摘　　要：试验结果表明,玉米施用楝素生物复合肥,每公顷1 500 kg为最佳施用量;在同样氮、磷、钾含量的情况下,楝素生物复合肥同常规三元肥、配方肥相比有一定增产效果,但效果不十分明显,不过施用复合肥能提高玉米的抗病虫能力、降解农药残留和重金属等有毒物质,是生产绿色玉米的理想肥料。The results of two experimental tests showed that： the optimum application dosage of chinaberry element biological compound fertilizer to the com is 1 500 kg per hectare; With the same content of nitrogen, phosphorus, and potassium, chinaberry element biological compound fertilizer has the effect not quite obvious to increase production compared to the general ternary fertilizer and formula fertilizer, but the application of fertilizer can increase the resistance to diseases and pests of corn, degradation of toxic substances such as pesticide residues and heavy metals. It is the ideal fertilizer for the green corn production.
