草木灰属碱性肥料,是一种优质的速效性钾肥。农村中的草木灰资源非常丰富,在鱼塘中经常施点草木灰不仅能调节、改善水质,还能防治鱼病,加速鱼类的生长繁育。一、调节酸碱度。一般情况下,鱼类生长的水质要求 PH 值在7.5～8.6之间,在此范围内鱼的生长速度快。据测试,没有清淤泥的池塘,PH 值在7.3～7.5之间,均不能充分满足鱼类的生长需要。试验表明,给水深1.5米的鱼塘每亩施入草木灰110～190公斤,水中的 PH 值上
Ash is an alkaline fertilizer, is a high-quality quick-acting potash fertilizer. Ash resources in rural areas is very rich in the ponds often applied ash can not only regulate, improve water quality, but also prevent fish diseases and accelerate the growth and breeding of fish. First, adjust the pH. Under normal circumstances, the water quality of fish growth requirements PH value between 7.5 to 8.6, in this range of fish grow faster. According to the test, no clear silt pond, PH value between 7.3 to 7.5, can not fully meet the growth needs of fish. Experiments show that the water depth of 1.5 meters of fish ponds into the plant ash 110 to 190 kg, the PH value in the water
