Abstract: There is a short non-frost period in Xinjiang. For achieving twice mature in one year and changing traditional mode of farming, the 2BCM-6 type stubble no-tillage seeder was manufactured. It can achieve cover-sowing of the oil-sunflower's seed in no-tillage wheat stubble. The article introduced the seeder's entire structure, working principle and design of the main parts. The test results showed that with average of 1.69 grain per hole, the qualification rate exceeds 98.7%, the hole length in 1～3 cm reaches over 99.3%, the space of average grain is 19cm, the variation rate is lower than 19.6%, the pass rate of average grain space is over 94.9%, resowing factor is lower than 1%, miss-seeding rate is lower than 2.9%. The machine's index is satisfactory for requirement, and quite stable operating reliability is obtained. Compared with traditional tillage-sowing, it can sow in time, lessen water evaporation, lessen drainage, increase the ability which stores up water in soil. Its capability obtained is steady and reliable. Its working quality can meet agricultural requirements completely.
