摘要
简述了激光平地技术的特点、实施步骤,提出了提高平地效率的具体措施,并对平地效果进行了评价。指出激光平地的最佳作业时期为4月15日至5月20日,激光平地设备每年作业35d,可直接收入3.15万元,节水26％,投资回收期7a。虽然一次投资较大,但综合效益显著。
State the technological characters and operating steps of leveling the land with laser. Refer to the specific countermeasures of improving efficiency, and appraise the effect. Point out the better time of leveling land with laser is April 15 to May 20; 35 d work can earn 31 500 yuan directly and can save water 26%. Recovering investment time is 7 a. The onetime investment is rather more but comprehensive effect is outstanding.
