    • 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.
    • 用于分配种子和化学颗粒的系统或方法,其中通过颗粒管将化学颗粒分配到种子分配管中,其中颗粒管在种子分配管的下部开口上方的位置连接到种子分配管 ,并且种子分配管的下部开口被刷子覆盖。 通过种子分配管分配种子。 刷子将化学颗粒保持在种子分配管内,使得化学颗粒积聚在种子分配管内,并且当通过种子分配管分配种子时,刷允许种子和累积的化学颗粒通过下部开口。
