First, the construction of rice fields: rice fields should not be too large, generally about 1.5 acres is appropriate. The rice fields cultivated in the area need to be well-built, and polyethylene nets or plastic sheets embedded in the inside of the pots to prevent muddy holes from escaping. Two barriers are built into the water inlet and outlet. Polyethylene mesh is used on the outside and metal mesh on the inside. Digging fish in a suitable size in the field. The fish may be square, round or irregular, or excavated in horizontal and vertical grooves. The width and depth of the fish are 30-40 cm. The area of ​​the fish slip or ditch accounts for the area of ​​the paddy field. 5-10%.
Second, seed stocking: Indica rice rotation breeding mode: After the harvest of early rice, drying field 3-4 days, per acre Sami glutinous rice, rapeseed cake 130 kilograms, the next day per acre Shi cooked organic manure about 250 kilograms, exposure For 4-5 days, let it rot and decompose, then store water, stocking and breeding. Rice bran is also used as a breeding method: it is generally stocked after transplanting. The stocking time of single-crop rice should be after the first cropping, and the rice stocking time should be after late rice transplanting. In general, 20,000 cm to 27,000 tails are planted in 3-5 cm length per acre.
3. Feed feeding: After the stocking of loach fish, the first month is fed with half of the mixed feed of animal feed and plant feed, once a day, and the amount of each feed is 3-4% of the total weight of the loach. After 1 month, topdressing once every 15 days, applying 100 kg of fermented organic fertilizer per acre, and feeding silkworm cocoon, rice bran, bean cake, rapeseed cake, animal waste, etc. The use of fertilizing and feeding in the fish pit is conducive to centralized catching.
4. Daily management: Check frequently for anti-escape facilities. The water level should be adjusted in time according to the needs of rice or alfalfa. Before watering, the rice should be properly shallow, so as to promote rooting of rice. Deepening the water level during the jointing stage of rice. In heavy rain, special care must be taken to prevent the muddy from escaping the field.
