Effects of NPK and ALA on endogenous hormones of Leymus chinensis (Trin.) Tzvel under drought stress
Grazing is the main utilization of native grassland, and forage fungal disease one limiting factors grassland productivity. The present research in Hulunber meadow steppe was conducted to investigate responses dominant plant Leymus chinensis (Trin.) beef cattle grazing, rust, their interaction influence. Six grazing intensity treatments with three replicates were established. response L. rust s...
Leymus chinensis is a primary plant in the meadow steppe and typical of China. With global warming increasing grazing intensity, grassland degradation being exacerbated. To better protect L. this area provide theoretical basis for restoring it, paper compared germinable seed bank soil germination characteristics (including initial time, duration germination, termination dynamics, index) free-gr...
The productivity of terrestrial ecosystems is limited by soil fertility, such assoil phosphorus (P). decomposition litter the main process that affects nutrient cycling. To understand characteristics and release under P addition, we conducted a 2-year bag experiment at addition rates (0–12.5 g m−2 yr−1). All decomposed faster during second growing season due to highly concentrated precipitation...
Nitrous oxide emissions during freeze/thaw periods contribute significantly to annual soil N2O emissions budgets in middle- and high-latitude areas; however, the freeze/thaw-related N2O emissions from waterlogged soils have hardly been studied in the Hulunber Grassland, Inner Mongolia. For this study, the effects of changes in land use/cover types on N2O emissions during freeze-thaw cycles were...
