Description
Известные способы оценки действи оптического излучени на растени (по интенсивности фотосинтетически активной радиации, по интегральной облученности и др.) сложны и недостаточно точны.The known methods for assessing the effect of optical radiation on plants (by the intensity of photosynthetically active radiation, by integral irradiance, etc.) are complex and not accurate enough.
Предлагаемый способ облучени отличаетс от известных тем, что измер ют ту часть поглощаемой растени ми энергии излучени , котора используетс в растении в процессе фотосинтеза и соответствует спектральной чувствительности среднего растени данного вида.The proposed irradiation method differs from those known in that it measures the part of the radiation energy absorbed by plants that is used in a plant during photosynthesis and corresponds to the spectral sensitivity of the average plant of a given species.
Дл осуи;ествлени способа применен фотоэлектрический фотометр с разлагающей излучение в спектр призмой или дифракционной рещеткой и щелевой диафрагмой, выдел ющей излучение требуемой области спектра.A photoelectric photometer with a prism or diffraction grating and a slit diaphragm emitting radiation of the required spectral region was used to inspect the method.
Сущность предлагаемого способа заключаетс в том, что о вли нии оптического излучени на накопление растени ми органического вещества суд т по той энергии оптического излучени , котора может быть непосредственно использована растени ми в процессе фотосинтеза. Эта часть излучени определ етс предварительно теоретически или экспериментально .The essence of the proposed method is that the effect of optical radiation on the accumulation of organic matter by plants is judged by the optical energy that can be directly used by plants during photosynthesis. This part of the radiation is determined theoretically or experimentally.
Лучистый поток, оцененный по спектральной чувствительности растени , названный фитопотоком, представл ет собой ту часть мощности излучени , котора при наиболее благопри тных услови х может быть эффективно использована растением в процессе фотосинтеза.The radiant flux, estimated by the spectral sensitivity of the plant, called the phytocurrent, is that part of the radiation power that can be effectively used by the plant during photosynthesis under the most favorable conditions.
Избрав в качестве эталонного излучение с длиной волны 680 ммк, за единицу фитопотока принимают фит, чис тенно |равный фитопотоку однородного излучени с длиной волны 680 ммк и мощностью 1 вг.Having selected radiation with a wavelength of 680 microns as a reference, they take a fit for a unit of a phytoflow, which is distinctly equal to a uniform flow of a uniform radiation with a wavelength of 680 mmk and a power of 1 Vg.
Непосредственное измерение фитооблученности можно осуществить прибором - фитофотометром, спектральна чувствительность которого будет соответствовать спектральной чувствительности растени .A direct measurement of phyto-irradiation can be carried out with a phyto-photometer, whose spectral sensitivity will correspond to the spectral sensitivity of the plant.
Принципиальна схема оптической части фитофотометра представлена на чертеже.A schematic diagram of the optical part of the phytophotometer is shown in the drawing.
