Living body holding structure used for measuring growth condition of crops under cultivation

摘要

An object of the present invention is to provide a living body holding structure for use in a growing condition measuring apparatus of a growing crop, capable of continuously measuring the nutrient status of a plant nondestructively with respect to a growing crop at a growth stage before harvesting. SOLUTION: A biological holding structure used in a growing condition measuring apparatus of a crop under cultivation according to the present invention irradiates irradiation light to measurement sites 1a, 1b and 1c of plant 1, and from measurement sites 1a, 1b and 1c. Light from the detected light, and from the detected light received, indicates the nutritional status of the plant 1, the amount of nitrate nitrogen, the amount of carbohydrates, the amount of proteins, the amount of mineral components, the amount of antioxidants, and the amount of water, A biological holding structure used in a growing condition measuring apparatus of a growing crop for calculating an amount of the component, wherein the plant 1 is a growing crop in a growing stage before harvesting, and the measurement sites 1a, 1b, 1c are stems It is characterized in that it is attached to a stem, a stem or a stem, and any one of a stem and a stem.
