This invention discloses a simplified method for
orchard ground cover, mulching, and mechanized precision
sowing and fertilization, comprising: dividing the
orchard ground into inter-row work zones and tree basin protection zones; using a seed-
fertilizer co-
sowing device to create strip-shaped furrows in the inter-row work zones, forming deep trenches and shallow
sowing zones; applying controlled-release
fertilizer to the deep trenches and sowing complementary mixed grass seeds in the shallow sowing zones; when the height of the
composite surface vegetation community reaches the preset mowing height, performing mowing operations and transferring the mowed herbaceous
biomass to the tree basin protection zone to form a
mulch layer; measuring the
mass of the herbaceous
biomass transferred to the tree basin protection zone, calculating the
nitrogen supplementation amount according to a preset
nutrient compensation coefficient, and applying
liquid nitrogen fertilizer to the inter-row work zones and tree basin protection zones. This invention enables integrated and coordinated management of
orchard ground cover, sowing, fertilization, mulching, and
nitrogen supplementation, improving the orchard's year-round ground cover capacity and mechanized operation efficiency.
