所谓深层海水,是指海洋深处的水。它营养丰富,温度低,一般在1-9℃,清洁少菌。这是因为海洋深处几乎没有太阳光的射入,有机物分解的速度远远高于合成的速度。而在有机物大量分解的过程中,会产生极为丰富的含氮和磷的营养成分。所以,在距陆地5公里的范围内,离海面300米以下的地方,藏有大量的这种深 The so-called deep sea water refers to the depths of the ocean water. It is nutrient-rich, low temperature, usually 1-9 ℃, clean bacteria. This is because there is almost no penetration of sunlight into the depths of the ocean, and decomposition of organic matter is much faster than synthesis. In the process of mass decomposition of organic matter, it will produce extremely rich nitrogen and phosphorus nutrients. Therefore, within a distance of 5 kilometers from the land and below 300 meters from the sea, a large amount of such deep
