Rice and duck breeding main supporting technology

First, choose a good variety of ducks should be suitable for selection of small and medium-sized individuals in paddy field breeding varieties, adult ducks each weighing 1.25-1.5kg, stocking rice through flexible activities, a small amount of food, the cost is lower, lodging strong resistance , Wide adaptability, high survival rate; rice should choose middle and upper plant height, moderate plant type distribution, fairly thick stems and leaves, strong tillers, good early and late rice varieties with good resistance. Second, the cultivation of duck ducks generally mastered the "grain soaking, egg hatching" in order to facilitate the transplanting of rice after the ducklings can be put into the rice in time for co-edication, so it must be done with ducklings as soon as possible to order jobs. Miao ducklings should be given a viral hepatitis vaccine 1-3 days old and supplemented with some antibiotics such as oxytetracycline and tetracycline. The duck plague vaccine was injected subcutaneously before stocking to improve the disease resistance of the ducks. We must carefully select stocking ducklings, choose spirits, liveliness, moderate hairiness, neat and bright ducklings, and achieve good individual duckling quality, high survival rate, and fast growth and orderliness in order to increase the collection of ducks. rate. 3. Appropriate stocking When the ducklings are 10-12 days old, they should be stocked in an area of ​​10-12 mu in order to prevent the ducks from being oversized and the rice seedlings from being damaged due to uneven feeding. Nylon nets or shade net fences (0.7-0.8m above the ground) are used around rice fields to prevent ducks from fleeing and suffering from natural enemies. The stocking densities are determined according to the conditions of foodstuffs, weeds, etc. in paddy fields, and are generally stocked in 12-15 stocks per acre, and stocked on the 15th after transplanting in paddy fields. After stocking, the rice field must take a small and easy shelter to facilitate duckling sheltering and feeding to increase the survival rate. Fourth, the amount of feeding in the rice breeding while the same time, should do a good job in the breeding of annatto, the establishment of a "bridge field" in order to continue to be thrown to the common breeding rice as an auxiliary feed for ducks. In the early stage of stocking, the ducks should feed some broken rice and other feeds in the morning and evening in order to adapt the ducks to the paddy fields. After 15 days of stocking, due to the abundance of foodstuffs such as fieldworms, grasses, and pods, the feed was not supplemented under normal circumstances to improve the duck's “fighting poultry” effect and promote the growth of rice. In the middle and late period, the reduction of live food such as rice straw and insects was reduced. In addition to the fact that the demand for increased food intake of ducks grows, in addition to continuing to throw albus, in the early evening, the ducks are properly fed with feed such as rice. The amount of feed generally increases with the growth of ducks, and the amount of supplementary feed needs to be gradually increased. Only duck 50-75g, to ensure that the long shelf and fattening of ducks on the nutritional requirements, so that ducks have better commercial and higher rate of meat out. Fifth, scientific management and co-cultivation Paddy fields do not generally require weed control pests. However, due to the long growing period of single-season rice and more pests, especially the damage of rice leaf roller in the upper part of the plant, when the duck can't work, it is necessary to use the pesticides that meet the pollution-free production requirements such as Ruijinte. The ducks are temporarily isolated. Due to the fertility of duck manure, the amount of nitrogen fertilizer in rice decreased by about 20%. The paddy field depth is suitable for the duck feet just touching the soil, and the rice paddy fields should be divided into rims. Ducks should maintain a water layer at the transition to ensure that the ducks need to bathe. During the symbiosis, it is necessary to regularly check the growth status of the ducks. Once dead ducks are found, they must be dealt with immediately and they should be prevented and treated in time according to the epidemic situation. 6. When the ducks are harvested in time and the sag droops, the ducks will feed on the full grains on the ear. Therefore, when the rice grains of the rice paddy are yellow or the ducks weigh about 1.5 kg, the ducks must be ducked. Drive out from rice fields, capture in time, and organize sales.
