Bait-feeding device and bait-feeding method in a rice-fish symbiosis system

Abstract

The invention discloses a bait throwing device and a bait throwing method in a rice-fish symbiosis system, which comprises a track erected on the upper part of one of the fish ditch, and a material box slidingly matched with the track, and a bait outlet is fixed at the bottom of the material box. The bottom of the bait outlet is fixed with a reciprocating leveling mesh plate, which slides reciprocatingly along the track fixed below the material box by a bracket, and a mesh eating platform is fixed under the reciprocating leveling mesh plate. A filter is fixed below to prevent the bait from sinking. By adopting the method of the invention, the bait waste rate can be effectively reduced, the residual bait that has not been eaten can be cleaned up in time, and the disease probability of fish can be reduced.

Description

technical field [0001] The invention relates to the technical field of rice-fish symbiosis, in particular to a bait feeding device and a bait feeding method in a rice-fish symbiosis system. Background technique [0002] Raising fish on the surface of rice fields can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn the soil to promote fertilizer decomposition, and create good conditions for rice growth. Generally, rice production can be increased by about 10%. . However, during the growth process of fish, the pests and weeds in the rice fields cannot meet their growth needs, and at this time, bait needs to be added manually. Because of the central Yudang (pit) commonly used in the prior art, the multiple fish ditches connected to Yudang are stocked with fish, and the rest are planted with rice. If a conventional bait feeding device is used, bait may be thrown into the Areas without fish, or areas where fish are con...

However, during the growth process of fish, the pests and weeds in the paddy fields cannot meet their growth needs, and at this time, bait needs to be artificially added

Because of the central Yudang (pit) commonly used in the prior art, the multiple fish ditches connected to Yudang are stocked with fish, and the rest are planted with rice. If a conventional bait feeding device is used, the bait may be thrown into the Areas without fish, or areas where fish are concentrated, such as the central fish farm, can not be fed, and the bait throwing device of the prior art only throws bait, no matter whether the bait is eaten by the fish in time, if the bait is not eaten by the fish Eating it in time will not only result in low bait utilization, but also deteriorated bait will easily damage the water quality.
