(一)微生物制剂的使用方法1.培水。在鱼虾蟹放养前10天左右,用100倍复合微生物制剂稀释液均匀泼洒池塘,净化环境。放苗前3天,再用浓度为20毫升/立方米的复合微生物制剂稀涂泼洒水面,使水中的有益微生物种群形成优势种群,利于鱼虾蟹下塘就能够适应环境。2.调节水质。水质突变,虾浮游水面时,用复合微生物制剂1.5千克/亩拌2千克红糖水后进行全池泼洒。一般情况,每半个月用复合微生物制剂1～1.5千克/亩稀释后全池泼洒,具体视水质
(A) the use of microbial agents 1. Pei water. 10 days before the stocking of fish and shrimp crabs, with 100 times the dilution of composite microbial agents evenly spilled ponds, purify the environment. Three days before Fangmiao, the concentration of 20 ml / cubic meter of compound microbial preparation diluted sprinkle sprinkling water, so that the beneficial microorganisms in water form the dominant population, which will help the ponds to adapt to the environment. 2. Adjust the water quality. Water quality mutations, shrimp floating surface, the composite microbial preparation 1.5 kg / mu mixed with 2 kg of brown sugar water Quanchiposa. In general, every half a month with compound microbial preparation 1 ~ 1.5 kg / mu diluted Quanchiposa, depending on the water quality
