图4. 不同单混播组合下盆、上盆土壤水氢稳定同位素比率(δD)(平均值+标准偏差)。16个土壤样品来自8个单混播组合的上下盆土壤。
AA、BB表示紫花苜蓿及斜茎黄耆单播, AC1、AC2、AC3与BC1、BC2、BC3分别表示比例为3:7、5:5、7:3的禾豆牧草混播组合。
Fig. 4. Soil water hydrogen stable isotope ratio (δD) in the bottom and upper pots of different combinations (mean + SD). Sixteen soil samples from the upper and bottom pots of eight single or mixed sowing combinations, totally.
AA and BB represent single sowing of Medicago sativa and Astragalus laxmannii, respectively. AC1, AC2, AC3, BC1, BC2 and BC3 represent the mixed sowing combinations of Medicago sativa and Astragalus laxmannii with gramineous forage in proportions of 3:7, 5:5 and 7:3, respectively.
