1.微囊藻。包括铜绿微囊藻和水花微囊藻,喜生长在温度较高(28～32℃)和碱性较重(pH值8～9.5)的水中,因此多在夏、秋季旺发。藻体死亡后,向水中释放大量毒素,对鱼类生长非常不利,甚至毒死鱼类。防治方法:①经常加注新水,不使水中有机质含量过高,注意水的pH值调节可控制微囊藻的繁殖。②对已发现有微囊藻的池塘,在形成初期可用0.7～10~(-6)硫酸铜全池泼
Microcystis Including Microcystis aeruginosa and Microcystis aeruginosa, hi grow in the higher temperature (28 ~ 32 ℃) and alkaline heavier (pH 8 ~ 9.5) of the water, so much in the summer and autumn flourishing. After the death of the algae, a large amount of toxins are released into the water, which is very unfavorable to the growth of the fish and even poison the fish. Prevention and treatment methods: ① often filled with fresh water, do not make the organic matter content is too high, pay attention to the pH value of water can control the growth of Microcystis. ② have found Microcystis pond, available in the early formation of 0.7 ~ 10 ~ (-6) copper sulfate Quanchiposa
