(一)杀灭清泥苔一般用生石灰清塘,草木灰或硫酸铜泼洒法。生石灰清塘只能在放养前使用;硫酸铜的有效用量则有争议;草木灰每亩需100斤,在生产中应用困难较多,实际难于满足,且草木灰、硫酸铜在杀灭青泥苔的同时也杀死大量的浮游生物,导致缺氧。我们根据何晏开的有关报道,进行了用青蒿培水杀灭青泥苔的试验,取得了良好效果。方法是每亩用100斤以上的青蒿,堆于池周四角的水面下,三天后,每天翻动一次,使腐烂分解的液体向池中扩散,随着水质逐渐变肥,青泥苔逐渐死亡,一周后全部被消灭。
(A) to kill clear mud generally with clear lime Qing Tong, ash or copper sulfate sprinkle law. Lime clear pond can only be used before stocking; the effective amount of copper sulfate is controversial; ash need 100 pounds per mu, more difficult to apply in production, the actual difficult to meet, and ash, copper sulfate in the killing of algae moss At the same time also kill a large number of plankton, leading to hypoxia. According to the relevant report of He Yan, we carried out the experiment of killing the algae moss with the water of Artemisia annua and achieved good results. Method is to use more than 100 pounds per acre Artemisia annua, piled in the pool at the corner of the water surface, three days later, turning once a day, so decomposed liquid spread to the pool, with the water gradually become fat, green mud gradually died After a week all were eliminated.
