Procambarus clarkii, soft-shelled turtle and rice integral planting and breeding method capable of stabilizing grain income and increasing fishery income

Abstract

The invention discloses a Procambarus clarkii, soft-shelled turtle and rice integral planting and breeding method capable of stabilizing the grain income and increasing the fishery income. The method includes the following steps: A, selecting a paddy field with sandy soil as a rice field, repairing the rice field, digging furrows and channels, and additionally arranging escape-proof facilities around the rice field; turning over the rice field in winter, disinfecting the rice field through dry-freezing and sunshine in water, using tea cakes or quicklime to disinfect the rice field and kill pests during the first ten days of February; applying a base fertilizer during the middle ten days of February; stacking fermented chicken and duck manure at different sites to fertilize water in the middle ten days of March; stocking Procambarus clarkia parents in the first ten days of March; selecting rice seeds, performing germination accelerating in the first ten days of May, and planting rice seedlings after the age of the rice seedlings is 25-35 days old; stocking young soft-shelled turtles: drain water on a surface of the rice field to the furrows in the rice field when the rice seedlings turn green in the last ten days of June, drying the rice field in sunshine according to the environment temperature, adding water, increasing the depth of water till the height of rice plants is 10-15 cm after the rice has tillers, disinfecting the young soft-shelled turtles, and putting the young soft-shelled turtles into the rice field.

Description

technical field [0001] The invention relates to the technical field of mixed planting and breeding, in particular to a method for comprehensive planting and breeding of Procambarus clarkii, soft-shelled turtle and rice with stable grain and increased fishery. 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 2...
