Abstract: A method for building a farmland ecosystem with multiple mutual-benefit species in multiple habitats is provided. The method includes: marking out an ecological field plot for planting crops in a farmland, arranging one to three earthworm breeding strip stack(s) at equal intervals, and marking out different planting areas; digging an ecological field ditch surrounding a periphery of the ecological field plot, and planting aquatic plants and breeding aquatic animals in the ecological field ditch; surrounding a periphery of the ecological field ditch with an ecological wide ridge, planting forage plants on a ridge surface of the ecological wide ridge, and planting arbors on an outer side of the ecological wide ridge; and arranging an ecological pond on a drainage side of a hole, wherein aquatic plants are planted in the ecological pond, and crustaceans are bred in the ecological pond.

Abstract: The present disclosure relates to a method for building a farmland ecosystem with multiple mutual-benefit species in multiple habitats, and belongs to the technical field of agroecological environment. The present disclosure improves the resource utilization efficiency of the farmland ecosystem to the maximum extent, greatly reduces application of chemical fertilizer and pesticides, and reduces environmental damage and pollution. By means of different ecological niches of living things, a beneficial ecological service function is brought into play such that species in the farmland ecosystem can live in a suitable farmland microenvironment, competition for the same living space in the same place is avoided, and harmonious coexistence among the living things is realized; and food with high quality and a higher grain output value are provided.
