System and method for breeding pelophylax nigromaculatus in rice field

Abstract

The invention relates to a system and method for breeding pelophylax nigromaculatus in a rice field. The system comprises a rice planting mechanism, a pelophylax nigromaculatus breeding mechanism andan escape prevention mechanism, wherein the rice planting mechanism comprises a rice planting area and rice; the pelophylax nigromaculatus breeding mechanism comprises a ditch formed in the middle ofthe rice planting area, and the ditch longitudinally runs through the rice planting area; the pelophylax nigromaculatus breeding mechanism also comprises a feeding platform arranged around the rice planting area, and the feeding platform is used for putting food needed by pelophylax nigromaculatus; the rice is densely planted in two rows close to a ditch area, and the planting density is sequentially reduced in the direction towards the end away from the ditch; the escape prevention mechanism comprises escape prevention baffles arranged around the feeding platform. According to the system, theditch is formed in the middle of the rice planting area, and pelophylax nigromaculatus is bred while the rice is planted; moreover, since pelophylax nigromaculatus is adept at catching pets in the rice field, not only do the pests of the rice serve as baits for pelophylax nigromaculatus, but also the excrement of pelophylax nigromaculatus is organic fertilizer for rice.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a system and method for cultivating black-spotted frogs in paddy fields. Background technique [0002] The black-spotted frog (scientific name: Pelophylax nigromaculatus) is an amphibian of the family Ranaidae and the genus Pelophylax nigromaculatus. The male black-spotted frog is slightly smaller, the head length is slightly longer than the head width, the snout is blunt and round and slightly pointed, the snout ribs are not obvious, the forelimbs are short, the hind limbs are short and fat, the tibia joints reach the eyes in front, and the toes are almost completely webbed. The back color is dark green, yellow-green or brown-gray, with irregular black spots, and the belly color is white without spots. Black-spotted frogs like to live in groups and live amphibiously on land and water. They come out after dusk and at night to hunt, hibernate, and are ...

Problems solved by technology

[0004] However, the current symbiotic culture system of frog and rice is not perfect, and it cannot adjust the water level of the paddy field in real time according to the demand of frog and rice, and when the frog and rice are symbiotically cultured, the fertilizer produced by the frog cannot evenly and fully flow to the rice planting area , causing most of the nutrients produced by the frogs to slip away with the water, resulting in a great waste, and it cannot promote the growth of rice in the symbiotic system
