METHOD FOR DRIP IRRIGATION OF FRUIT-AND-BERRY, SHRUBBY CROPS AND FLORAL PLANTS Russian patent published in 2019 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in drip irrigation. When implementing the drip irrigation method of fruit-and-berry, shrubby crops and floral plants, the main polyethylene pipeline is broken into sections with length of not more than 60 m. Pressure distributing polyethylene pipelines are connected to the main pipeline. Places for connection of pressure polyethylene pipes are equipped with metal risers with ball valve. Crane has calibration of water flow rate and is controlled from ground surface. Crane is equipped with a filter and is coupled hydraulically with an additional low-pressure irrigation pipeline of a small diameter in the form of a flexible hose. Hose is equipped with droppers. Hose is placed in cavity of main polyethylene perforated pipeline of large diameter. Outlet openings of pipeline are arranged in its lower part coaxially to droppers. Main polyethylene pipeline with additional irrigation pipeline and with droppers are located above the plantations at the height of not more than 30 cm from the ground surface. Droppers are fixed to walls of irrigation pipeline of small diameter with outlet openings towards outlets of main pipeline of large diameter. Outlets of main pipeline are made somewhat larger than those of droppers. End of irrigation pipeline is equipped with discharge ball valve.

EFFECT: simplicity and reliability of drip irrigation system design is achieved; expanding the irrigation system functionality; providing uniform and optimum mode of drip irrigation taking into account specific conditions of irrigated area.
