Se eding machine is an important ponent part of agricultural machinery, machine will directly affect the quality of agricultural labor productivity and crop yields and agricultural products, so the cost of developing high quality sowing machine is the urge nt requirement of modern agriculture. In recent years, the development of medicine is banlangen economic crops, no matter from domestic and abroad are no special sowing equipment. Due to the particularity of seed, drugradix isatidis existing sowing machinery and equipment cannot be used for planting crops banlangen. Therefore developed new equipment to improve the sow banlangen crop production efficiency and quality. Not only can make the farmers ines, but also can increase agricultural development promoter action. Ke y words: Isatis tinctoria L 。 planter; seed metering device; furrow opener
