池塘施肥养鱼在各地已经比较普遍了。利用人、畜粪便施肥成功地将鱼苗培育成夏花鱼种,已积累了丰富的经验。在鱼种和食用鱼饲养池塘里采用施肥的方法,节约人工饲料的投喂量,也取得了明显的增产效果。在池塘水体中,各类浮游植物借助太阳能进行光合作用,把从水中吸收的无机营养盐类和二氧化碳制成有机物,使自己不断生长繁殖,浮游植物被浮游动物、底栖动物等食用后,促进其生长繁殖,为鱼类提供了天然食料,形成了一定的池塘鱼产量。要使天然饵料生物持续生长繁殖,除了施足基肥之外,还需要不断追肥,以弥补水中各种营养物质,才能提高产量。池塘中施用各类肥料,又是怎样培养成鱼的天然食料呢?现就施用有机肥料的作用过程来说吧。有机
Fish ponds have become more common throughout the country. The use of man and livestock manure fertilization successfully fishes grow into summer flower species, has accumulated rich experience. In the fish species and fish feeding ponds using fertilization methods, saving the amount of artificial feed, but also achieved significant yield increase. In the pond water body, all kinds of phytoplankton use solar energy for photosynthesis, absorb inorganic nutrients and carbon dioxide absorbed from the water into organic matter, make oneself continue to grow and multiply, the phytoplankton is zooplankton, zoobenthos and other edible, promote Its growth and reproduction, providing natural food for fish, forming a certain amount of pond fish production. To make the natural food organisms continue to grow and reproduce, in addition to the Shizujifei, but also need continuous top-dressing to compensate for various nutrients in the water, in order to increase production. Pond in the application of various types of fertilizers, but also how to cultivate the natural food into fish? Now on the role of the process of applying organic fertilizers it. organic
