Hippophae rhamnoides (family Elaeagnaceae) is a deciduous shrub that has become uniquely advantageous species in the arsenic sandstone area of Inner Mongolia due to its well-developed root system and strong tillering ability. This study, by taking 10-year-old H. as research object analyzing morphological traits their fine roots coordination within soil under different stubble heights (0, 10, 15, 20 cm) non-stubble treatment, aims select optimal height most conducive rejuvenation thus improve decline productivity this region. The results reveal significant differences properties (p < 0.05). Among traits, density shows highest total coefficient variation, making it sensitive trait. Principal component analysis indicate after center on high specific surface (0.316) + length (0.312), shifting toward resource-acquisition ecological strategy with best foraging efficiency observed 15 cm. Soil N:P C:P can explain 66% 61% strategies deployed during respectively. Fine exhibit adaptability breaking phosphorus limitation fixation carbon nitrogen.
