Problems solved by technology

However, even when the plant receives light and the leaf temperature is high, when water stress occurs due to insufficient water, the plant closes the stomata in order to maintain water, and it cannot absorb carbon dioxide from the stomata, and the speed of photosynthesis is significant. reduce

Abstract

Provided is a carbon dioxide fertilization device capable of controlling the optimum supply of carbon dioxide in accordance with the state of photosynthesis of plants. The carbon dioxide fertilization device (1) determines the state of photosynthesis of the plant (23) based on the temperature difference between the vein portion (34) and the leaf portion (A) of the plant (23) and the time, and based on the temperature and the temperature in the agricultural facility The temperature difference between the leaf temperatures of plants (23) is used to determine the speed of photosynthesis of plants (23), and the speed of photosynthesis of plants (23) is used as an index, based on the state of photosynthesis of plants (23) , to control the amount of carbon dioxide supplied to the agricultural facility where the plants (23) grow.

Description

technical field [0001] The invention relates to a carbon dioxide fertilization device. Specifically, it relates to a carbon dioxide fertilization device for a facility for cultivating plants. Background technique [0002] Conventionally, carbon dioxide has been used as a substrate for photosynthesis in plants, and the rate of photosynthesis is affected by the concentration of carbon dioxide. In the case of insufficient carbon dioxide required for photosynthesis, the speed of photosynthesis will decrease. In the production of agricultural products, carbon dioxide is fertilized to plants to maintain a high concentration of carbon dioxide, increase the speed of photosynthesis, and promote growth, thereby achieving an increase in yield and quality. This situation is called carbon dioxide fertilization. As a carbon dioxide fertilization technique, a carbon dioxide-containing microbubble water supply method capable of supplying sufficient carbon dioxide to the vicinity of plant ...
