CO2 fertilizer injection unit that facility vegetables were used

The utility model discloses a CO2 fertilizer injection unit that facility vegetables were used, fertilizer injection unit's gas source device is connected with CO2 pressure reducer, gas valve, clamp, high -pressure air hose, quick -operation joint, high -pressure air hose tee bend, gas transmission trunk line in proper order, and the gas transmission trunk line is connected respectively with one row of gas transmission hollow billet, couples together through the tee bend of gas transmission trunk line, delivery valve and lock nut between gas transmission trunk line and every gas transmission hollow billet. Fertilizer injection unit uses CO2 pressure reducer and gas source device connection control output CO2 atmospheric pressure, up to gas delivery to every trunk vegetable crop stem foot portion. The realization is evenly discharged to the CO2 of vegetable crop plant stem foot portion by CO2 gas source device. Use this fertilizer injection unit to have the uniform of application of the facility of realization environment CO2 and flow with the peripheral air of increasing vegetable crop, weaken the gas pocket external resistance, promote photosynthesis's effect.
