Abstract

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 is high in return rate.

Description

technical field [0001] The invention relates to the technical field of planting and breeding, in particular to a crop rotation planting method of Procambarus clarkii and medium rice for stabilizing grain and increasing fish. Background technique [0002] Low-lying and low-yield rice fields are prone to water accumulation in winter and spring, so it is not suitable for planting rape and wheat in the idle season of the paddy field. Only one season of rice can be planted, and the planting method is single, that is: "planting and raising". "Only planting but not raising", the fertilizer used for farming can only rely on chemical fertilizers, and after chemical fertilizers are applied, only 35% of them are effective, and the remaining 65% become pollutants and remain in the environment. This single operation method not only causes environmental pollution, but also has low economic benefits. Paddy fields only grow rice, and the benefit is only 200-300 yuan / mu, which does not incl...
