The key to the “three kinds of six cultures†technology for rice and duck co-cultivation is to grasp the following three stages: Seed and seedling stages: Selecting good rice and duck breeds, and developing robust seedlings and ducklings are the basis for whether or not co-culture can achieve the desired results. . For rice, it is necessary to screen high-quality new varieties with superior plant height, moderate plant type distribution, high stem diameter, strong tiller, and good stress resistance. For ducks, first of all, species suitable for stocking in rice should be selected, such as Shaoxing Ma duck, Hunan Lixian Ma duck, Fujian Jinding Ma duck and so on. These ducks are small and medium-sized, adult ducks weigh about 1.25-1.5 kilograms each, and they have flexible walking activities among stocking rice, and have small food intake, low cost, strong resistance to lodging, and wide adaptability. The drake has fast growth and fresh meat. Ducks have a high egg production rate. Second, in order to breed ducklings, we must master the "precipitation in the valley, egg hatching." Ducklings that have hatched from 25 to 26 days of shelling, due to low temperatures in early spring, should be kept in a brooding room with a warming device (equipment) and fed with a small amount of soaked minced, shredded, shredded corn, and fine gluten. Oh, provide clean drinking water. At the same time, some shallow containers are placed on the rear of the rearing room (shed), and the clear water is provided for the ducklings to make a splash and to improve the ducklings' adaptability to water. After 20 to 25 days after hatching, each duckling has a certain independent living ability when it weighs about 150 grams each, and it can be fed to rice. Co-development stage: Coordinating the fertility relationship between rice and duck is the key to the stage of rice-duck breeding. First of all, rice transplanting, ducklings stocking to be appropriate, seedlings returned to green after transplanting, about 10 days to start giving birth, this time you can put the ducklings in the rice groves, over wild life. In order to make the stocking ducks suitable for age, adaptability, high survival rate, and rapid growth, the fertilized duck eggs must be hatched in the incubator 28 days before the rice is transplanted or cast and then broadcast. After hatching, the young ducklings should be cultivated in the room for 10-14 days, and then stocked in the wild rice life. The stocking density of ducks must consider field feeds to ensure the growth and development needs of ducks. At the same time, it is necessary to consider that they can achieve better economic benefits. Generally, it is appropriate to use 12-15 per acre, preferably 100-120 individuals. This will not only help prevent the ducks from being over-clustered and stepping on the early rice seedlings, but will also allow the ducks to be distributed to all corners of the rice fields in order to find food and achieve more uniform control of field pests and weeds. When stocking ducklings, it is best to stock 3-4 1-2 week-old ducklings in a group of ducklings to serve as an early warning and leader when encountering foreign enemies. In order to enhance the disease resistance of ducklings, each duck before the stocking needs to be injected with vaccines to prevent duck plague. Harvest stage: After rice heading and grouting, the ear of the rice is drooping. At this time, it is necessary to try to drive the ducks out of rice. The method of catching ducks should be as simple as possible, without affecting the continued maturing of the grain that is not fully matured. Ducks can be listed for sale as meat ducks, and mother ducks can continue to raise eggs. In order to stagger the time-to-market of the ducks and obtain higher economic benefits, strict timetables for chickens and ducks to be raised and sold are also established: The first batch of meat ducks is held on March 6 every year, and the sale time is May. 12-15; The second batch of meat ducks will be held on April 15 and sold on June 10-13. The third batch of meat ducks will be held on June 18th. The sale time is August 20-25; Fourth batch of ducks will be reared on August 13th and sold around New Year's Day. The fifth batch will be held on August 5th and sold at the beginning of December. The catch time of the sixth batch of local chickens is September 7, and the sale time is December 25-30.
