方柱上大写字母表示同一处理年份间差异显著,小写字母表示同一年份处理间差异显著（P＜0.05）
Fig. 3. Readily desorbable phosphorus (RDP) of different treatments in black soils under long-term fertilization
Different capital letters above the bars indicate significantly difference among the different fertilizing years at the same treatment, and the lowercase letter indicated the difference among the different treatments at the same year (P＜0.05)
