Finless eel rice field integral planting and breeding method capable of stabilizing grain income and increasing fishery income

Abstract

The invention discloses a finless eel rice field integral planting and breeding method capable of stabilizing the grain income and increasing the fishery income. The method includes the steps: selecting a rice field, where a land having the pH of 4-7 is used as the rice filed; constructing the rice field, increasing the height and the width of ridges of the rice field, reinforcing the ridges, and additionally arranging escape-proof facilities in a drainage opening; flatting the rice field, and digging drainage ditches; turning over the rice field, drying the rice field in sunlight, smashing soil, and then applying a base fertilizer; applying fermentative chicken manure to the drainage ditches and injecting water from the last ten days of March to the first ten days of April; planting the rice; selecting finless eel fries; stocking the finless eel, disinfecting the selected finless eel fries, and then putting the selected finless eel fries into the rice field; feeding the finless eel with fodder, feeding the finless eel with the fodder once every day during 1-2 weeks after finless eel stocking, wherein the feeding amount of the fodder is 4-8 wt% of the body weight of the finless eel; and then feeding the finless eel with the fodder for 3 times every day, wherein the feeding amount of the fodder is 2-5 wt% of the body weight of the finless eel; managing the water quality, changing water once every 2-3 days in midsummer, and changing water once every 7-10 days in the rest time, wherein the water changing amount is 1 / 3 of water in the rice field; and controlling diseases.

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 eels in paddy fields for stabilizing grain and increasing fishing. 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 do...
