随着制糖生产的发展,糖厂排出的废物滤泥将会越来越多。一个日处理1000吨甜菜的糖厂,每天大约可排出滤泥100吨,年积累量近2万吨。如果对这些滤泥不加以利用,年年积累下去,不仅会大面积占地,也会污染环境。对于滤泥的利用,过去在国内报道很少。因此如何在农业生产上应用滤泥,是本试验所要解决的问题。经化验,滤泥含钙34％,有机质19.35％,全氮0.51％,全磷1.6％,水解氮3.2毫克/ With the development of sugar production, waste sludge from sugar mills will be more and more. A daily processing of sugar beet 1000 tons of sugar a day, about 100 tons of mud can be discharged, the accumulation of nearly 20,000 tons. If you do not use these mud filters, accumulated year after year, not only a large area, but also pollute the environment. For the use of mud, the past few reports in the country. Therefore, how to apply the filter mud in agricultural production is a problem to be solved in this experiment. After the test, the filter calcium 34%, 19.35% organic matter, total nitrogen 0.51%, 1.6% of total phosphorus, hydrolyzed nitrogen 3.2 mg /
