摘 要:针对现有中心支轴式喷灌机悬吊装置不能随作物长势进行调整,造成田间灌溉水利用率和灌水均匀度降低的实际问题,创新研制了可伸缩悬吊装置,可使喷头升降幅度达100cm,实现作物“贴合式”喷灌。中心支轴式喷灌机应用可伸缩悬吊装置后,喷洒均匀系数在72.3%~94.1%之间,田间灌溉水利用率在82.8%~89.8%之间。可伸缩悬吊装置能够有效减少灌溉水的飘移损失,提高田间灌溉水利用率和灌水均匀度。The retractable suspension of center pivot sprinkler was developed to solve the practical problem that the field irrigation water effective utilization and irrigation uniformity were lowered because the suspension can’t adjust with crop growth.The retractable suspension could achieve crop“fit”sprinkler irrigation by way of adjusting the sprinkler head height and the lifting range could reach 100 cm.The field irrigation water effective utilization stabled between 72.3%and 94.1%and the irrigation uniformity stabled between 82.8%and 89.8%after using this device.This equipment could effectively reduce the drift loss of irrigation water,and enhance the field irrigation water effective utilization and irrigation uniformity.
