SYSTEM AND METHOD FOR GROWING A PLANT IN AN AT LEAST PARTLY CONDITIONED ENVIRONMENT

摘要

A system for growing a plant (1) in an at least partly conditioned environment includes a cultivation base (11) for receiving a culture substrate (3) with a root system (4) of the plant therein. Root temperature control elements (12) are provided which are able and adapted to impose a predetermined root temperature on the root system, and lighting elements (20,21,22) which are able and adapted to expose leaves of the plant to actinic artificial light. Leaf heating elements are also provided, which are able and adapted to impose on the leaf of the plant a leaf temperature varying from an ambient temperature. In a method for growing the plant a carbon dioxide assimilation management of a leaf system of the plant is thus influenced, and a supply of actinic light, the root temperature and the carbon dioxide assimilation management are adapted to each other.

主权项

1. A system for growing a plant, comprising:
a substantially daylight-free, at least partly conditioned environment, said environment comprising a cultivation base for receiving a root system of the plant therein, an artificial light source that exposes the leaves of the plant to artificial actinic light having a lighting spectrum that is adapted to an intended photosynthesis and/or mode of growth of the plant to be cultivated; a root temperature controller that controls the root temperature of the root system; and a leaf heater that imposes on the leaves of the plant a leaf temperature that differs from an ambient temperature within said environment, wherein the root temperature controller comprises a conduit system for receiving therein, during operation, a fluid flow with a controlled temperature, said fluid entering into heat-exchanging contact with said root system of said plant.
