1水质调控随着养殖动物的生长,池塘中相对密度增大,水体残饵、排泄物、水草老叶腐烂,会消耗大量氧气,又会产生硫化氢等有毒气体,氨氮累积增多,pH值下降,极易造成浮头泛池。因此一要及时换水,少量多次,要吸取中上层水,以增加浮游生物种类,防止和减少蓝绿藻滋生形成“蓝淀水”。二要施用芽孢杆菌、光合细菌、硝化细菌、EM菌液等微生物制剂调控水质,以降低亚硝酸盐、氨氮、硫化氢、pH值过高等因素对水体造成的危害。秋季河
1 Water quality regulation With the growth of farmed animals, the relative density of the pond increases, the residual water, excrement, watery old leaves rot will consume a lot of oxygen, will produce hydrogen sulfide and other toxic gases, ammonia accumulation increased, pH decreased , Easily lead to floating pan pool. Therefore, a timely change of water, a small number of times, to learn in the upper water to increase the species of plankton to prevent and reduce the breeding of blue-green algae to form “blue water ”. Second, the application of Bacillus, photosynthetic bacteria, nitrobacteria, EM bacteria and other microbial agents regulate water quality, in order to reduce nitrite, ammonia nitrogen, hydrogen sulfide, pH and other factors over the water hazards.
