图2. 2015-2017年实验期间内蒙古荒漠草原生长季土壤含水量和土壤温度年际间变化(平均值+标准误差)。CKs、N、W、NW分别表示不加水和氮、加氮、加水、加氮加水。不同小写字母表示同一年度不同处理间差异显著(p < 0.05); 不同大写字母表示同一处理不同年度间差异显著(p < 0.05)。
Fig. 2. Changes in growing season soil moisture content and soil temperature, 2015 to 2017, in a Nei Mongol desert steppe (mean + SE). CKs, N, W, NW represent no addition of water and nitrogen, addition of nitrogen, addition of water, and combined addition of water and nitrogen, respectively. Different lowercase letters indicate significant difference between treatments in the same year at the 0.05 level; different uppercase letters indicate a significant difference between years at the 0.05 level.
