Document Type and Number:
WIPO Patent Application WO/2021/024583
Kind Code:
A1
Abstract:
Provided is a plant cultivation device wherein the occurrence of tipburn is suppressed. This artificial light-type plant cultivation device 1 is provided with a cultivation chamber 4, the inside of which can be sealed. Within the cultivation chamber 4, the plant cultivation device is provided with: a cultivation room 10 for growing a plant; and an air circulation system 30 for generating an air flow from top to bottom in the cultivation room 10. Since the air circulation system 30 can blow air to a plant V from directly above, air is blown to new leaves growing in a central portion of the plant to promote transpiration. As a result, sufficient calcium can be supplied to the growing leaves and tipburn is less likely to occur.
