This invention discloses a method for intercropping multiple forage grasses in citrus orchards. Addressing the drawbacks of traditional clean cultivation management and single-grass intercropping in citrus orchards, it employs a mixed sowing of four varieties: ryegrass, white clover, gnaphalium affine, and milkvetch. It includes standardized steps for orchard pretreatment, seed pretreatment, precision sowing, seedling management, growth period management, forage harvesting and returning to the field, and water and fertilizer regulation. Strict control of parameters at each stage is maintained, and a specific ratio of compound bio-fertilizer is selected to optimize the citrus water and fertilizer management scheme. This invention achieves year-round closed coverage of the citrus orchard through the complementary characteristics of the four forage grasses, improving the control rate of noxious weeds, reducing soil erosion, increasing soil organic matter content, and increasing citrus yield per acre. It combines the advantages of improving soil fertility, suppressing weeds and conserving moisture, improving quality and efficiency, and promoting a green and ecological environment, thus constructing a highly efficient and sustainable citrus ecological planting system.
