当前正是农闲时节,这是塘堰改造的大好时机。根据防洪、灌溉、养鱼对塘堰的要求,塘堰的改造主要进行以下几项工作。一、小塘改大塘,浅塘改深塘。如果条件许可,塘堰水面最好在2—10亩之间,水深在2.5米以上,这样既可以增加蓄水量,有利于抗旱防涝;又可以增加养鱼水体空间,提高鱼产量。二、挖出多余的淤泥用来作为农家肥料,既有利于对养鱼水质的控制,又有利于捕捞。三、加固池堤,防渗漏。随着塘堰的改大加深,对池堤的要求也相应提高,因此,对池堤要
The current season is slack season, this is a good opportunity Tangyin transformation. According to flood control, irrigation, fish ponds on the requirements of the transformation of pond weir mainly the following work. A small pond to Datang, shallow pond to change deep pond. If the conditions permit, the pond weir the best 2-10 acres, the water depth of 2.5 meters or more, so that it can increase the storage capacity is conducive to drought and waterlogging; but also to increase the space for fish farming and water to improve fish production. Second, excavated excess sludge used as a fertilizer for farmers, both conducive to the control of fish water quality, but also conducive to fishing. Third, strengthening the pool embankment, prevent leakage. With the deepening of the pond weir, the requirements of the pool embankment also increased accordingly, therefore, to the pool embankment to
