摘要：
The invention concerns an agricultural liquid application system for a liquid distributor, for example a multi-row planter (3, 23) drawn by a tractor (4, 24), that moves over a land to which agricultural liquid is to be applied at multiple application locations. The agricultural liquid may for example be a liquid fertilizer, pesticide and/or herbicide. The system of the invention has delivery lines (14, 214) for delivering liquid to the multiple application locations as the liquid distributor moves over the land as well as pumping means (7, 27) for pumping liquid through the delivery lines at a rate dependent on the speed at which the liquid distributor moves over the land. Also included are a programmable system control means (46, 246) which can be programmed with a target liquid flow which is to be delivered through the respective delivery lines to the application locations and flow monitoring means (16, 16', 216) associated with the respective delivery lines to monitor the actual flow of liquid delivered through each delivery line. The flow monitoring means outputs to the control means signals which are related to the actual, monitored flow. A flow control means (80, 280) is also provided in each delivery line for controlling the actual flow of liquid through that delivery line. The system control means is arranged to receive the signals output by the flow rate monitoring means and to control the operation of the flow control means in order to align the actual liquid flow delivered in each delivery line with the target liquid flow in the delivery line.L'invention concerne un système d'application d'un liquide agricole pour distributeur de liquide, par exemple pour un semoir en lignes (3, 23), tiré par un tracteur (4, 24), qui se déplace sur une parcelle de terre sur laquelle un liquide agricole doit être appliqué en de multiples points d'application.
