摘要： An applicator for the delivery of dry and liquid materials to turf areas. The applicator (10, 180) comprises frame means (11) supported by ground engaging wheels (14, 15); hopper means (12) carried by the frame for holding the dry materials; sealed reservoir means (39, 181) carried by the frame for holding the liquid materials; impeller means (23) beneath the hopper and rotatably driven to broadcast the dry materials in an arc laterally outside of and in front of the wheels; means (125) for selectively controlling the application of the dry materials; extendible boom means (75) carried by the frame means; pump means (56) for pressurizing the liquid materials to produce a low volume, low pressure spray; first nozzle means (64) located beneath the impeller, in communication with the pump means; second nozzle means (65) carried by the boom means in communication with the pump means; means (130) for selectively activating the flow of liquid material from the pump means; sensing means (135) for independently controlling the flow of the liquid materials through the second nozzle means; and electrically operable valve means (151) for independently controlling the flow of the liquid materials through the second nozzle means. A method for uniform and simultaneous delivery of dry and liquid materials to turf areas can be practiced for continuous and intermittent application of liquid spray during application of dry materials.
