An high-speed vacuum precision planter matched with soybean narrow-row-flat-dense seeding technique was developed,and then the experiments were conducted to test performance .The structure,property and technical indexes were introduced.It is test performance according to soybean inter-plant spacing, seeding depth and fertilizing location . The results showed : the acceptability rate is 76.7%, multiples rate is 9.5%, miss rate is 13.75%, spacing variance coefficient is 23.6 and seeding depth acceptability is 85.19% when planting distance is 8cm; the acceptability rate is 77.4%, multiples rate is 8.29%, miss rate is 14.27%, spacing variance coefficient is 21.6and seeding depth accepta-bility is 85.13% when planting distance is 6cm.It is meeting the requirement on one class product according to the standard of “Quality Classification of Precision Seeder for inter cultivation Crop”.Meanwhile, fertilizing location also sat-isfies agriculture requirement.
