Recently, Zibo Agricultural Machinery Research Institute designed and developed a new type of corn precision sowing machinery - the 2BYJ type corn precision seeder. The machine passed the promotion appraisal by Shandong Province Agricultural Machinery Test & Appraisal Station, and entered the Shandong Province agricultural machinery product subsidy catalog. This new type of corn precision seeder integrates deep application of compound fertilizer, seeding, soil covering and compaction. It has features such as step-adjustable plant spacing, stepless adjustable row spacing, single-grain precision seeding, etc., compared with traditional seeders it has advantages such as saving seeds, labor, cost reduction and efficiency improvement. The two-row corn precision seeder can realize regulation of row spacing in a large range and cutter adjustment, thereby adapting to plots of different widths; the 18-gear new type corn precision seeder can realize plant spacing adjustment from 2cm to 43cm, thereby meeting requirements of different regions. The new type corn precision seeder will play a huge role in promoting corn live stubble direct seeding operations in the city. (Yuan Dong)
