Abstract

The air emission device for growing plants includes a plurality of air emission units for respectively emitting an air flow onto the new leaves growing on a tip of a stem of each plant that has one stem. The transpiration effect on the leaves and suctioning of water and nutrition from the roots of the plants can be promoted. Thus, wilting of leaves can be prevented and the tip burn due to insufficient calcium can be avoided. Provision of the air emission units are effectively arranged to evenly or uniformly supply air onto the new leaves of the each plant.

First claim

1 . An air emission device for growing plants comprising:
a plurality of air emission units that respectively emits an air flow onto new leaves growing on a tip of a stem of each plant that has one stem.

2 . The air emission device for growing plants according to claim 1 , wherein, the air of the air flow is adjusted to be air with high humidity and high concentration of carbon dioxide and is supplied to the plurality of air emission units from an air supply source through a pipe.

3 . The air emission device for growing plants according to claim 1 , wherein the each of the plurality of air emission units accommodates therein a fan which generates the air flow to emit the air and a motor which drives the fan.

4 . The air emission device for growing plants according to claim 1 , wherein the each of the plurality of air emission units includes a light emitting device which emits a light onto the plants.

5 . The air emission device for growing plants according to claim 4 , wherein the each of the light emitting devices is provided with a stem growth-inhibiting light source at a central portion thereof for emitting a stem growth-inhibiting light having a blue component light at high ratio, which inhibits a growth of a stem and with a leaf growth-promoting light source around the stem growth-inhibiting light source for emitting a leaf growth-promoting light having a red component light at high ratio, which promotes a growth of leaf.

6 . The air emission device for growing plants according to claim 2 , further comprising:
an air emission unit supporting device which supports and locates the each of the air emission units at a proper position for the same to face to each plant and includes a support bar that extends in a lateral direction above the plants, wherein the support bar is provided with a communication passage therein through which the air supplied from the air supply source flows, a plurality of air emitting ports through which the air flowing through the communication passage is emitted towards the each plant and serving as the air emission unit, and a light emitting device provided around the periphery of the air emitting ports for emitting a light onto the each plant.
