美国农业部灌溉研究实验室研制成功了用激光指挥的滴灌装置,目前正在制订程序,以便用电子计算机提供大田综合情报,做到有针对性地安排灌溉。这套激光滴灌装置由主塔和几个附属塔组成。主塔沿着一条盛水的混凝土灌溉槽活动,并与其他塔连成一线。塔底装有活动轮子,每塔均有激光接受器,接受器又与一小型电动机相连,电动机用于推动塔的前后移动。激光接受器用来控制各塔排列成一个平
The U.S. Department of Agriculture’s Irrigation Research Laboratory has successfully developed a laser-guided drip irrigation device and is currently in the process of developing procedures to provide computer-based field synthesis information so that irrigation can be targeted. This set of laser drip irrigation equipment consists of a main tower and several auxiliary towers. The main tower moves along a water-filled concrete irrigation channel and is in line with other towers. The bottom of the tower equipped with movable wheels, each tower has a laser receiver, the receiver is connected with a small motor, the motor is used to promote the tower back and forth. The laser receiver is used to control the columns to be arranged flat
