摘要

PROBLEM TO BE SOLVED: To provide a method for diagnosing a plant nutritional state for promptly and accurately diagnosing a plant nutritional state, to provide a plant nutritional state diagnostic device, to provide a method for recovering a plant nutritional state for promptly and efficiently recovering a plant nutritional state, and to provide a plant nutritional state recovering device.;SOLUTION: There are provided a method for recovering a plant nutritional state, which includes (a) the process of detecting the bioelectric potential of a plant in contrast frequency and at least one detection frequency, (b) the process of diagnosing the nutritional state of the plant from the bioelectric potential detected in the contrast frequency and the bioelectric potential detected in the detection frequency, and (c) the process of giving stimulation by flash light of frequency ≤44 Hz to recover the nutritional state of the plant when diagnosing that the plant is in a poor nutritional state in the process (b), and a means of giving lacking nutrient, and the plant nutritional state recovering device.;COPYRIGHT: (C)2011,JPO&INPIT
