Abstract:Sprinkler irrigation can effectively reduce the rate of frostbite on cash crop buds and young fruits. In this study, we propose applying the rotational irrigation method in frost protection to achieve water conservation, simplify the sprinkler system and expand the frost protection area. The freezing test of various sprinklers in a frosty environment (approximately −4.0°C) was conducted to determine the maximum duration of sprinkling cessation for the microsprinkler, butterfly‐shaped sprinkler, impact sprinkle… Show more
