微灌系统堵塞是微灌系统运行中常常出现的现象,也是影响微灌技术推广应用的主要障碍。对微灌系统堵塞的主要原因和防治措施进行了阐述和分析,指出水质因素是造成微灌系统堵塞的直接原因,根据水质等因素合理设计和配置过滤设备以及在运行中进行正确的管理和维护是防治微灌系统堵塞的关键措施,而对灌水器经济技术性能的改进则是从微灌技术本身出发寻求解决堵塞的另一有效方法。
The clogging of micro-irrigation system is a common phenomenon in the operation of micro-irrigation system, which is also a major obstacle to the popularization and application of micro-irrigation technology. The main reasons for the clogging of micro-irrigation system and the prevention and treatment measures are described and analyzed. It is pointed out that the water quality factor is the direct cause of the clogging of the micro-irrigation system. The rational design and configuration of the filtration equipment according to the factors such as water quality and proper management and maintenance during operation Is the key measure to prevent and control the clogging of micro-irrigation system. And the improvement on economic and technical performance of the emitter is another effective method to solve the blockage from the micro-irrigation technology itself.
