鸭为杂食性水禽,能充分利用农副产品和动物性饲料,所以鸭粪的肥效较高,利用鸭粪肥水养鱼,效果很好。若在渔场中养蛋鸭,则既可积肥,又是一项成本低、收入高的副业生产。据有关资料记载、每只鸭子年排泄量为60公斤。如养1000只鸭子,一年可积肥6～10万公斤,相当于15头猪的年排泄量。渔场鸭棚一般都在场的围堤附近分散搭建。长18米,宽5米的鸭棚可容蛋鸭1000只。其布局和放牧方式,一般有三种: (1) 鱼塘养鸭。鸭棚建在池的围堤附近,舍前有5米以上宽度的方形运动场,场前由一块大于30度的斜坡与鱼池相接。由于
Duck for omnivorous waterfowl, can make full use of agricultural and sideline products and animal feed, so the high efficiency of duck manure, the use of duck manure water fish, the effect is very good. If raising ducks in the fishing grounds, then both fertilizer, but also a low-cost, high income sideline production. According to the information records, each duck excretion of 60 kg. Such as raising 1,000 ducks, one year can be accumulated fertilizer 6 to 10 million kilograms, equivalent to 15 pigs in the annual excretion. Fish farm sheds are generally scattered around the dike to build structures. 18 meters long, 5 meters wide duck shed can accommodate 1000 eggs. The layout and grazing methods, there are three general: (1) fish ponds. The duck shed is built near the pond’s dike. There is a square playground with a width of more than 5 meters in front of the pond. The front of the pond is connected to the pond by a slope of more than 30 degrees. due to
