1.Technical content The technology includes: corn germination and drainage machinery sowing mechanization technology and corn germination seed coating technology, respectively, in mechanized and artificial sowing conditions. (1) Mainly aiming at the problems such as the lack of soil moisture and the emergence of seedlings in spring maize planting area in northeast China. Increase in the seeder on the filter device to achieve ditching, sub-drainage, fertilizers deep Shi, complex soil repression and other operations completed once, for seed germination, emergence of water to provide the necessary drought-resistant sowing new technology. (2) Aiming at the technique of germination coating of corn seed in arid areas. Its main technical operation: 1 germination length and coating dose: to promote small bud radicle root length of 1 to 3 mm, germ
