Embodiment 1

[0020] The present embodiment provides a kind of method for raising fish in paddy field, concrete steps are as follows:

[0021] (1) Select a field: Select a field with sufficient water source, good water quality and no pollution, easy to fetch water for irrigation, and the cultivation layer is deep and watertight.

[0022] (2) Field block reconstruction: Excavate the fish ditch around the field and the cross-shaped central fish ditch at the 50 cm ridge around the fish-raising rice field. The fish ditch is 30 cm deep and 35 cm wide, and then dig at the intersection of the cross-shaped central fish ditch. A large fish pit with a depth of 1 meter and an area of ​​about 3 square meters is suitable for the habitat of fish. The fish ditch and the fish pit are connected to each other, and the fish farming rice field is divided into four independent areas, which are used as rice planting areas, and then the rice is planted. The soil in the area is plowed and about 600 kg of fermented...

Embodiment 2

[0028] The present embodiment provides a kind of method for raising fish in paddy field, concrete steps are as follows:

[0029] (1) Select a field: Select a field with sufficient water source, good water quality and no pollution, easy to fetch water for irrigation, and the cultivation layer is deep and watertight.

[0030] (2) Field block reconstruction: Excavate the fish ditch around the field and the cross-shaped central fish ditch at the 50 cm ridge around the fish-raising rice field. The fish ditch is 45 cm deep and 50 cm wide, and then dig at the intersection of the cross-shaped central fish ditch. A large fish pit with a depth of 1 meter and an area of ​​about 4 square meters is suitable for the habitat of fish. The fish ditch and the fish pit are connected to each other, and the fish farming rice field is divided into four independent areas as rice planting areas, and then the rice is planted The soil in the area is plowed and about 600 jin of fermented farm manure per...

Embodiment 3

[0036] The present embodiment provides a kind of method for raising fish in paddy field, concrete steps are as follows:

[0037] (1) Select a field: Select a field with sufficient water source, good water quality and no pollution, easy to fetch water for irrigation, and the cultivation layer is deep and watertight.

[0038] (2) Field block reconstruction: Excavate the fish ditch around the field and the cross-shaped central fish ditch at the 50 cm ridge around the fish-raising rice field. The fish ditch is 40 cm deep and 40 cm wide, and then dig at the intersection of the cross-shaped central fish ditch. A large fish pit with a depth of 1 meter and an area of ​​about 4 square meters is suitable for the habitat of fish. The fish ditch and the fish pit are connected to each other, and the fish farming rice field is divided into four independent areas as rice planting areas, and then the rice is planted The soil in the area is plowed and about 600 catties of fermented farm manure p...

Abstract

The invention provides a rice field fish culture method, and belongs to the field of rice field fish culture. The rice field fish culture method includes the following concrete steps that a field good in water quality and free of contamination is selected, wherein a plowing layer of the field is thick and watertight; a fish ditch surrounding the field and a cross-shaped center fish ditch are dug in the field, a big fish pit is dug in the center fish ditch, a ridge is reinforced and heightened, a water inlet and a water outlet are dug, and a fish corral is arranged; rice seedlings are planted at reasonable density; fry of reasonable specification are put at reasonable density; artificial bait is put, pesticide and chemical fertilizer are used, the frequency and amount of water change of the rice field are managed; the water level change condition, food intake condition of fish and healthy condition of the rice seedlings are checked daily, and the emergency circumstance handling pre-arranged plan is made to respond to unforeseen circumstances conveniently in time and reduce property damage; the rice planting density and fish stock density are controlled reasonably, the rice-fish symbiotic relationship is set up artificially, so that resources are configured and used reasonably, and the rice yield and fish harvest yield are increased.

Description

technical field [0001] The invention relates to a method for raising fish, in particular to a method for raising fish in rice fields. Background technique [0002] Fish farming in rice fields is to raise fish on the water surface of rice fields. It can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn soil to promote fertilizer decomposition, and create good conditions for rice growth. Increase production by about 10%. Rice-fish farming should be based on rice and take fish into consideration. This guiding ideology is based on the theory of rice-fish symbiosis, using the artificially created symbiotic relationship between rice and fish to transform the original rice-field ecology into a more favorable direction, so as to increase rice production and fish production. Harvest purpose. At present, there is blindness in rice field fish farming, excessive pursuit of production, resulting in unreasonable planting and sto...
