Embodiment 1

[0033] Raising fish in rice fields includes the following steps:

[0034] 1) Paddy field preparation: choose a paddy field with good water source conditions, sufficient water source, good water quality, convenient drainage and irrigation, good water retention, and deep plowing layer;

[0035] 2) Paddy field improvement: raise the ridge around the paddy field to 60cm, and hammer and tamp it; set fish ditch and fish pit in the paddy field; the fish ditch is connected with the fish pit; Fish ditch and center fish ditch are formed; described fish pit is arranged at the center of paddy field, and in the present embodiment, paddy field area is 1 mu, establishes 1 deep 100~120 cm, the fish pit of area more than 5 square meters; The fish ditch is a V-shaped ditch set on the inner side of the ridge around the rice field; in this embodiment, the V-shaped ditch is 45cm deep (under ground level) and 45cm wide; the central fish ditch is a "ten"-shaped central fish ditch;

[0036] 3) Prepa...

Embodiment 2

[0050] Fish farming in another paddy field, including all other steps in Example 1 except step 5) biosorption.

Embodiment 3

[0052] To raise fish in another paddy field, except for step 8) selection of stocking fish, step 9) disinfection of stocking fry, and step 11) feeding and management, the rest of the steps are basically the same as in Example 2.

[0053] Step 8) Select stocking fish species: Grass carp is the main choice, and carp and crucian carp are properly matched.

[0054] Step 9) Disinfection of stocking fry: Disinfect the stocking fry in 7-9mg / L bleach solution.

[0055] Step 11) During feeding and management, appropriate amount of chemical pesticides are applied.

[0056] The ecological rice produced by planting rice in the above three embodiments was tested, and the chemical pesticide residues, the content of heavy metals such as lead and cadmium, and the content of protein were detected as follows.

Abstract

The invention discloses an ecological fish farming method in a rice field, which comprises the following steps of rice field preparation, rice field transformation, fish farming facility preparation, rice seedling transplantation, biosorption, rice field disinfection, irrigation, fertilization, stocking fish seed selection, stocking fish fry disinfection, stocking and feeding management, wherein annular field fish ditches dug through the rice field transformation are V-shaped ditches arranged on the inner sides of ridges around the rice field; the biosorption utilizes a biosorption agent to adsorb heavy metal in rice field soil and irrigation water; and stocking fish seeds are selected from eight-beard catfishes. The invention further discloses rice produced by rice plants planted in the rice field using the ecological fish farming method. According to the method and the rice, an effective usable area of the rice field is increased significantly; pollution of the heavy metal such as lead and cadmium is reduced; integral benefits of fish farming in the rice field are improved; the ecological rice contains rich protein, more microelements such as iron, magnesium and calcium, and vitamin C, has no chemical pesticide residual, and is green and environment-friendly; and the content of the heavy metal such as lead and cadmium is very low.

Description

technical field [0001] The invention relates to a method for raising fish in a paddy field and the rice produced by the planted rice. Background technique [0002] Rice field fish farming refers to a production method in which rice and fish are grown in the same paddy field, so that the planting industry and aquaculture industry are skillfully combined. In a similar environment, the rice and fish are symbiotic and mutually beneficial, and a production method is used to improve the overall efficiency of the rice field. . The method for raising fish in rice fields in the prior art comprises the following steps: preparation of rice fields, transformation of rice fields, preparation of fish farming facilities, transplanting of rice seedlings, disinfection of rice fields, irrigation, fertilization, selection of stocking fish species, disinfection of stocking fish fry, stocking, and feeding management, wherein : Paddy field reconstruction is to excavate the fish ditch around the ...
