First, the sun Tianguan. Before the field is dried, it's important to clear the fish ditches to ensure they remain unblocked. When watering the field, do so slowly so that the fish have enough time to move into the fish ditches. During the drying period, maintain the depth of the fish ditch at 15-20 cm and the gill at 80-100 cm. Always keep an eye on the fish. If you notice them floating, immediately add fresh water to the ditch. After the drying process, be sure to refill the field with water promptly. Second, pesticide application. In fish and rice farming, it's crucial to use pesticides that are high in efficiency but low in toxicity and residue. Examples include trichlorfon, dimethoate, marathon, leaf glycosides, aldicarb, acephate, diterpenoid, leaf blight, and Jinggangmycin, which are relatively safe for fish. On the other hand, pesticides like fish toxin, toxaphene, sodium pentachlorophenol, and pyrethrum are highly toxic to fish and should be strictly avoided. Before applying any pesticide, drain the field water and guide the fish into the fish ditch. Close the inlet and block the field before spraying. It's best to divide the paddy into sections and apply pesticides sequentially, allowing the fish to avoid the treated areas. Use a fine mist spray, aiming directly at the rice leaves to minimize runoff into the water. Dusting should be done early in the morning when it's sunny, windless, and dewy, ensuring better adhesion of the pesticide to the leaves. If fish show signs of distress or become inactive due to the pesticide, replace the water immediately. Third, fertilizer application. When raising fish and growing rice, human waste must be fully composted before use. Apply no more than 150 kg per acre each time, and use chemical fertilizers in small amounts. The safe dosage per acre includes 7.5-10 kg of urea, 12.5 g of ammonium sulfate, 5-7.5 kg of potassium chloride, and 5-10 kg of superphosphate. Ammonium bicarbonate can be very harmful to fish and should not be used as top dressing. Always maintain a water depth of at least 15 cm when applying fertilizer to protect the fish population.
