喷灌系统的技术经济指标,是衡量喷灌技术水平高低的重要标志,是制定喷灌发展计划与政策,进行喷灌系统规划设计和指导运行管理不可缺少的依据。1977～1978年我们在通辽万亩喷灌试点的较大面积上,对试点采用的通辽二型小型移动式喷灌机,进行了喷灌技术经济指标的测定。两年来的实践,使我们体会到,决不能单凭一些粗略的或不确切的调查数字进行统计分析,而要进行一系列必要的测定、调查和综合分析,这项工作实质上是对喷灌设备的工作性能、喷
Technical and economic index of sprinkler irrigation system is an important symbol to measure the level of sprinkler irrigation technology. It is an indispensable basis for formulating sprinkler irrigation development plan and policy, planning and designing irrigation sprinkler system and guiding operation and management. From 1977 to 1978, we piloted Tongliao No.2 mobile irrigation machine on the large area of Tonghua mu irrigation sprinkler to carry out the economic measurement of sprinkler irrigation technology. The practice of the past two years has enabled us to realize that we must not conduct any statistical analysis based on a few rough or imprecise surveys but conduct a series of necessary measurements, surveys and comprehensive analyzes. This is essentially a measure of the effectiveness of sprinkler irrigation equipment The working performance, spray
