How to mechanize the fine seeding of corn
(1) the northeastern region with 65 cm row ridge for planting, and gradually to 60 cm parallel spacing for the development of planting methods.
Huang Huaihai area with 60 cm and other spacing planting methods, before the wheat planting should be considered corresponding to the needs of corn planting line spacing; the western region with wide and narrow line covered area, should also try to uniform width and width of the line.
Southwest and southern planting area, combined with the local reality, reasonable to determine the relatively stable, suitable for mechanical operation of the planting line spacing and planting mode, with the selection of small and medium-sized fine planting equipment for planting.
