Provided are: a plant cultivation method for improving the crop acreage of plants that are cultivated indoors, a plant cultivation system, and a rack that is comprised in the plant cultivation system. The plant cultivation method of the present invention comprises: setting a cultivation vesselfor cultivating a plant P in a rack; adjacently arranging a plurality of the rackson a travel line in order of growth of the plant P; intermittently advancing the rackaccording to a growth state of the plant P; and separating the first rackfrom the following rack(s), and making a new rackadjacent to the last rackof the following rack(s)

Plant cultivation method, plant cultivation system, and rack

A greenhouse framework () is assembled out of a framework material () such as typical pipes and the like, and the outer periphery of the greenhouse framework () is covered by a sheet outer surface member () formed from a plastic sheet; a sheet inner surface member () is formed on the inner side of the greenhouse framework () in a manner of being spaced by intervals to a certain extent from the sheet outer surface member () by using a heat shield sheet such that all of a floor surface (), a wall surface (), and a ceiling surface () are substantially in a sealed state; and an air conditioning device () is installed. Thus, a desirable thermal insulation property is achieved between the inside of the greenhouse and the outside of the greenhouse, and air conditioning can be implemented with high energy efficiency. In other words, a greenhouse for plant cultivation that has a simple configuration and can be air conditioned with high energy efficiency can be provided.
