Embodiment 1

[0014] A method for cultivating fish in rice fields, including the following steps:

[0015] (1) Paddy field selection and pre-treatment: choose rice fields with convenient irrigation and hard ridges, set up water inlets and outlets, and set up anti-escape nets at the water inlets and outlets to further strengthen and heighten the ridges. The height of the ridges is 33cm. A 34cm deep fishing ditch was dug down from the inner edge, and farmyard manure was added to the rice field at a rate of 260kg per acre of rice field. Specifically, the farmyard manure was fermented from poultry manure, straw, hay and plant ash, and finally applied to the rice field. Introduce fresh water source inside; (2) Put fish fry: When the rice in the paddy field grows to 24cm, introduce fresh water into the paddy field again to ensure that the height of the water body in the paddy field from the top of the ridge is 13cm, and then raise 2900 fish per mu of rice field The proportion of the fish is put into...

Embodiment 2

[0017] A method for cultivating fish in rice fields, including the following steps:

[0018] (1) Paddy field selection and pre-treatment: choose rice fields with convenient irrigation and hard ridges, set up water inlets and outlets, and set up anti-escape nets at the inlets and outlets to further strengthen and heighten the ridges. The height of the ridges is 35cm. A 36cm-deep fishing ditch was dug down from the inner edge, and farmyard manure was added to the rice field at a rate of 290kg per mu of rice field. Specifically, the farmyard manure was fermented from poultry manure, straw, hay and plant ash, and finally applied to the rice field. Introduce fresh water source inside; (2) Put in fish fry: when the rice in the paddy field grows to 28cm, introduce fresh water source into the paddy field again to ensure that the height of the water body in the paddy field from the top of the ridge is 13cm, and then raise 2750 fish per mu of rice field The proportion of the fish is put in...

Abstract

The invention discloses a method for breeding fishes in a paddy field. The method comprises the following steps of rice field selection and early-stage treatment, wherein the paddy field which is convenient to irrigate and has hard ridges is selected, a water inlet and a water outlet are formed, and anti-escape nets arranged at the water inlet and the water outlet; fry putting, wherein when rice in the paddy field grows to 20-30 cm, a fresh water source is introduced into the paddy field again; breeding management, wherein duckweed is cultivated in the paddy field, the area of the cultivated duckweed accounts for 30-40% of the area of the paddy field, small fishes and small shrimps are put into the paddy field, and granular feed is put into the paddy field twice a day. According to the method, the growth speed of the fishes bred in the paddy field is increased through the reasonable arrangement of the processes such as paddy field selection and early-stage treatment, fry putting and breeding management, and no pollution is caused to the surrounding environment in the whole breeding process.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and particularly relates to a method for cultivating fish in rice fields. Background technique [0002] In order to improve the utilization of land resources, more and more people are cultivating fish in rice fields while planting rice. However, the irregularity of the breeding process has led to the slow growth of fishes cultivated in rice fields. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a method for cultivating fish in rice fields with fast fish growth. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a method for cultivating fish in a rice field, including the following steps: [0005] (1) Paddy field selection and pre-treatment: choose rice fields with convenient irrigation and hard ridges, set up water inlets and outlets, and set anti-escape nets at the inle...
