Rice and duck co-produced pollution-free production technology
Rice-duck co-produced pollution-free production technology is a low-input, high-output, advanced and environmentally friendly agricultural technology that produces pollution-free rice, duck, and duck eggs without using pesticides, fertilizers, and herbicides. The rice-duck co-production technique is after the seedlings are planted (7-10 days), and the warm-temperate ducks (7-10 days) are put into the rice field 24 hours a day until the rice is returned after heading and grouting. The symbiosis takes about 70 days. I. Implementation Procedures and Technical Essentials of the Rice-Duck Breeding Technique 1. Preparation of rice fields: Demonstration of paddy fields is best to choose flat and contiguous fields with adequate water supply. The paddy field should be kept at a water depth of about 15 cm. In particular, ducks should be able to catch floating mud when they are active, and do not need to put water to bake the field. If the technology is promoted in the first year, because duck dung may not keep up with the growth of rice, it is necessary to apply a certain amount of basal fertilizer. The seedlings are planted in the fertilizer bed and planted. It is recommended that the row spacing for planting be 20 centimeters and 30 centimeters. 2. Preparation of ducks: Ducks grow naturally in paddy fields and breeds must select duck species that have strong vitality, strong resistance, good sports, and eating wild animals and plants. According to the test results, local small and medium size ducks, hybrid ducks or soil ducks should be selected. If the duck body is too large, it is easy to overwhelm the seedlings. The duck is not good at activity and does not meet the requirements of the technology. The hatching time of the eggs is 281 days ahead of the planting time of the rice. The eggs are derived from healthy, high-yielding breeder ducks and must come from non-epidemic areas free from infectious diseases. 3. Preparation of protective nets and duck sheds: In order to prevent natural enemies from attacking and ducks scurrying in the fields, ducks must be provided with protective nets around the rice fields before they are put into the fields. - 0.5 meters can be a community every 5-10 acres. Protective nets generally use inexpensive plastic woven nets. If conditions permit, three thin wires are placed in the middle and lower part of the net. These wires are connected to the pulse current generator in the room. Once a natural enemy strikes, the pulsed current generator will send instant current (12 volts) to repel natural enemies. To protect young ducklings. At the same time, ducks cannot run freely. In addition, in order to prevent strong light and heavy rain, as well as to facilitate feeding, a 1-2 duck canopy was built in the corner of a rice field in each plot to provide ducks with rest, supplementary feeding, and shelter. 4, ducks into the rice fields: seedlings 7-10 days after the start of planting ducks, stocking density depending on the type of duck may be, usually 15-20/mu. The ducklings were placed in the pre-release area of ​​10-20 square meters in the corner of the duck canopy in front of the canopy duck canopy. The ducks were kept in the initial feeding area for 2-3 days before opening the portal of the initial placement area into the field activities. . In order to meet the needs of the initial duck for green feed, some duckweed plants can be put into the paddy field. 5. Field Management of Rice and Ducks: After the ducks are put into the rice fields, the field management of rice, including weeding, insect removal, cultivator and fertilization, is all given to the ducks. The thing to do is to regularly feed ducks every day. The feed for ducklings needs to be replenished 2-3 times a day for 3 weeks. After 3 weeks, depending on the situation, some duck feed supplements can be added every day or every other day, and some of the waste of agricultural and sideline products can also be supplemented. When feeding ducks every day, due to the large area of ​​the plots, shouting ducks is very difficult, and they can be domesticated with vocal horns. After domesticating, as long as the music is released, the ducks are quickly concentrated at the feeding place. 6. Activity and recovery of ducks: According to experimental observations, ducks are basically active in the field 24 hours a day, and there are 4 activity peaks every day. The activity time is 4:10-5:10 and 10:00-11:00 respectively. From 15:00 to 16:00 and from 18:30 to 20:00, the maximum amount of activity is especially around 4am. Because the ducks like to eat rice, the ducks will be withdrawn from the rice fields when they begin heading grouting. Second, a few issues that need attention Note the selection and breeding of rice and duck varieties that are compatible with the rice-duck symbiosis technique. Arrange the transition blocks. The rice-duck symbiosis technique requires the early propagation of ovum. After the late ducks are recovered from the paddy fields, they need to reare fertilizer for a certain period of time. Therefore, it is advisable to select paddy field blocks to grow lotus cultivars near the commensal field of rice and ducks, which can be used for early propagation and rear duck rearing. The rehabilitative establishments establish different models. At present, there are single and double rice crops in China, and two specific promotion models have to be explored. In addition, specific methods for setting the protective net can be determined according to the actual situation in the local area.
