| Abstract [eng] |
The research of spectrophotometrical plant growth diagnostic method to detect plant growth conditions under micronutrient deficiency. The method is aimed to detect deficiency of main chemical elements (Fe, B, Mn, Zn, Cu, Mo) during plant vegetation period. The method and device is based on irradiation of leaves of different age, placed in separate chambers, by ultraviolet, visible and infrared light and spectral analysis of light reflected from leaves. The estimation of micro elements deficiency and plant diagnosis is performed according to measured differences between spectra of a light reflected from all leaves of the plant. |
