Procambarus clarkii and semilate rice rotation planting method capable of stabilizing grain income and increasing fishery income

The invention discloses a Procambarus clarkii and semilate rice rotation planting method capable of stabilizing the grain income and increasing the fishery income. The method includes the steps: selecting a rice field, and digging circular Procambarus clarkii breeding ditches and field furrows, wherein the total area of the circular Procambarus clarkii breeding ditches and the field furrows is 5-10% of the area of the rice field; increasing the height and the width of ridges, reinforcing the ridges, flatting a filed surface; additionally arranging escape-proof facilities in a drainage opening; transplanting rice seedlings in the rice field in the first ten days of June, wherein the density of the rice seedling is 1.3-1.5 ten thousand/mu; stocking the Procambarus clarkii parents; and performing daily management. The Procambarus clarkii and semilate rice rotation planting method can cultivate the rice and the turtles together, is low in technical difficulty, is small in investment, is low in breeding risk, and
