Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding, and in particular to an eco-friendly, environment-friendly and energy-saving rice-duck-canal circulation co-culture method. Background Art

[0002] Traditional rice-duck co-breeding requires that ducks be kept in large rice fields from the time the rice seedlings emerge until the heading stage, allowing them to feed on weeds and pests in the fields and then be driven back to the duck house at night. However, this model is somewhat difficult to promote in practice, as shown in the following three points: (1) The spacing between rice seedlings increases, which reduces rice yields, affecting economic benefits and causing farmers to have difficulties in implementation. The rice-duck co-breeding model requires that the spacing between rice seedlings be around 30cm to facilitate the ducks' movement in the rice fields in the later stages. Many farmers use a sowing spacing of about 10-15cm. If the spacing between rice seedlings is increased and the sowing density is reduced, the rice yield will be affected. Many large-scale farmers are unwilling to reduce the rice planting density in order to implement rice-duck co-breeding. If the rice seedling planting density remains unchanged, it will be difficult for the ducks to go to the fields in the later stages. (2) The labor and time costs required are high. To ensure that the ducks are evenly distributed in the rice paddies, the paddies must be divided into units with nets, with each unit covering 10-15 mu. Approximately 200 ducks are placed in each unit, and duck sheds must be built around each unit for the ducks to rest at night. Both the nets and the construction of duck sheds require considerable investment in funds and manpower, which invisibly raises the entry threshold for this model. (3) The traditional rice-duck co-rearing model has a short breeding cycle and insignificant economic benefits. Each year, the rice-duck co-rearing cycle lasts from the planting of rice seedlings to the heading stage, with only one batch of ducks being marketed. The initial investment cost is not low. If a company that specifically purchases rice paddy ducks cannot be found to cooperate, the market price of ducks of the same breed will not differ much, and the investment and income are not proportional. Summary of the Invention

[0003] In order to solve the above-mentioned problems, the present invention proposes an ecologically friendly and energy-saving rice-duck-canal circulation co-cultivation method in which rice fields, ducks and canals form a recyclable, symbiotic, green and organic small ecosystem, which reduces labor and feed costs, solves the problem of aquatic weeds breeding in canals, and reduces the use of chemical fertilizers and herbicides in rice fields.

[0004] In order to solve the above technical problems, the technical solution proposed by the present invention is: an ecological, environmentally friendly and energy-saving rice-duck co-cultivation method, comprising the following steps:

[0005] Step 1: Build duck sheds on the ridges between the canals and rice fields; the duck sheds are equipped with fermentation beds and feeding areas;

[0006] Step 2: Use large nets on both sides of the rice field and the canal to demarcate the rice-duck co-culture implementation area. The net area on the rice field side is 50-100 mu, and a row of nets is built along the canal side;

[0007] Step 3: Hatch or purchase ducklings at a rate of 10 - 15 per mu, and raise them in the fermentation bed area of the duck shed for 10 days after they hatch.

[0008] Step 4: After 10 days, open the door on the side of the duck shed facing the paddy field, and release the ducks into the paddy field where the transplanted rice has survived for trial release and grazing for 15 - 20 days.

[0009] Step 5: After 15 - 20 days, in the morning, first release the ducks into the paddy field to forage for insects and weeds, and then open the door on the side facing the water channel to let the ducks enter the water channel to avoid the heat and feed on aquatic plants and algae.

[0010] Step 6: When the rice is in the heading stage, close the door on the side of the duck shed facing the paddy field, and only open the door on the side facing the water channel every day.

[0011] Step 7: After the rice is harvested, let the ducks enter the paddy field every day to forage for the remaining rice grains and the rice that has fallen and cannot be harvested.

[0012] Preferably, no rice transplanting is carried out within 20 m of the duck shed, which serves as the centralized water entry area for the duck flock.

[0013] Preferably, the top and sides of the duck shed are made of color steel tiles, and small doors are provided on both sides close to the paddy field and the water channel.

[0014] Preferably, the height of the perimeter net on the paddy field side is 1.2 - 1.5 m, and the material is selected from corrosion - resistant and anti - aging nylon net or polyethylene net to ensure the stability of the perimeter net throughout the breeding cycle and prevent the ducks from escaping.

[0015] Preferably, the height of the perimeter net on the water channel side is 0.8 - 1.0 m, and the material is selected from lightweight wire mesh that is easy to install and disassemble, which is convenient for adjustment according to the actual breeding situation and can also ensure that the ducks will not get lost.

[0016] Preferably, the fermentation bed area of the duck shed is paved with a mixture of rice husks, sawdust and beneficial microbial inoculants, with a thickness of 30 - 50 cm.

[0017] Preferably, during the growth process of the rice, in combination with the activities of the ducks, the usage amounts of chemical fertilizers and herbicides in the paddy field are appropriately reduced to reduce agricultural non - point source pollution and improve the quality of rice. The usage amount of chemical fertilizers is reduced by 20% - 30% compared with the traditional planting method, and the usage amount of herbicides is reduced by 50% - 70%.

