一、常见病虫害的防治 (一)红圈病:是杆状的粘细菌所致,使藻块中央有红圈,颜色由黄至暗红。藻细胞的内含物逐步破坏而溶解,但异形胞仍存在。防治方法:发现初期可捻碎藻体,减少粘细菌对蓝藻的接触侵害。一旦发现有红圈病,可用1％石灰水清液或0.1ppm硫酸铜溶液或5％的波尔多原液快速喷雾防治。 (二)防治白化:因高温强光直射藻体,致使藻蓝素降解,而使藻体变白。因此,在高温强光条件下,用薄膜土池养藻,必须根据蓝藻生长繁殖的条件,季节和气候的变化情况,认真地进行人工控制调节。养藻必须要“勤检查,巧揭膜”。气温特高时要四面通
First, the common pest and disease control (a) red circle disease: sticky bacteria caused by the rod, so that algae central red circle, the color from yellow to dark red. The contents of algal cells are gradually destroyed and dissolved, but alien cells still exist. Prevention and treatment methods: found that the initial twisting algae can reduce the adhesion of bacteria to cyanobacteria sticky invasion. Once found red circle disease, available 1% lime water solution or 0.1ppm copper sulfate solution or 5% Bordeaux solution rapid spray control. (B) prevention and treatment of albino: direct sunlight due to high temperature algae, resulting in degradation of phycocyanin, leaving the algae white. Therefore, under the conditions of high temperature and high light, the culture of algae in thin-film soil ponds must be carefully controlled manually according to the conditions of growth and reproduction of cyanobacteria and the changes of seasons and climates. Algae must be “ground check, Qiao Jie film.” When the temperature is extremely high to pass
