EXPERIMENTAL STUDY ON THE EFFECTS OF DIFFERENT PRESSURE METHODS ON THE GROWTH CHARACTERISTICS OF BUCKWHEAT

In order to fully explore the influence of different pressure methods on growth characteristics buckwheat, a test device with adjustable press force, and easy replace wheel was designed. Using dry matter quality buckwheat roots, stems, leaves at seedling stage, plant height, number main stem nodes, branches, grain per plant, weight yield as evaluation indexes, single factor force carried out, three-factor three-level orthogonal out too outer diameter, type factors. The results showed that index values trend first increasing then decreasing increase force. When 450 N, development performed best. effects different. indexes were greater than diameter. optimal sowing are follows: diameter is 300 mm, conical combined wheel. this study could provide reference for improvement high-yield mechanized technology design rational device.
