Problems solved by technology

Crayfish farming in paddy fields has developed rapidly. Due to the unique biological characteristics of crayfish’s survival and growth, the yield of crayfish in paddy field farming is generally not high, which is far from meeting the needs of market consumers for high-quality commercial shrimp.

Embodiment 1

[0026] A kind of paddy field crayfish and broad-body golden leech symbiotic culture method, comprises the following steps:

[0027] Step 1: Time sequence arrangement for planting rice, crayfish and leeches: from harvesting rice in November of the current year to late March of the following year, drain the water stored in the rice field, thoroughly expose it to the sun, and pass 40 to 50 sunny days The natural sunlight treatment can kill the pathogens at the bottom of the paddy field and change the soil structure, which is conducive to the survival and growth of crayfish and golden leeches. From the end of March to the first ten days of June of that year, crayfish were mainly cultivated, and rice was planted from June to November, and wide-bodied golden leeches were cultivated at the same time, so as to realize the co-cropping of rice and wide-bodied golden leeches;

[0028] Step 2: Reconstruction of rice field engineering, excavation of "field-shaped grid"-shaped ditches in th...

Embodiment 2

[0036] Artificial feeding adopts self-made compound feed, and its composition raw materials are as follows: 165 parts of Sanhuang chicken powder, 55 parts of peanut germ, 28 parts of buckwheat flour, 13 parts of pig blood meal, 13 parts of duck blood meal raised in paddy fields, and 13 parts of duck blood meal raised in paddy fields, and geese raised in paddy fields. 13 parts of blood meal, 6 parts of dog bone meal, 8 parts of celery, 4 parts of cinnamon stick powder, 0.1 part of astragalus polysaccharide, 2 parts of sudan grass sprouts, 1.5 parts of sunflower seed kernel, 25 parts of fresh eel blood, 0.2 part of yeast, clam meat powder 8 servings, 7 servings of snail meat powder, and 22 servings of rice and shrimp comprehensive planting straw powder without pesticide residues.

Embodiment 3

[0038] Artificial feeding adopts self-made compound feed, and its composition raw materials are as follows: 170 parts of Sanhuang chicken powder, 50 parts of peanut germ, 30 parts of buckwheat flour, 10 parts of pig blood meal, 10 parts of duck blood meal in paddy field, 10 parts of duck blood meal in paddy field, and geese in paddy field. 15 parts of blood meal, 7 parts of dog bone meal, 5 parts of celery, 5 parts of cinnamon stick powder, 0.2 part of astragalus polysaccharide, 3 parts of sudan grass sprout, 2 parts of sunflower seed kernel, 30 parts of fresh eel blood, 0.5 part of yeast, mussel meat powder 5 servings, 5 servings of snail meat powder, 20 servings of rice and shrimp comprehensive planting straw powder without pesticide residues.

[0039] Using the method of the present invention, from 2012 to 2016, the 75-acre paddy field of the Lobster Economic Specialized Cooperative has carried out continuous cropping experiments of paddy rice crayfish wide-body golden leech...

Abstract

The invention discloses a rice field crayfish and whitmania pigra symbiotic breeding method. The method comprises the following steps: step 1, conducting planting and breeding time sequence arrangement on rice, crayfish and whitmania pigra; step 2, performing transformation of rice field engineering: digging matts-shaped ditches in the field; step 3, establishing a grass-rice mussel-spirillum ricefield composite ecological system to provide natural baits for crayfishes and whitmania pigra; step 4, performing crayfish culture and catching; step 5, coupling rice planting management and whitmania pigra culture; step 6, performing whitmania pigra fry stocking preparation and fry putting; and step 7, performing self-making of a whitmania pigra compound feed, and supplementing artificial feed to a self-made cunninghamia lanceolata bait casting device. According to the method, through continuous experimental exploration, the success of breeding the crayfish whitmania pigra in the rice fieldis achieved, although the yield per unit of the whitmania pigra is not high, the crayfish whitmania pigra can be bred in the contiguous rice field, and batch production of the crayfish and the whitmania pigra is achieved.

Description

technical field [0001] The invention relates to the technical field of paddy field culture of crayfish wide-bodied golden leeches, in particular to a symbiotic breeding method for rice field crayfish and wide-bodied golden leeches. Background technique [0002] Procambarus clarkii belongs to Arthrophyta, Crustacea, Crawfishidae, Procambarus genus, also known as crayfish, scientific name Procambarus clarkii (hereinafter collectively referred to as crayfish), its delicious meat, rich nutrition, popular among people Love is the main species of shrimp farming at present. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, artificial scientific breeding is used to meet market demand. Crayfish farming in paddy fields has developed rapidly. Due to the unique biological characteristics of crayfish’s survival and growth, the yield per unit area of ​​crayfish in paddy ...
