Air emission device for growing plants

摘要

Provided is an air emission device for growing plants that emits an air flow equally onto a plurality of plants being cultivated in a plant cultivating facility. The device comprises a plurality of air emission units that emit an air flow onto new leaves growing on the tips of the stem of each plant for which one stem grows. An air flow is emitted onto each new leaf growing on the tip of a stem for each plant for which one stem grows by way of the plurality of air emission units. In this way, the transpiration effect from the leaves is promoted by emitting an air flow onto the new leaves growing on the tip of the stem of each plant, and the taking up of water and fertilizer from the roots of the plants is promoted. Thus, the wilting of leaves can be prevented and tipburn due to insufficient calcium can be avoided. Because the air emission unit is disposed near the new leaves of the plants, the volume of air being emitted by the air emission unit can be small, and damage to leaves caused by adjacent leaves contacting each other due to air being blown strongly can be avoided.
