AGRICULTURAL AIR INJECTION APPARATUS

摘要

The present invention relates to an apparatus that injects air directly into soil so that a crop yield can be increased and harvest quality can be improved based on aerobic microbe breeding in the soil for cultivation. An agricultural air supply apparatus according to the present invention includes: a compressor generating compressed air; an air tank provided with a pressure gauge and a safety valve for overpressure prevention and storing the high-pressure compressed air under a set pressure condition; a decompression valve reducing the pressure of the air discharged from the air tank; a sprayer spraying water in the form of fine particles so that vapor is included in the supplied air; a distributor uniformly distributing the decompressed compressed air into a plurality of flow paths and opening and closing the flow paths performed by a control valve; an air supply pipe buried in the soil where a crop to be cultivated is planted and having a perforated portion for supply of the air passing through the distributor; and a control unit connected to the compressor, the pressure gauge of the tank, and the control valve of the distributor and controlling the supply of the compressed air. When the agricultural air supply apparatus is used, breeding and activities of aerobic microbes can be enhanced based on continuous air supply at a constant pressure, and thus the crop quality can be improved, blight resistance can be enhanced, and the yield can be increased. In addition, the underground conduit for air supply facilitates drainage in a rainy season, and thus flooding can be prevented and excess moisture injury can be minimized.
