The invention discloses a rice-broad bean rotation
straw-returning farming method. The method comprises the following steps of: (A) harvesting rice; (B) plowing broad bean furrowed fields, wherein the width of a furrowed field surface is 100cm and the width of a furrow is 40cm; (C) applying base fertilizers in furrows, namely applying fertilizers to the inner sides of the furrows; (D) planting
broad beans, namely planting two rows of
broad beans in each furrowed field; (E) performing
straw returning, namely uniformly covering all straws on furrowed field surfaces between every two rows of the
broad beans; (F) banking up soil of deep furrows, namely performing deep
tillage on the furrows and uniformly moving upturned soil onto the straws of the furrowed field surfaces; (G) performing field management; and (H) harvesting the broad beans, and preparing to
plant the rice, namely uniformly pressing all broad bean stalks in the furrows, burying the broad bean stalks by ploughing broad bean stubbles and preparing to
plant the rice. By the farming method, the rice and the broad beans can be ploughed in
spite of sunny days, rainy days, dry fields or poor fields. The straws are planted in autumn to cover the spare spaces of the broad bean furrowed field surfaces; the broad bean stalks are planted in summer to cover the furrows; and the
straw returning is listed in the farming procedures of the rice and the broad beans. By the method, the environment is protected, the soil is fertilized and improved, the rice and the broad beans have high and stable yields, and economic, social and ecological benefits can be improved.
