保持适度水深早春鱼塘要保持适宜的养殖水位,不可过浅或过深。池水过浅,水体热能散失较快,而且初春天气变化频繁,若突然变冷,易冻伤池鱼;池水过深,由于春季气温偏低,光照不强,水温难以提高,不利于池塘物质能量转化和鱼类生长。实践表明,早春池水深一般以1.2米左右为宜,这样水体
Maintain appropriate depth Early spring fish ponds to maintain appropriate breeding water level, not too shallow or too deep. If the water temperature is too low, the water temperature is too low, the water temperature is hard to increase, which is unfavorable to the material energy conversion in ponds And fish grow. Practice shows that early spring pool water depth generally about 1.2 meters, so water
