Abstract EN
Leymus chinensis is a perennial rhizomatous clonal plant with strong tolerance to mowing, grazing, drought, and salt-alkali.
However, with patchy soil environment, how mowing affect the photosynthesis of L.
chinensis in heterogeneous patches is largely unknown.
In this experiment, we tested the effects of mowing intensity (0, 35%, and 70% removal of aboveground biomass) on plant photosynthesis under different heterogeneous patches with different saline-alkali soil.
We found that moderate concentrations of salt-alkali under heterogeneous patches have no significant effect on the photosynthesis of L.
chinensis.
Moderate mowing can maintain photosynthesis under no heterogeneity soil and moderate salt-alkali patch condition.
In addition, heavy mowing and high salt-alkali soil under heterogeneous patches both inhibited net photosynthetic rate (PN) and transpiration rate (E), reduced leaf area, and plant height.
L.
chinensis responded to extreme soil conditions and strong disturbance by increasing water-use efficiency (WUE), reducing relative water content (RWC), and changing stomatal conductance (Gsw).
Therefore, our results imply that moderate grazing or mowing can be used to maintain the productivity and economic benefits of grassland when the soil heterogeneous patches with moderate saline-alkali conditions.
