Paddy field fence duck is a new technology for ecological cultivation. It has obvious effects to control a certain number of ducks in paddy fields to control pests and weeds. It can reduce the cost of pesticides, improve the quality of rice hygiene, fertility, and economy. Social and ecological benefits are significant. The technical points are as follows. First, rice field selection and site preparation. Rice field ducks should select paddy fields with sufficient water sources, convenient drainage and irrigation, and fertile soil. After the paddy fields are leveled according to the requirements for high rice yield, good production ditch should be established around the field. Daejeon should also open the “Ten†ditch and then dig a depth near the cage. A water letter with a size of 2 square meters, about 30 centimeters, is used for ducks to take water and bathe. Second, duck species selection. Rice field fenced ducks should be selected for medium and small fine duck species with strong vitality, wide adaptability, good disease resistance, and strong wild food (this year, they are supplied by the Agricultural Technology Station). Third, the number of ducks. Generally about 15 ducks per mu, such as rice fields too large, a group of more than 80 should be reared in groups. Fourth, the fence building. Before transplanting rice, the application of nylon nets before the live larvae is used to keep the fields around well and prevent the ducks from escaping; a duck house is built in each hilly area for the ducks to rest (this year's agricultural technology station builds houses). Fifth, put the duck time. 12-15 days after the early and late rice seedlings were transplanted, and 10 to 12 days after the planting (after the rice had lived), the ducks were introduced into the field. The ducks affected the seedlings early, and it was too late to control the weeds. After the duck is put, any duck is free to move in the field, and it is generally not a duck in the middle. Sixth, duck field breeding technology. After the duck is put into the field, besides the free intake of the ducks, rice and corn should be fed every day, and the feed should not be too much or too little. Seventh, prevention and cure disease. Ducklings should be vaccinated in time with duck quail vaccine. The duck sheds and food hoppers should be kept clean. The duck sheds can be sterilized with 2% lime water, and the food pods must be sterilized with 25%. Eight, rice field management technology. Before going to the duck, according to the general high-yield cultivation and management of rice, ducks should maintain a 2-4 cm water layer for a long period of time. Generally no herbicides and highly toxic pesticides are applied. High efficiency and low toxicity should be selected for rice leaf roller and rice blast. Bio-pesticides are used for prevention and control (duck is temporarily confined for several days when applying pesticides); after harvesting ducks, wet and dry seeds are not dehydrated prematurely before maturity.
