The present invention discloses an inner-periphery ridge building method for a shrimp and rice joint culturing mode, wherein a ridge is built, in a rice field with an enclosed ditch, along the enclosed ditch; the ridge has a height of 20-40 cm and a bottom width of 30-50 cm; the ridge goes around the rice field and an outer edge of the ridge has a distance of 40-60 cm from an inner edge of the enclosed ditch; and the soil for building the ridge comes from the outer side of the ridge, and 15-25 cm thick surface soil is fetched on the outside surface of the field to build the ridge. When field sunning is needed in a rice growing season, a water outlet is arranged on the inner ridge and the water surface of the enclosed ditch is made to be lower than the field surface by using drainage and irrigation equipment; during rice fertilization, the water outlet on the inner ridge must be blocked to prevent fertilizers from flowing into the ditch; and after middle-season rice or late-season rice have been harvested, the field is irrigated to be filled with deep water, ensuring that the water surface is higher than the inner-periphery ridge, so that the entire field surface can culture small lobsters; in the following year and before transplanting of the next-season rice, the inner-periphery ridge should be reinforced to prevent leakage. The inner-periphery ridge building method of the present invention enables the water surface of the cultural ditch and the water surface of the rice field to be manually isolated and controlled, facilitating farming operation and water and fertilizer management of the rice field.

The invention discloses a method for producing aquatic vegetables and a green manure during crop rotation of water mimosa and paddy rice. With the method, paddy rice and water mimosa are planted according to a certain ratio during a double-cropping rice period. Water mimosa can grow together with paddy rice in a paddy environment. Rhizobium of the water mimosa on the part on the surface of the paddy can fix nitrogen, such that soil nitrogen content can be increased. After the harvesting of early-season rice, the edible parts of water mimosa are harvested, and all the non-edible parts are turned back to the field as green manure; after the harvesting of late-season rice, winter cropping of water mimosa is carried out; about 1 month before early-season rice planting in the next year, the edible parts of the winter-cropping water mimosa are harvested, and all the non-edible parts are turned back to the field as green manure. With the paddy rice and water mimosa crop rotation method, soil fertility can be maintained on a basis of increasing paddy rice yield. Also, the use of chemical fertilizer nitrogen can be reduced, such that non-point source pollution caused by paddy rice production can be retarded.

The invention discloses an improvement method for organic maturation of yellow mud fields. For an early season rice field, the improvement method includes the steps: 1), planting astragalus sinicus and applying inorganic fertilizer; 2), applying nitrogen fertilizer at a stage when astragalus sinicus sends forth a first true leaf, wherein scalar quantity of the nitrogen fertilizer is 6.9-10.35 kilograms per hectare; 3), reapplying the nitrogen fertilizer at a stage when astragalus sinicus grows vigorously, wherein scalar quantity of the nitrogen fertilizer is 17.25-34.5 kilograms per hectare; 4), taking astragalus sinicus as green manure to be returned to the field, and applying chemical fertilizer. For double cropping rice, the improvement method includes 1), directly returning straw of early season rice into field in situ, or applying livestock and poultry manure for soil maturation; 2), additionally applying nitrogen fertilizer, and adjusting C / N ratio of the straw; 3), applying rotten organic fertilizer or mushroom residue before seeding middle-season rice or late-season rice; 4), performing light dewatering and ventilating after transplanting of the middle-season rice or the late-season rice, and re-watering. By the improvement method, soil structure is improved, soil volume weight is lowered, soil cation exchange quantity is increased, community structure of soil microorganisms and soil enzyme activity are affected.
