Four homemade compound fertilizers with nitrification inhibitor dicyandiamide(DCD) being ratio 0%
1%
2% and 4%
separately were prepared out of common compound fertilizer by coating them with fly ash as major material.Soil incubation experiment and field experiment were used to study N-release characteristics of the fertilizers and their effects on Chinese cabbage.Results showed that:(1)Using four kinds of fertilizers could keep N as NH+4-N for a long time
