渗灌是目前各种灌水方法中用水量较省、水的利用率较高的一种灌水技术,加上它操作简单,工程造价低,深受群众的欢迎,但它存在着系统容易堵塞、不便检查和维修、可能限制作物根系生长等缺点,尤其灌水器堵塞问题时常是整个渗灌工程的运行陷入瘫痪状态,严重影响渗灌系统的正常工作及其使用寿命。这一问题现在国内外还没有比较成熟的方法可以解决。笔者根据几年来的学习和实践经验,谈谈这方面的体会。1 灌水器堵塞的原因1.1 悬浮固体堵寒 Infiltration irrigation is a kind of irrigation technology with more water consumption and higher utilization rate of water in various irrigation methods at present. With its simple operation and low construction cost, it is welcomed by the masses. However, it is easy to block the system, Inconvenience inspection and maintenance may limit crop root growth and other shortcomings. In particular, the problem of plugging of the emitter is often a paralyzed operation of the entire infiltration project, seriously affecting the normal work of the infiltration irrigation system and its service life. At present, there are no more mature methods to solve this problem at home and abroad. The author based on years of learning and practical experience, to talk about this experience. 1 emitter plugging reasons 1.1 suspended solids blocking the cold
