摘　　要：分别将木质素、腐植酸与磷酸盐混合后,制备出新型的活化磷肥,研究其对玉米生长的影响。结果表明,新型活化磷肥可促进玉米的生长,施用木质素型活化磷肥的玉米在叶宽、茎粗、株高等性状上均优于其他处理组,玉米生物量达8.2 g/盆,吸磷量达1.46 mg/盆,磷素利用率最高,达0.18%,土壤磷素固定率明显较低,低于60%,磷素持续活化效果明显,能使土壤保持较高的有效磷含量。The effects of activated phosphorus fertilizers which is produced by mixing lignin, humic acid with phosphate respectively on the growth of maize are studied. The results show that activated phosphorus fertilizers can promote the growth of maize, the treatment with lignin activator is better than the other treatment groups in main maize growing characters such as leaf width, stem diameter and plant height etc., the biomass and phosphorus uptake with lignin activator application are the largest, respectively up to 8.2 g/pot and 1.46 mg/pot, and phosphorus utilization efficiency is the highest, up to 0.18%, the fixed rate of phosphorus in soil with lignin activator application is significantly lower than the other treatment groups, less than 60%, the sustained activation effect of phosphorus is obvious and can keep the high effective phosphorus content in soil.
