The invention relates to the field of rumex eating leaf grass, in particular to a planting technology of rumex eating leaf grass. According to the technical scheme, the rumex eating leaf grass is characterized in that rumex is treated as a material line, hoof leaves are treated as a paternal line, and the rumex eating leaf grass is formed through hybridization by adopting somatic pollen. The hybridization method of seeds of the rumex eating leaf grass comprises selecting flower buds, carrying out castration on the female parent, collecting pollen of male parent, carrying out pollination, performing maintenance management and seeds harvesting. The planting method comprises the steps that land and fertilizer treatment is conducted, seed treatment is conducted, a field is selected to plant seeds or a seedling transplantation method is selected to transplant the seeds. The rumex eating leaf grass is wide in planting range, high in nutrient value, high in emergency rate and high in yield.
