Techniques of raising Duck in Paddy Field

Duck breeding in paddy field is a key technology of organic rice production, a comprehensive and environment-friendly ecological agricultural technology, and a supporting technology combining planting and breeding. Without chemical fertilizer and pesticide, ducks can eat weeds and pests in rice fields, massage and loosen soil, produce muddy water and fertilize fields, and produce pure pollution-free rice.

Site Settings

Take 1 mu (rice area 634 square meters, duck house and activity site 33 square meters) as an example, first use plastic mesh to enclose 1 mu area into 80~100 cm high net wall, the mesh size is suitable for ducks over 10 days old. Then draw 33 square meters of open space in any corner of the rice field, and use the same net to make the surrounding area good, leaving only a small door 50 cm wide towards the center of the field, so that the open area can form an independent field, and the overall height is not less than the ridge. After the site is filled and fenced, 12 square meters of it will be used to build a simple duck house to ensure that there is no wind or rain and to prevent rats and other animals from entering. The other 21 square meters will be used as a duck activity site.

variety selection

Select medium and small duck varieties with strong vitality, adaptability and stress resistance, such as Binhu duck, Jianchang duck, etc., to adapt to the characteristics of rice cultivation, so that ducks can freely pass through rice fields. A cross between mallard duck and domestic duck is available. At the same time, we should do a good job of epidemic prevention. Duck viral hepatitis oil emulsion vaccine should be injected before feeding, duck plague vaccine should be injected subcutaneously before stocking, so as to improve disease resistance and survival rate of ducklings.

rice-duck farming

1. Rice cultivation: For example, single-cropping rice can be cultivated in early May and transplanted in early June. Before transplanting, 2000kg decomposed organic fertilizer and 12~ 18kg ternary compound fertilizer were applied per mu. Rice does not need to apply pesticide to control insects and weeds in the whole growth period, only on the fifth day after transplanting. 7.5 kg urea per mu was applied once. Usually always maintain a water layer of 3~6 cm (except 7 days before harvest), in order not to expose mud as well. In the field, some snails and more duckweed and other aquatic animals and plants that reproduce and grow quickly should be stocked so that ducks have enough feed sources.

2. Duck breeding: 2 days before rice transplanting, 50 ducks per mu shall be bred. The returned ducklings were first carefully reared in an open enclosure at Tin Kok for 10 days. On the seventh day after rice transplanting, ducks were driven down to the field and allowed to forage freely for weeds and pests in the rice field. According to the amount of feed required by ducks, supplementary feeding shall be carried out in due time. Generally, ducks shall be driven into pens at the time of supplementary feeding, and the time shall be arranged from 3:00 p.m. to 5:00 p.m., or grain feed can be directly scattered into a certain area of the field, so that ducks can loosen soil to promote rice growth while looking for food. When ducks are formally fed with rice every day, they should be put down before 8:00 a.m. every day, driven back to the pen at about 5:30 p.m., and allowed to rest in time.

3. Crop arrangement: Light and small meat ducks can reach the standard of listing after 2 months of breeding. Generally, at least 2 batches can be raised in single-season rice field, and at least 3 batches in double-season rice field. In the process of succession, we should do all in and all out. And strictly disinfect the empty pen house, can obtain better income.

Note: In the heading stage of rice, ducks should be transferred to open pens to prevent duckbills from eating tender ears and causing rice yield reduction. At the same time, it is more suitable for large-scale popularization and use, which is beneficial to building houses beside the fields, planting rice and raising ducks by special personnel, and preventing artificial loss of ducks.
