METHOD FOR ADDITIONAL FERTILIZATION OF CUCUMBER CULTURE WITH CARBON DIOXIDE Russian patent published in 2020 - IPC A01C21/00 A01G22/05 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method includes supply of carbon dioxide via pipelines with drip irrigation water outlets. For cucumber culture, strips with width of 1.0–1.2 m are prepared. In the middle of each strip a furrow is cut with depth and width of 15–20 cm, divided by jumpers into pieces with length of 1.5–2 m. Pipeline with drip irrigation water outlets is laid on said webs to cover strip with 0.5–0.6 m-thick membrane film with its edges poured with soil. Along the furrow on both sides in the membrane film holes are made for the cucumber culture. During fertilizing through drip irrigation pipeline outlets, carbon dioxide is fed, which is filled with volume of furrows under the screen.

EFFECT: method provides uniform increase of concentration of carbon dioxide in surface air layer of field without pollution with atmospheric carbon dioxide.
