SYSTEM AND METHOD FOR CONTROLLING DRIP IRRIGATION |
摘要 |
Systems and methods for injecting materials into soil within a predetermined geographical area are described. One or more tanks store chemicals and a mixing chamber in an injector mixes measured quantities of the chemicals. The mixture is introduced to a stream of water and thence to the soil. A controller monitors the flow of chemicals and the stream of water and causes the injector to release discrete predetermined amounts of the chemical mixture into the soil at a sequence of injection points. The controller can provide a pulsed signal to control the volume and rate of delivery of water. The controller may operate according to a treatment plan. |
