摘要：
A system or method for dispensing seeds and chemical granules, in which chemical granules are dispensed through a granule tube into a seed dispensing tube, where the granule tube is connected to the seed dispensing tube at a location above a lower opening of the seed dispensing tube, and where the lower opening of the seed dispensing tube is covered with a brush. A seed is dispensed through the seed dispensing tube. The brush holds chemical granules within the seed dispensing tube such that chemical granules accumulate within the seed dispensing tube, and the brush allows a seed and accumulated chemical granules to pass through the lower opening when the seed is dispensed via the seed dispensing tube.
