图3. 2013年和2014年生长季不同增水处理地下5 cm处土壤体积含水量(A, B)和土壤温度(C, D) (平均值±标准误差)。相同的字母代表增水处理之间最小显著差异(LSD)法多重比较结果差异不显著(p > 0.05), 不同字母表示处理间差异显著(p < 0.05), 其中2014年增水60%处理的温度值缺失。
Fig. 3. Soil volumetric water content (SVWC) (A, B) and temperature (C, D) at 5 cm depth under different water addition treatments in the growing seasons of 2013 and 2014 (mean ± SE). Same letters indicate a non-significant difference (p > 0.05) according to the least significant difference (LSD) test, and different letters indicate significant differences (p < 0.05) among treatments. Temperature data were not available for the water addition treatment of 60% in 2014.
