DECISION METHOD FOR FERTILIZATION AMOUNT

摘要

PROBLEM TO BE SOLVED: To obtain a decision method in which whether a fertilization amount is proper or not can be decided with good accuracy. SOLUTION: In this decision method for a fertilization amount, whether the amount of a fertilizer executed to a sample is within a prescribed range or not is decided. A step wherein the sample to which the fertilizer is executed is irradiated with excitation light is provided. A step wherein delay fluorescence generated from the sample which is irradiated with the excitation light is detected for a prescribed time is provided. A step (S 101) and a step (S 102) which calculated attenuation data as the relationship between the detection time of the delay fluorescence and the luminous intensity of the delay fluorescence are provided. A step (S 103) which finds the decision amount of the fertilization amount on the basis of the attenuation data is provided. In addition, a step (S 104) and a step (S 105) which decide whether the decision value of the fertilization amount is within a predetermined range or not are provided.
