In order to solve the problem of low mechanization level hairy vetch harvesting, a feeding device for an anti-winding harvester was designed. Firstly, physical properties stalk were studied. According mechanical stalk, key components designed and analyzed, structure working principle described. Secondly, discrete element method used simulate analyze movement performance device. On this basis, t...

Cover crops can determine positive benefits on soil fertility and rice productivity, although scant attention has been devoted to evaluating the effects of hairy vetch (Vicia villosa Roth) incorporation straw with different N fertilization levels P availability crop yields in temperate cropping systems characterized by poorly developed soils. In this study, cover grown before a mono-cropping sy...
