FIELD: agriculture.
SUBSTANCE: liquid introduction device for introduction of liquid into soil during the sowing operation in the first version contains a component interacting with the ground, installed on seeder sowing section, which cuts sowing furrow and places seeds into it. Component interacting with soil is located at least partially inside specified sowing furrow at movement of sowing section of seeder on field. First liquid spray pipeline is mounted on said interacting component and is configured to inject liquid into first sidewall of said sowing furrow. Second liquid injection pipeline is mounted on said interacting component and is configured to inject liquid into second sidewall of said sowing furrow. Third liquid injection pipeline is installed on the said component interacting with the ground and is made with possibility of liquid injection into the center of the specified seed furrow. Device is also equipped with a first wing configured to cut the first lateral groove in said first side wall, note here that said first fluid injection pipeline is configured to inject liquid into said first lateral groove. Second version of device differs from first one in that it has fluid manifold, installed on said component interacting with ground. Said fluid manifold has first fluid inlet in fluid communication with first and second outlets. First outlet is located in fluid communication with said first liquid injection pipeline, and said second outlet is located in fluid communication with said second liquid injection pipeline. Second inlet in the fluid communication with the third outlet is made with the possibility of liquid injection into the center of the sowing furrow. First inlet and second inlet are located in fluid communication with fluid source.
EFFECT: invention will make it possible to increase efficiency of fertilizer application during sowing.
