Nitrogen Deposition Enhances the Positive Contribution of CO2 Fertilization to China’s Carbon and Water Use Efficiencies
نویسندگان
چکیده
With climate change, Nitrogen deposition (ND) and carbon dioxide (CO2) have increased significantly, but the effects of ND CO2 fertilization on carbon-use efficiency (CUE) water-use (WUE) are still unclear. Therefore, CUE WUE studied by means trend analysis partial derivatives. The results show following: (1) From 2000 to 2020, mean in China was 0.533, 1.235 g C kg−1 H2O. (2) In study area, a 53.8% 61.8% showed an upward trend, enhanced positive contribution 15.9% 19.3%, respectively. (3) explained 48.1% 56% increase WUE, respectively, 45.8% 50.1% increases (4) areas dominated accounted for 43.9% 12.7% total highlighting importance driving mechanism WUE. research helpful further

Nitrogen (N) deposition and its ecological effects on forest ecosystems have received global attention. Plantations play an important role in mitigating climate change through assimilating atmospheric CO2. However, the mechanisms by which increasing N additions affect net ecosystem production (NEP) of plantations remain poorly understood. A field experiment was initialized in May 2009, which in...
متن کاملSoil mulching significantly enhances yields and water and nitrogen use efficiencies of maize and wheat: a meta-analysis.
Global crop yields are limited by water and nutrient availability. Soil mulching (with plastic or straw) reduces evaporation, modifies soil temperature and thereby affects crop yields. Reported effects of mulching are sometimes contradictory, likely due to differences in climatic conditions, soil characteristics, crop species, and also water and nitrogen (N) input levels. Here we report on a me...
