Novel ecological paddy field with symbiotic association of loaches and paddy rice

The utility model relates to a novel ecological paddy field with symbiotic association of loaches and paddy rice. A circular furrow is arranged between the paddy field and borders of the field and crisscross furrows are arranged in the field; the circular furrow and the crisscross furrows aggregately cover 10-12 percent of the total area of the field; nets preventing the field against land enemies and a net preventing the field against water birds are respectively mounted surrounding the field and on the top surface of the field by fixed brace bars; an inflow pipe and a drain pipe are positioned respectively on the borders at the two sides corresponding to the field; and an inlet of the inflow pipe and an outlet of the drain pipe are respectively located on the diagonal of the field. The utility model has the advantages of simple structure, low material demands, complete structure preventing the field against both land enemies and water birds, thereby ensuing stable water quality; the circular furrow and the
