摘要
介绍了几种目前常用的地下滴灌防根系入侵的措施,包括机械保护及通过灌溉系统给滴头周围土壤注入少量除草剂氟乐灵等。。在简要叙述了氟乐灵的作用机理和、物理特性的基础上、重点介绍了含有氟乐灵成分的几种专用滴头ROOTGUARD、Battelle Process和专用过滤器Techfilter及在灌溉系统中直接加入氟乐灵等方式的工作原理和应用方法。
Several common measures of root intrusion protection in subsurface drip irrigation are introduced in this paper, including mechanical protection and injecting a little Trifluralin herbicide into the soil around emitters through irrigation system. On the basis of expounding the functional theory and chemical & physical properties of Trifluralin, the authors introduced the functional theory and application method of three ways using Trifluralin, including incorporating Trifluuralin into several special emitter (ROOTGUARD brand, Battelle Process brand) and filter (Techfilter brand), and providing irrigation system with Trifluralin directly.
