможность только проводить измерение пр мой облученности, что, естественно, вызывает значительную погрешность чувствительности устройства при угловых расположени х источника облучени  или Солнца tU. Целью изобретени   вл етс  измерение средней сферической облученности при сохранении посто нной угловой чувствительности по всем контролируемый направлени м. Цель достигаетс  тем, что светоприемник фотометра выполнен в виде ци линдра, верхний торец которого закрыт непрозрачным диском, а бокова  поверхность охвачена юстировочными кольцами, одно из которых имеет кони. ческую внутреннюю светоотражающую поверхность , На фиг. 1 показана схема устройства; на фиг. 2 - юстировочные кольца; на фиг. 3 - график результатов испытани  устройства. Устройство состоит из световоспринимающего элемента 1, имеющего форму цилиндра из еветопропускающего глушенооптического материала, например , стекла типа МС 13; жесткого световода 2, фотоэлектронного приемника излучени  3, измерител  фототока 4, юстировочного кольца 5 с зеркальной конической поверхностью 6, непрозрачного диска 7. Юстировочные кольца 5 выполнены из раздвижных частей 8 и 9, которые могут перемещатьс  относительно друг друга вдоль образующих цилиндра. Отношение диаметра световоспринимающего элемента 1 к его высоте составл ет 0,8-1,3. Внешний диаметр кольца относитс  к диаметру цилиндра как 1,2:1,5. Высота А кольца (фиг. 2) составл ет 15 -35% высоты цилиндра.Изменение размера А достигаетс  перемещением части 8 кольца относительно часThe invention relates to devices for controlling the light regime of plant crops under field and laboratory conditions. At the same time, control of the average spherical irradiance of plants at different angular directions of the light source is of particular importance. A photometric device is known comprising a photometric head, a light guide and a recording device. A disadvantage of this device is the ability to only measure direct irradiation, which naturally causes a significant error in the sensitivity of the device when the angular location of the irradiation source or the Sun tU. The aim of the invention is to measure the average spherical irradiance while maintaining a constant angular sensitivity in all controlled directions. The goal is achieved by the fact that the photometer's light detector is made in the form of a cylinder, the upper end of which is covered by an opaque disk, and the side surface is covered by adjusting rings, one of which has horses. internal reflective surface, FIG. 1 shows a diagram of the device; in fig. 2 - adjusting rings; in fig. 3 is a graph of device test results. The device consists of a light-perceiving element 1, having the form of a cylinder made of an anti-transmission suppressor-optical material, for example, glass of type MS 13; a hard light guide 2, a photoelectronic radiation detector 3, a photocurrent meter 4, an adjustment ring 5 with a mirrored conical surface 6, an opaque disk 7. The adjustment rings 5 are made of sliding parts 8 and 9 that can move relative to each other along the generators of the cylinder. The ratio of the diameter of the light-receiving element 1 to its height is 0.8-1.3. The outer diameter of the ring refers to a cylinder diameter of 1.2: 1.5. The height A of the ring (Fig. 2) is 15 -35% of the height of the cylinder. The change in size A is achieved by moving part 8 of the ring relative to the hour.
