Problems solved by technology

However, the systematization, modeling, and quantification of rice-fishing cooperative farming are not enough, and there is little regularity and mechanism research. Lack of technology, less special feed; economical and applicable green prevention and control technologies for diseases, insects, weeds, and bird damage lack integrated innovation

Embodiment 1

[0019] A kind of rice-eel-shrimp-soft-shelled turtle co-production method comprises the following specific steps:

[0020] 1) Field engineering construction of paddy fields: Implementation location: Changshu City, Jiangsu Province, each paddy field covers an area of ​​10 mu, and the total rice eel farming area is 200 mu. Evenly excavate an incompletely closed circular fish ditch on all sides of the paddy field. The upper width of the ring fish ditch is 2 meters, the lower width is 1 meter, and the ditch depth is 80 cm (below the water level); 1 meter (above the horizontal plane); the unclosed part of the four sides is 8 meters, which is convenient for large machinery to enter and exit. The inlet and outlet are built with concrete, and barbed wire is erected to prevent animals from escaping, and 60 cm high hard calcium-plastic boards are placed around the field ridge as escape prevention boards. In the annular ditch, every 15 meters place a pile of circular large polyalgae, th...

Abstract

The invention discloses a method for integrated culture of rice-finless eel-crayfishp-trionyx sinensis. The method comprises the following steps: placing myriophyllum aquaticum in a ring-shaped ditchof a paddy field; putting crayfish seedlings in April or August, putting trionyx sinensis seedlings and cipangopaludina cahayensis in May, and putting finless eel seedlings in late June to early July;performing feeding; and catching crayfish in early June or early October, and catching finless eels and trionyx sinensis in November to December. According to the method for integrated culture of therice-finless eel-crayfish-trionyx sinensis, ecosystem biodiversity of the paddy field is improved, cannibalism degree of the crayfish is reduced, requirement for live baits of the finless eels and the trionyx sinensis is satisfied; and the method has the advantages of higher biological diversity, easy catching, adequate supply of live baits, more stable culture yields, higher economic benefits, and the likes.

Description

technical field [0001] The invention relates to the technical field of combining agricultural planting and breeding, in particular to a method for co-cultivating rice-eel-shrimp-turtle. Background technique [0002] At present, my country's paddy farming area has reached about 2 million hectares, such as "shrimp and rice co-cultivation", "rice and soft-shelled turtle co-cultivation", "rice loach co-cultivation", "rice crab shrimp and fish co-existence", "paddy field raising ducks" and " Raising frogs in paddy fields, etc., especially rice and shrimp co-(continuous) cropping accounted for a large proportion, and achieved good results. However, the systematization, modeling, and quantification of rice-fishing cooperative farming are not enough, and there is little regularity and mechanism research. There is a lack of technology, and there are few special feeds; economical and applicable green prevention and control technologies for diseases, insects, weeds, and bird damage lac...
