Rice-broad bean rotation straw-returning farming method

Abstract

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.

Description

technical field [0001] The invention relates to a farming method for planting winter broad beans in rice stubbles and returning the full amount of twice-ripe straws to the field every year. Background technique [0002] Planting winter broad beans after rice harvest is one of the stubble layouts of agricultural production. Straw and beans are multi-purpose renewable biological resources such as fuel, feed and fertilizer. With the change of people's production mode, there is a large amount of surplus straw in the countryside. At present, the utilization rate of straw resources in my country is low, and most of them are discarded or directly burned, which not only wastes resources, but also pollutes the environment. [0003] At present, the cultivation method of rice stubble broad bean square hole planting specifically includes the following steps: [0004] 1. Harvesting rice: After the rice is harvested, carry the straw or burn it on the spot to make room for planting broa...

Problems solved by technology

[0018] The purpose of the present invention is to overcome the defects and deficiencies of the existing rice stubble and broad bean square hole planting methods, which are laborious, delay the season, and the straw cannot be returned to the field. Row spacing, reduced plant spacing, planting without holes, deep ditches to block soil, rice straw to cover broad bean furrows, bean chess to bury bean stubble furrows, providing a farming method for rice and broad bean second-ripe straw returning to the field
