The selection of good rice and duck breeds and the cultivation of strong seedlings and youngsters are the basis for the expected results of co-education. In terms of rice, it is necessary to screen high-quality new varieties of early, middle and late rice with medium-to-upper plant height, moderate plant type distribution, fairly thick stems and leaves, strong tillers, and good resistance (including resistance to lodging, resistance to rice blast, etc.). Regardless of whether the seedlings are transplanted and transplanted in semi-dry seedlings or seedlings or live seedlings, they must be soaked, disinfected, and germinated according to the requirements for cultivating seedlings, and appropriate sowing should be conducted in an appropriate period, through shallow wet water, skillful fertilization, and mild chemical control.

The drakes grow fast and have fresh flesh. The duck has a high egg production rate. Secondly, to breed good ducklings, generally mastering the "grain soaking, egg hatching", after 25-26 days of hatching ducklings, should be in the indoor heating device (equipment) brooding room insulation feeding, feeding a small amount of dip Wet minced rice, crushed wheat, ground corn, and fine gluten meal provide clean drinking water (duck that is a waterfowl can feed only if water and feed are mixed). At the same time, some shallow containers are placed on the rear of the rearing room (shed), and the clear water is provided to provide ducklings with exercise and improve their 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. China Agricultural Network Editor
