Rice field raising advantages 1. Without destroying the original ecosystem of rice fields and increasing the use of water resources, the effects of one-water use and one-site double harvest can be achieved, directly improving economic benefits. 2, the ecological effect is more prominent, mainly manifested as muddy can directly eat some of the harmful insects in the water, play a part of the biological control of pests, save pesticides, reduce food pollution. Mud hi inhabits the surface of the muddy soil on the bottom of the ground, and can breathe through the skin and intestines in addition to breathing. Loach is an omnivorous fish that likes to eat at night, feeding on insects, small crustaceans, young grasses and diatoms, cyanobacteria, green algae, yellow algae and zooplankton. Under the conditions of captivity, the plankton bait is fertilized by fertilization, and the residual bait and feces at the bottom of the pond can also be used as its foodstuff. Artificial feeding can also be fed with commercial feed, such as peanut cake, rice bran, bran, bean cake, silkworm cocoon powder, snail, scorpion, water silk scorpion, fish, poultry and livestock viscera. Loach is small, light, greedy, and can cause indigestion when it is full, affecting normal breathing and causing bloating. Loach is a warm-water fish. It is yellowish in rice fields. Its growth water temperature is 15-34 degrees, and the optimum growth water temperature is 24-30 degrees. When the water temperature drops below 5-6 degrees or above 35-36 degrees, it sneak into the mud 10-30 cm mud layer to sleep. Rice field construction In rice paddy farming, it is necessary to choose rice fields with sufficient water source, good water quality, 2-10 mu in area, and build an 80 cm high escape wall with cement or plastic plates, film, screens, etc. (into the mud 30 cm) around the paddy fields. A 20-centimeter-wide step was repaired along the field, 15 cm away from the top of the field. A “field†shaped ditch was dug around the center of the field, with a width of 50 cm and a depth of 50 cm. One inlet, one drain pipe and one overflow pipe are used, and the pipe mouth is intercepted by a fine wire mesh, and the drain pipe is usually sealed with cement. Stocking It is best to use squid from the original seedlings of the loach or from natural waters. It is required to be healthy, disease-free and harmless. The age is 2 years old, the female body weight is 15-25g, and the male body weight is 12g or more. In the second half of February, before the paddy field is filled with water, 75-100 kg of quicklime per acre is evenly sprinkled for cleaning and disinfection. Fermented pig manure 1000 kg per mu, the water is filtered into the field, the water depth in the ditch is 30-40 cm, and the water body is fertilized, and the transparency of the water is about 25 cm. After the seedlings are returned to the green, the seedlings of 3-5 g/tail size are placed in the range of 2-2.5 million tails, soaked for 10 minutes with 3% salt solution before stocking, and then inoculated into the field after disinfection. Feeding management 1. Fertilization In the process of breeding, in order to ensure the continuous plankton, it is necessary to apply organic fertilizer in a timely, small amount and evenly. Fertilize once every 10-15 days, using 150 kg of fertilizer per acre. In addition, according to the specific conditions of water color, about 1.5 kg of urea or 2.5 kg of ammonium bicarbonate per acre is applied to keep the water body yellow-green. 2, feeding Due to the high density of Tanaka loach, artificial feed should be fed, such as bean cake, silkworm cocoon powder, fly maggot, cockroach, snail, cockroach, slaughterhouse scrap, rice bran, bean dregs, rapeseed cake, bran, etc., to supplement natural bait. Insufficient. July-August is the peak season for loach growth. It requires 15% of silkworm cocoon powder, 10% of meat and bone meal, and 25% of bean cake. The daily feeding is 2 times, and the feeding rate is 10%. From September to October, plant-based feeds such as bran and rice bran are mainly used. They are usually fed once a day in the morning and afternoon, and the feeding amount is 2%-4% of the total weight of the loach. 2% in early spring and late autumn. Specifically, it is flexible according to the conditions of the loach feeding. Generally, after each feeding, it is appropriate to eat it within 1-2 hours. 3, water level control Water level control is extremely important. The actual water level above the field is generally controlled at more than 5 cm. Add new water at the right time, usually add water once every half month, and the water temperature should be properly deepened in the summer high season. 4, disease prevention Since loach is suitable for paddy field farming, there is generally no disease occurring during the breeding process. In order to prevent the occurrence of red skin disease, 10-20 grams of furanone bait is used every month, and 50 kg of feed is fed for 2-3 days. The whole pool is sprinkled with 10-15 kg of quicklime per acre per month. The pesticide application time in rice is generally 3-5 days before transplanting, or 5-7 days after transplanting, and the seedlings are prevented from being applied once. 5, daily management Check the anti-escape facilities twice, especially in the rainy days, and carefully check the loopholes. Prevent the invasion of natural enemies (such as water snakes, ducks, etc.), observe the activities of the mud and the feeding situation. Water influx of highly toxic pesticides such as methamidophos, chlorfenapyr, carbofuran and sodium pentachlorophenol is strictly prohibited. Fishing method One is to catch water. In the place near the nozzle, the net is spread, and the water is discharged from the water inlet. Because the mud has the characteristics of watering, the net is lifted and caught after a certain time. This method is suitable for water temperature of about 20 degrees, when the mud loves activities; second, the bait trapping, put the sauteed bran or bran in the bamboo cage, put the cage in the ditch and lure into the cage; the third is to catch the dry field Slowly drain the field water so that the loach is concentrated in the exposed area of ​​the ditch. The above is the rice paddy farming technology for your reference, and I hope to help you. Huinong School has more relevant agricultural technology knowledge. Continue to pay attention to Huinong School to answer questions during planting or breeding.
