СПОСОБ И УСТРОЙСТВО ДЛЯ СОЗДАНИЯ ПОЛИВНОЙ БОРОЗДЫ С ПЛЕНОЧНЫМ ПЕРФОРИРОВАННЫМ ПОКРЫТИЕМ

摘要

FIELD: irrigation, particularly artificial water canals. ^ SUBSTANCE: method involves punching perforation orifices in film web; cutting furrows; breaking down and spreading soil lumps; laying perforated film webs along furrow perimeter and securing film web edges to berm. Number of perforation orifices made in film web increases from front furrow end to rear end thereof. Method is realized with the use of device including frame carrying working tool used for furrow cutting. Spreader, perforated film web accumulation means and pressing rollers are serially installed behind the working tool. The spreader comprises two rows of paired rollers freely rotating about their axes fixedly secured to shaft by means of bearings and loaded with spring. Roller is installed behind perforated film web accumulation means. The roller may perform limited vertical movement and is pressed with spring to furrow bottom and sides. Pressing rollers and scrapers are arranged behind the roller. ^ EFFECT: prevention of irrigation water losses during furrow filling with water; elimination of plant rootage damping-off. ^ 4 cl, 3 dwg
