Rice and chicken lobster continuous mixing planting and breeding method capable of stabilizing grain income and increasing fishery income

Abstract

The invention discloses a rice and chicken lobster continuous mixing planting and breeding method capable of stabilizing the grain income and increasing the fishery income. The method includes: digging circular furrows in a rice field, increasing the height and the width of ridges, reinforcing the ridges, and additionally arranging escape-proof facilities; transplanting Ceratophyllum demersum and Alternanthera philoxeroides in the circular furrows after water in the rice field is disinfected; transplanting Hydrilla verticillata, Potamogeton maackianus and Potamogeton wrightii in the rice field outside the circular furrows; performing a rice and chicken lobster continuous cultivation mode, breeding chicken lobsters from the last ten days of September or the first ten days of October to the first ten days of June of the secnd year after the rice is harvested; raising rice seedlings in a special field from May to the first ten days of June, and planting the rice from the middle ten days of June to the last ten days of September; using a ground cage to catch the chicken lobsters from May to the first ten days of June, and leaving a part of the chicken lobsters to be cultivated with the rice; putting parent chicken lobsters into the circular furrows of the rice field from the middle ten days of August to the first ten days of September; applying a fermentative organic fertilizer and putting Bellamya quadrata from the last ten days of February and the last ten days of May; putting Elodea nuttallii from March to June; feeding the chicken lobsters with a compound fodder at 18 p.m. to 19 p.m. every day; controlling the water level all through the year; controlling diseases of the chicken lobsters; catching the chicken lobsters; and planting the rice.

Description

technical field [0001] The invention relates to the technical field of planting and breeding, in particular to a method for co-cropping rice and shrimp continuous cropping 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 does not include the...

Problems solved by technology

However, there are still some problems in the existing rice and crayfish comprehensive breeding model, such as high investment, low return rate, high technical difficulty, and high breeding risk.
