The use of bio-fertilizers for fish farming in rice fields can improve resource utilization and land productivity, and increase farmers' income. It is a good form of developing ecological agriculture, but fish farming in rice fields must address the following three major contradictions.
The contradiction between shallow-irrigation rice field and fish farming: It is a good way to solve this contradiction by allowing fish to inhabit in fish ponds, fish pits, and shallow irrigation in rice fields. The fish ditch is 50 centimeters deep and wide, criss-crossing the rice field to form a "well". Fish pit area of ​​2 square meters, 1 meter deep, dug 1~2 per acre. Fish ditch and fish pit should be connected. Shallow irrigation, slow down the water when drying the field, so that fish have enough time to swim into fish ditch, fish pit. Shallow irrigation, during the sun should pay attention to observe the fish, find the fish floating head, immediately to the fish ditch, fish pit, add new water. Rehydrated in time after sun drying.
• The contradiction between topdressing and fish farming: The main method is to use organic fertilizer with appropriate amount of fungicide and apply base fertilizer. This is a good way to reduce the number of topdressing fertilizers and solve the contradiction between topdressing and fish farming. If the rice seedlings are small and grow weak and need top dressing, they must also control the quantity. Generally, farm manure can't exceed 150 kilograms per acre; topdressing ammonium phosphate does not exceed 10 kilograms per acre; topdressing superphosphate does not exceed 6 kilograms per acre. Rice fields should be deepened to more than 15 cm when topdressing. Note that the use of ammonium hydrogen phosphate is strictly forbidden in fish farming rice fields. The farmyard fertilizer must be completely cooked. The safe method is to thoroughly ferment the farmyard manure with a professional fertilizer starter.
Prevention of the Contradictions between Rice Diseases and Insect Pests and Fish Culture: After the co-culture of paddy fields and fish, the pests and diseases of rice are significantly reduced, and generally no medication control is required. If you really need to use drugs must use pesticides that are less harmful to fish, control the amount of drugs used, and use the correct method of drug use. Generally, low-toxic pesticides such as “Insecticideâ€, “Entrepreneurial Blightâ€, and “Potato Beggar†are used. When applying pesticides, the water of rice fields is deepened to more than 20 cm. When the morning dew is still dry, it is 45 degrees to the rice fields. Spray the medicine; change the new water immediately after spraying the medicine; when changing the water, arrange the irrigation along the side to avoid drying the dead fish.
