点和误差线分别代表响应比及其95%的置信区间,如果误差线没有跨越零线表示处理和对照存在显著差异;括号内的数值、百分数及字符分别代表样本数、施肥响应百分数和单位
Fig. 5. Effect of applying organic fertilizer on NUE under different climatic factors
Dots with error bars denote the overall mean response ratio and 95% CI, respectively. The 95% CI that do not go across the zero line mean significant difference between treatment and control. The value and percent in parentheses represent independent sample size and percent response to fertilization, respectively. NTM: Temperate monsoon climate, NTC: Temperate continental climate, STM: Subtropical monsoon climate, AAR: Average annual rainfall, MAT: Annual average temperature, ASD: Annual sunshine duration, FFP: Frost-free period
