白浆土这种特殊土壤,在我国北方分布较广,面积很大,仅黑龙江就有白浆土面积42万余亩,主要分布于三江平原地区。其特点是颗粒细小,粘重;冷浆,不易导热;水体浑浊,水色灰白;pH值低,氮、磷及有机物缺乏;硅酸盐多;铁、锰离子还原积聚等。由于其具有的特殊理化特性,使白浆土质池塘养鱼效果不佳。为充分利用我国这一重要土壤资源,我们采用生物方法,对白浆土质池塘进行了改良试验,并总结 Albic soil This special soil, widely distributed in northern China, a large area, only Heilongjiang have white mud soil area of ​​more than 42 acres, mainly in the Sanjiang Plain area. It is characterized by small particles, sticky weight; cold slurry, not easy to heat; water turbidity, aqua gray; low pH, lack of nitrogen, phosphorus and organic matter; silicate and more; Because of its special physical and chemical properties, so that the white soil pond fish farming is not good. In order to make full use of this important soil resource in our country, we adopt the biological method to improve the albacore pond
