Abstract
The precision seeder seeding accuracy not only with the seed metering device performance , seeding unit speed , soil moisture and other relevant factors , but also has the very big relations with the planter for the opener , the for-mation of different types of seed ditch shape is different , have a certain effect on the sowing depth and spacing .Test re-sults show:a V shaped seed ditch with seed ground scattering , bounce and rolling of small advantages , but also has a flat hard bottom seed furrow depth and good consistency , when the seeds fell into the ditch , wedge and seed size adapta-tion of the ditch without rolling .So the opener design reasonable section shape , is the key to improve the seed sowing machine precision .关键词
