What are the advantages and disadvantages of raising ducks in rice fields? Rice field duck farming technology points!

　　Rice duck farming is a good duck farming model, which can achieve the fruit effect of double benefit and double harvest, and can improve the quality of rice and duck meat products, which is loved by many farmers. However, before breeding, pay attention to the selection of rice fields and rice varieties. Today Xiaobian introduces the advantages and disadvantages of raising ducks in the rice field for everyone? Rice field duck farming technology points!

　　What are the advantages and disadvantages of raising ducks in rice fields?

　　1. Advantages

　　(1) Weeding. Ducks are constantly active in the rice field to feed, can remove weeds and green grass in the rice field, and can completely replace the organic rice field manual pulling. In the rice-duck co-cultivation experimental area of Yanling Town, Zhenjiang City, Jiangsu Province, the weed control rate in the rice field was more than 99.4%, and the weed control rate in the muddy water area where the duck could not enter was 76.3%, which significantly reduced the occurrence and harm of the dominant weeds in the paddy field.

　　(2) Deworming. Ducks are very fond of eating insects and aquatic small animals, which can effectively reduce pests such as rice planthoppers and longitudinal leaf borers in rice fields. In the experimental area of Yanling Town, the anti-removal effect of rice duck co-cultivation on rice planthoppers reached 79.9%, and the rice longitudinal leaf borer was 23.8%, and almost no blight occurred.

　　(3) Fertilization. During the rice-duck co-cultivation period, 1 duck lived in the rice field for 60 days, excreted about 15 kg of manure, and 15 ducks were stocked per 667 square meters (1 mu), which was equivalent to the application of 5.4 kg of urea, 17.5 kg of calcium, and 2.8 kg of potassium chloride, which basically met the topdressing of the paddy field.

　　(4) Shallow loose soil. Ducks are constantly active in the rice field, which plays a role in shallow loosening of soil and muddy water, making the paddy field soil loose, uniform, transparent and ripe, which can significantly reduce the volume quality of the soil layer and significantly increase the non-capillary lavity of the soil. The duck's stirring of water makes the oxygen in the air more soluble in the water and promotes rice growth. Stirring the soil creates muddy water, which can effectively inhibit the germination of weeds.

　　(5) Improve the quality of rice and duck products. Because organic rice does not use chemical fertilizers and pesticides, does not use herbicides, all kinds of insects and young grasses are more than ordinary rice fields, ducks in the rice field, prey on various insects, feed on young weeds and duckweed in the field, drink high-quality pollution-free water sources, is conducive to improving the quality of duck meat, breeding efficiency increases. The manure discharged by ducks in the rice field is used as an organic fertilizer for organic rice fields, and the rice produced is of good quality and taste.

　　(6) Promote the development of rice plants. Ducks are constantly moving between rice plants, and duck beaks are constantly looking for food on rice plants, which can promote plant opening and tillering, and promote rice plants to develop into short and strong fan-shaped plants, with thick stems, well-developed roots, large spikes, and strong resistance to wind and disease.

　　2. Disadvantages

　　Either way, arrangements should be made to recover the adult ducks in the field in time before the rice ripens. Because, at this time, the weight of the duck has generally grown to about 2 kg, the feeding ability is very strong, if it is not recycled in time, it will eat fast-ripening rice, resulting in a reduction in rice production. At this time, if there are individuals that cannot be listed, they should also be "transferred to the field" to prevent ducks from eating grain ears.

　　Key points of duck farming technology in paddy fields:

　　Venue settings

　　Taking 1 mu (rice area of 634 square meters, duck house and activity site 33 square meters) as an example, first use plastic mesh sheets to enclose 1 mu of area into a 80 to 100 cm high mesh wall, and the mesh size is appropriate for ducks over 10 days old to drill out. Then set aside 33 square meters of open space in any corner of the rice field, and use the same mesh pieces to surround the four sides, leaving only a small door 50 cm wide to face the center of the field, so that the open area can be independent and the overall height is not less than the field. After the site is filled in, 12 square meters of the site is taken to build a simple duck house to ensure that there is no wind and rain leakage and to prevent animals such as rats from sneaking in, and the other 21 square meters is used as a playground for ducks.

　　Variety selection

　　Select small and medium-sized excellent duck varieties with strong vitality, adaptability and stress resistance, such as Binhu hemp duck, Jianchang duck, etc., to adapt to the characteristics of rice cultivation, so that ducks can travel freely in the rice field. Hybrids of wild duck and domestic duck can be selected if conditions permit. At the same time, we must do a good job in disease prevention. The chicks should be injected with viral hepatitis oil milk vaccine before feeding, and then injected with duck plague vaccine subcutaneously before stocking, so as to improve the disease resistance and improve the survival rate of the chicks.

　　Rice duck co-breeding

　　1. Rice cultivation: If the single-cropping rice can be seedlings in early May and transplanted in early June. Before transplanting, 2000 kg of organic fertilizer and 12-18 kg of ternary compound fertilizer were applied per mu of base fertilizer. Rice does not need to be treated with pesticides and weeds throughout the growth period, only on the fifth day after transplanting. Apply 7.5 kg of urea once per acre. Usually, always keep the water layer 3 to 6 cm (except for 7 days before harvesting), so as not to expose mud. Aquatic animals and plants that reproduce fast, such as snails and more duckweed, should be stocked in the field so that the ducks have enough feed sources.

　　2. Duck breeding: 2 days before rice transplanting, according to the standard of 50 per mu. The ducks are first carefully reared in an open fence in the corner of the field for 10 days. On the seventh day after rice transplanting, the ducks are driven to the field and given free to forage for weeds and pests in the rice fields. According to the amount of duck material needed to carry out supplementary feeding in a timely manner, generally in the supplementary feeding time to first drive the duck into the pen, the time is arranged at 3 to 5 o'clock in the afternoon, you can also directly sprinkle the grain solid feed within a certain area of the field, so that the duck can loosen the soil while looking for food to promote rice growth. When the ducks are officially co-bred with rice every day, the ducks should be put down in the field before 8 o'clock every morning, and the ducks should be driven back to the pen at about 5:30 p.m. and allowed to enter the house to rest in time.

　　3, stubble arrangement: light and small meat duck breeding 2 months can reach the market standard, generally single-cropping rice field can raise at least 2 batches, double-cropping rice field is at least about 3 batches. In the process of stubble, it is necessary to achieve full in and all out. And strictly disinfect the empty fence to achieve better returns.

　　"What are the advantages and disadvantages of raising ducks in rice fields? Rice field duck farming technology points! "That's it! Note: During the rice ear extraction period, the ducks should be transferred to an open fence to prevent the duck's mouth from eating the young ears and causing the rice yield to decrease. At the same time, it is more suitable for the promotion and use of a large area, which is conducive to building houses next to the field, and the special person grows rice to raise ducks to prevent the artificial loss of ducks.
