A kind of crab-rice symbiotic breeding pond and its comprehensive temperature regulation method

Abstract

The invention discloses a crab-rice symbiotic planting-breeding pool and a comprehensive temperature-adjusting method thereof. By using the crab-rice symbiotic planting-breeding pool, symbiosis and coculture of river crabs and high-straw rice can be realized; the temperature of water in the crab-rice symbiotic planting-breeding pool in hot summer can be controlled below 28 DEG C, so normal feeding and molting of the river crabs in summer can be guaranteed; ventilation, air permeation and enough illumination can be obtained among the high-straw rice; pests parasitized on rice straws can be feeds for aquatic animals like the river crabs and wild fishes; the use of a pesticide is not needed; manures excreted by the aquatic animals like the river crabs and the wild fishes are used as an organic fertilizer of the high-straw rice, so benign ecological balance is realized in the crab-rice symbiotic planting-breeding pool; farmers can simultaneously obtain high-quality organic rice with high yield and large-sized river crabs with high yield; the comprehensive productivity of a crab pool is improved; the product quality is enhanced; and the economic benefits are increased.

Description

【Technical field】 [0001] The invention relates to a symbiotic breeding technology of river crab and rice, in particular to the technical category of reducing the water temperature of crab ponds in high temperature seasons during the breeding process of symbiotic species of crab and rice. 【Background technique】 [0002] River crabs are temperature-changing animals, and the body lacks body temperature regulation function. Changes in water temperature have a direct impact on the growth of river crabs, which determine the output and specifications of adult crabs, and are one of the key factors affecting the economic benefits of river crab farmers. June-September is the peak season for river crab growth in southern Jiangsu. During the crab breeding process, pond water is an essential environment for river crabs to live, and water temperature is a key factor affecting the growth of river crabs. We all know that the optimum growth temperature for river crabs is 20-28°C. When the w...

Problems solved by technology

Due to the high planting density of ordinary rice, the water body in the paddy field has insufficient light, which is not conducive to the growth of river crabs, and also limits the activity space of river crabs. The intertwined rice stems will also cause damage to the residual limbs of river crabs during crawling, affecting the normal growth of river crabs , it is easy to cause the size of river crabs to be too small. Therefore, the economic benefits of the paddy field crab farming model cannot meet people's expectations

Practice has proved that the existing crab farming model in rice fields does not have the prospect of popularization and application, so the crab farming model in rice fields has been gradually eliminated by people
