Rice field-based polyculture juvenile crab breeding method

Abstract

The invention discloses a rice field-based polyculture juvenile crab breeding method. The rice field-based polyculture juvenile crab breeding method comprises the following steps that S1, a suitable rice field is selected for erecting an escape-proof wall; and S2, a culture pond is spliced through cooperation of an inner ring steel frame, inner columns and inner arc plates, and the water level in the inner arc plate is limited to prevent water overflow through cooperation of a water outlet, a gate and a floating plate. Meanwhile, a communicating pipe is arranged, and water replenishment is carried out according to the water level in the inner arc plates; the rice field-based polyculture juvenile crab breeding method is scientific and reasonable in structure and safe and convenient to use, the inner ring steel frame is matched with the inner columns, the inner arc plates are assembled into the culture pond, when rainfall in the rainy season is large, the water level in the inner arc plates rises to push floating plates, the gate is driven to ascend through cooperation of a lifting plate and an adjusting rod, sealing of a water outlet is relieved, water in the inner arc plates is conveniently drained, the water level in the inner arc plates is prevented from being too high, juvenile crabs are prevented from climbing out of the inner arc plates, death of the juvenile crabs is reduced, and loss is reduced.

Description

technical field [0001] The invention relates to the technical field of crab breeding, in particular to a paddy-field-based hybrid crab breeding method. Background technique [0002] In recent years, problems such as high dependence on chemical fertilizers and pesticides, increasing pests and weeds, declining soil production capacity, and environmental pollution have become important factors that limit the development of a single rice farming model, affecting rice yield and rice quality. The river crab farming mode has the problems of polluting water quality and destroying the ecology, and it is imminent to develop new rice planting and river crab farming technologies; [0003] However, existing crabs are easily affected by precipitation in the process of breeding and breeding, so that the water in the breeding pond overflows, and the crabs are easy to run out from the inside of the breeding pond, causing the death of the crabs, which affects the breeding effect and increases...
