明明是一缸清水,为什么养了鱼以后,水会变浑、发绿呢?原来,养鱼必须要喂饵料,鱼经过对饵料的消化吸收排出粪便,鱼粪中含有粗纤维、氨、氮等各类物质。因此,在营养物质丰富时,藻类便会大量生长繁殖,使水质变绿、变坏。为了避免藻类的大量繁殖,可以有目的地培养菌类替代藻类,让菌类大量增加,使水中没有更多的营养物质供给藻类,以抑制藻类生长,起到净化水质的作用。那么,如何培 Obviously a cylinder of water, why raise fish, the water will become muddy, green it? It turned out that fish must be fed bait, fish after digestion and absorption of food discharge excrement, fish manure contains crude fiber, ammonia, nitrogen And other materials. Therefore, when nutrients are abundant, algae will grow and multiply in large quantities, causing the water to turn green and deteriorate. In order to avoid the large-scale reproduction of algae, it is possible to purposely cultivate fungi to replace algae and increase the number of fungi so that no more nutrients are supplied to the algae in the water to inhibit the growth of the algae and to purify the water quality. So, how to cultivate
