Abstract

This product is a duct that applies a uniform and appropriate amount of target gas (e.g., carbon dioxide gas) to cultivated plants in a horticultural facility such as a greenhouse or a plant factory. As shown in Reference Figure 1, which shows the state of use, this product is installed in a gas application device within a horticultural facility, with a blower attached to the gas supply source, and the product is connected to this blower via a main duct (not shown), etc., and is used by being disposed for each row of cultivated plants, as shown in Reference Figure 2, which also shows the state of use. The target gas supplied from the gas supply source is then supplied by the blower to the product disposed within the horticultural facility, and is applied to the cultivated plants through multiple holes provided in the product.
