| Abstract: | Biological characteristics of corn seeds like structure,germination and emergence were summarized.Relationship of direction of seed in the soil and leaf growth was expounded by actual investigation.Based on agronomic research,techniques of corn mechanical precision directional precision sowing were proposed,and structure of directional and precision seed metering device was introduced.Pass rate of directional and precision sowing was more than 80% on test bed.Application of directional and precision sowing techniques can ensure planting density,but also take full advantage of the sun’s light and heat,to ensure high and stable yield of corn. |
