Results of double-strand opener testing in the soil channel in realistic conditions are brought. Mathematical models of uniformity of grain seed distribution on the length and width of sowed strand are received.
Operation of plane hexagonal working organ used on a disk hoeing plough for the cultivation of wind erosional soil was examined. Important regularities were revealed and described, and criterion of quality assessment of weeds undercutting depending on angle, cultivation depth and distance between disks on shaft was presented.
Results of quality assessment of cereals seeds distribution with a two-band ploughshare are given as well as the relationships of seed distribution uniformity and the convergence curves of theoretical and experimental researches.
Uniformity of seed distribution on feeding area and on depth of sowing and crop yield are indexes obtained during field tests of experimental two-band ploughshare (in comparison with series-produced ones) while sowing of “Omskaya-36″ wheat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
