According to the needs of the actual production, on the premise of meeting the reqirement of precise seed sowing, the cost should be cut down and the speed increased. The precision planting provides accurate amount of seeds to soil at equal interval within rows and seeding depth. This planter is mainly comprised of the aperture-mould metering-device, fertilizer-carried pipe, seeds-carried pipe, double disics opener, covering and suppressing device; it is a complicated process comprising of ditching, fertilizing, planting, covering and suppressing; the requirements of its field performance are quite strict; it is designed to be 2 rows planter to improve its work speed and double discs opener is adopted, which ditches oderly, runs stably, and can be suitable for high speed. It has the characreristics of compact structure, simple transmission and riable performance, can sow different kind of seeds, such as maize, soybeans. Combined with fertilizing device, the planter can be designed to sow seeds and fertilizer at the same time. The planter has a widespread prospect of application. </p><p>This article introduced the system of the fast and precise seed sowing machine. Its principle is the following: as the plater runs, the fertilizing disc turns to ditch, and the soil-wheel runs and drives fertilizer-drain shaft rotates via chains transmission; the fertilizer discharged by the box is fertilized into the soil; double disics opener turns and ditches with certain depth through depth-limited wheel; ditches-pressing blades enlarge the ditches; the seeds discharged by metering-device arrive at the ditches through seeds-carried pipe; and the suppressing V-wheel behind suppress the soil into the ditches with seeds and cover it with the soil at the same time. Thus, the requirement of precision planting has been completed.</p><p>Key words：Seed; Aperture-mould Metering-device; Double Disics Opener; Suppressing V-wheel; Depth-limited Wheel</p><p>目錄</p><p>摘
