传统上,一般在鱼类下塘前10—15天对鱼池进行清塘消毒,在鱼下塘前5—7天施有机肥培肥水质。这种作法虽然能保证鱼下塘后有充足的饵料供应,但却不能防止鱼病的发生。因为在施有机肥时,池水中药物毒性已大大降低,而有机肥中带有许多病原体,这样就使清塘消毒失去了意义,达不到预期的目的。笔者认为,肥水和清塘应该同时进行,先施入适量的有机肥,紧接着带水清塘,用生石灰或漂白粉等药物消毒。这样
Traditionally, fish ponds are generally cleaned 10-30 days before fish ponds, and organic fertilizer is used to fertilize the water 5-7 days before fish ponds. Although this practice can ensure sufficient supply of fish after ponds, it can not prevent the occurrence of fish diseases. Because in the application of organic fertilizer, the toxicity of water in the pool has been greatly reduced, and organic fertilizer with many pathogens, so that the clear pond disinfection lost its meaning, reach the desired goal. I believe that fertilizer and clear pond should be carried out at the same time, first into the amount of organic fertilizer, followed by water ponds, with lime or bleach and other drugs disinfection. such
