通过采样分析和３年多点大田及盆栽试验结果表明，硫磺渣含硫量丰富，所含有机磷化物具有与对硫磷乳油相近的杀虫效力。用于农田底肥施用兼具防虫保苗和肥田松土，促进农作物增产的双重效果。硫磺渣系以五硫化二磷为原料生产对硫磷广谱杀虫剂过程中排放的一种化工废料。因...
Through the sampling analysis and the field and pot experiment results of more than three years, the results show that the sulfur residue is rich in sulfur and the organophosphorus compounds contained therein have insecticidal efficacy similar to parathion EC. It is used for the dual effect of applying base fertilizer on farmland with pest control, seedling protection and loose cropland to increase crop yield. Sulfur slag is a kind of chemical waste discharged from phosphorus pentasulfide as raw material to produce broad-spectrum parathion pesticides. because...
