Abstract

Abstract:

This study reviewed the research on the drought resistance of Leymus secalinus and its application in ecological restoration, aiming to provide a scientific reference for the practical application and new variety breeding of L. secalinus. A combination of literature review and case analysis of ecological restoration practices was used in this study to elucidate the drought resistance mechanisms of L. secalinus from two aspects: physiological adaptive changes and morphological adjustments in tissue structure. It also comprehensively analyzed the unique advantages of L. secalinus in the field of ecological restoration by integrating its application techniques and patent achievements in vegetation recovery in sandy lands, slopes, degraded black soil meadows, and alpine grasslands. The results showed that L. secalinus had a high adaptability to ecological environments and could significantly increase vegetation cover under extreme conditions, thereby improving the ecological environment. Its rhizomes also played an important role in ecological restoration. However, the low seed-setting rate of L. secalinus currently severely restricts its large-scale application in ecological governance. Future efforts should focus on breeding L. secalinus to develop new varieties with high seed-setting rates, consistent traits, and stable yields. At the same time, new varieties with strong sexual reproduction capabilities should be cultivated to promote the large-scale application of L. secalinus in ecological restoration. This will provide a physical seed supply and technological support for desert control, saline-alkali land restoration, degraded ecosystem repair, and vegetation recovery in extreme environments.

Key words: Leymus secalinus, ecological restoration, drought resistance, sandy land, black soil meadows
