In late March 1976, we conducted the application of waste sulfuric acid and furfural residue (plastic industrial waste) to treat the seedling soil in the Brigade of Taizihe Commune of Liaoyang City, East Malaysia Brigade of West Horse Bee Commune and Rice Plant of Sujiatun Province Test, and achieved good results for the control of blight rice blight, nurturing strong seedlings opened up a new way. First, the role and effect Waste sulfuric acid and furfural residue contain more sulfuric acid, with it to deal with the soil, adjust to moderate acidity, can make the soil in the blight of fungi inhibited, the seedling roots from damage and enhance seedling physical fitness, Eliminate the hazards of blight. According to the provincial experiment of rice in 1974, when the soil
