METHOD FOR THE RAPID DETERMINATION OF THE VITAL STATE OF WINTER WHEAT CROPS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture. The method for operatively determining the vital state of winter wheat crops includes measuring the electrical resistance of plant tissue, and the electrical resistance of the plant tissue is measured near the tillering node at two frequencies and determines the coefficient of the vital state as the ratio of the electrical resistance of plant tissue measured at a low frequency of 10 Hz or 1000 Hz to the electrical resistance of plant tissue measured at a high frequency of 500 Hz or 10,000 Hz, at a ratio of 1/50 or 1/10, respectively.;EFFECT: invention makes it possible to quickly determine the vital state of winter crops directly in the field.;1 cl, 5 dwg, 1 ex
