针对包头地区高寒、高碱度的特点,我们于1990年作了池塘主养鲤鱼创高产的试验。16亩试验池塘总产鱼10773公斤,平均亩产673.3公斤,其中鲤鱼总产9384.5公斤,平均亩产586.5公斤。每亩获纯利1488.4元。现将技术总结如下。一、鱼池条件及鱼种放养选东西向长,池深3米,有效面积16亩的池塘一口,配潜水泵一台,增氧机两台。4月25日以每亩2.5公斤漂白粉稍带水清塘,三天后注入井水和河水各半,水深1米,不施肥,并在鱼池向阳岸中间搭设2.5米高的饲料台。选杂交丰鲤为主养鱼种,鱼种用200ppm腐植酸钠洗浴20分钟。4月28日至5月1日放养鱼种,共28159尾,计2125公斤,平均每亩1759尾,132.8公斤。详见表1。
In view of the characteristics of alpine and high alkalinity in Baotou region, we made a trial of high yield of main carp in pond in 1990. The total output of 16 mu of test ponds is 10,773 kilograms, with an average yield of 673.3 kilograms, of which 9384.5 kilograms of carp are produced, with an average yield of 586.5 kilograms per mu. Net profit per acre 1488.4 yuan. Now the technology is summarized as follows. First, the fish pond conditions and species stocking Select east-west long, 3 meters deep pool, an effective area of 16 acres of a pond, with a submersible pump, aerator two. On April 25, with a bleaching powder of 2.5 kg / acre, a pond of clear water was taken. After three days of injection of well water and half of the river, the water depth was 1 meter without fertilization and a 2.5-meter-high feed table was set up in the middle of the fish pond. Selection of hybrid carp mainly fish species, 200ppm sodium humate bath for 20 minutes. From April 28 to May 1 stocking fish species, a total of 28,159, accounting for 2125 kilograms, an average of 1759 per acre, 132.8 kilograms. See Table 1 for details.