[0018] Preferably, an automatic drinking device and an automatic feeding device are set in the feeding area inside the duck shed.

[0019] The advantages of the present invention compared with the prior art are as follows: The implementation period of rice-duck co-culture is extended. In the traditional mode, it is recommended to stop the meat ducks from entering the paddy field when the rice in the paddy field is in the heading stage, that is, the breeding ends. In the new mode, when the rice in the paddy field is in the heading stage, the ducks can be raised beside the canal until winter. After the time is extended, the number of batches of meat ducks can be increased from one batch to two batches. After the rice is harvested, the ducks are put into the field to forage. The remaining rice grains can be used as feed for the ducks, which not only reduces the waste of lodged rice and residual rice grains, but also reduces the probability of the germination of ratoon rice. The saved feed cost also greatly improves the economic benefits of farmers. The ducks feed on aquatic plants and plankton in the canal, saving feed and eliminating the cost of canal cleaning. The organic fertilizer can enter the field with the irrigation water, achieving multiple benefits with one action. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below with reference to the drawings.

[0023] Example 1

[0024] The specially designed duck sheds are concentratedly built on the ridge in the middle of the canal and the paddy field. No rice seedlings are transplanted within 20 m close to the duck shed, which is used as the concentrated water entry area for the duck flock. The implementation areas of rice-duck co-culture are demarcated by large nets on both sides of the paddy field and the canal respectively. According to the integrity of the farmland layout, the netting range on the paddy field side is recommended to be between 50 and 100 mu, and 10 - 15 ducklings are hatched or purchased per mu. The netting range on the canal side is to build a row of nets along the canal side to ensure that the ducks do not get lost. After the ducklings hatch, they can be introduced into the fermentation bed area of the duck shed for breeding. After being raised in the duck shed for 10 days, the door on the side of the duck shed close to the paddy field is opened, and the ducklings are released into the paddy field where the rice seedlings have survived and taken root for a trial release. After 15 - 20 days, in the morning every day, the ducks are first put into the paddy field to forage for insects and weeds; then the door on the side close to the canal is opened to let the ducks enter the canal to avoid the heat and feed on aquatic plants and algae. The ducks are released back and forth between the paddy field and the canal, making full use of natural resources and reducing the input of labor, feed and initial construction funds. When the rice is in the heading stage, the door on the side of the duck shed close to the paddy field is closed, and only the door on the side close to the canal is opened every day to allow the ducks to have a certain amount of activity and foraging time. After the rice is harvested, the ducks are allowed to enter the paddy field every day to forage for the remaining rice grains and the rice that cannot be harvested due to lodging, reducing the loss of the paddy field and extending the breeding period of the ducks in the paddy field. The ducks can be raised from the rice transplanting season in June until the end of November, and the number of batches of meat ducks is increased from one batch to two batches. While improving the quality of rice and reducing the aquatic plants in the irrigation canal, the economic benefits of meat duck breeding can be doubled.

[0025] Example 2

[0026] Special-designed duck coops are concentratedly built on the ridge between the water channel and the paddy field. No rice seedlings are transplanted within 20 m near the duck house, which is used as the concentrated water entry area for the duck flock. Large nets are respectively set up on both sides of the paddy field and the water channel to demarcate the implementation area of rice-duck co-breeding. The net is set according to the integrity of the farmland layout. The net range on the paddy field side is recommended to be between 50 and 100 mu, and 20 ducklings are hatched or purchased per mu. The net range on the water channel side is to build a row of nets along the water channel side to ensure that the ducks do not get lost. After the ducklings hatch, they can be introduced into the fermentation bed area of the duck house for feeding. After 10 days of feeding in the duck house, open the door on the side of the duck house close to the paddy field, and the ducks are released into the paddy field where the rice seedlings have survived and taken root for trial stocking. After 25 days, in the morning every day, first put the ducks into the paddy field to forage for insects and weeds; then open the door on the side close to the water channel to let the ducks enter the water channel to avoid the heat and feed on aquatic plants and algae. The ducks are released back and forth between the paddy field and the water channel, making full use of natural resources and reducing the input of labor, feed and initial construction costs. When the rice is in the heading stage, close the door on the side of the duck house close to the paddy field, and only open the door on the side close to the water channel every day to allow the ducks to have a certain amount of activity and feeding time. After the rice is harvested, let the ducks enter the paddy field every day to forage for the remaining rice grains and the rice that cannot be harvested due to lodging, reducing the loss of the paddy field and extending the feeding cycle of the paddy field ducks. The ducks can be raised from the rice transplanting season in June until the end of November, increasing the number of batches of meat ducks from one batch to two batches. While improving the quality of rice and reducing the aquatic plants in the irrigation canal, the economic benefits of meat duck breeding can be doubled.
