Water use efficiency (WUE) provides a direct measure of the inextricable link between plant carbon uptake and water loss, and it can be used to study how ecosystem function varies with climate. We ana...
2023年10月7日,Nature plants在线发表了南京农业大学李姗教授团队题为“Improving rice nitrogen-use efficiency by modulating a novel monouniquitination machinery for optimal root plasticity response to nitrogen”的研究论文。该团队在水稻中鉴定到一...
2022年8月28日,南京农业大学耕作制度与农田生态课题组的最新研究成果“Temporal complementarity be tween roots and mycorrhizal fungi drives wheat nitrogen use efficiency”在New Phytologist上发表。该成果揭示了氮高效小麦品种在花前依赖根系吸收氮素而花后依赖丛枝菌根真菌(AMF)促进花前...

氮素是植物生长发育所需的大量元素之一,水稻是我国的主要粮食作物,水稻生产对氮的需求仅次于水,是构成水稻生长成本的主要部分。目前,水稻氮肥表观利用率只有39%,即施氮肥量的50%以上残留在环境中。因此,在保证产量不减的基础上如何提高氮肥的利用效率,减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。
We explored the relationship between tree growth, water use, and related hydraulic traits in Populus deltoides Bartr. ex Marsh.and hybrid clones, to examine potential trade-offs between growth and wat...
Drought has become a problem that is universally faced by global terrestrial ecosystems. Northeast China is located in a region sensitive to global climate changes, and one of the main impacts of clim...
The study compares the effects of: timer (‘Timer’) and soil moisture sensor-controlled irrigation on soilless lettuce; two volumetric water content (Θ) thresholds for irrigation (0.30 (‘Θ = 0.3’) and ...
Foresters frequently lack sufficient information about thinning intensity effects to optimize semi-natural forest management and their effects and interaction with climate are still poorly understood....
Six trials were conducted on sandy soils and muck soils in Hendry County and Palm Beach County, Florida, USA. Before planting cv. Caprice snap bean, plots were fertilized with different P applicat...
Forest’s net primary productivity (NPP) is a key index in studying interactions of climate and vegetation, and accurate prediction of NPP is essential to understand the forests’ response to climate ...
Understanding how the aboveground net primary production (ANPP) of arid and semiarid ecosystems of the world responds to variations in precipitation is crucial for assessing the impacts of climate cha...
Field experiment was conducted for one growing season (2012) in clay loam soil at the Experimental Farm of Faculty of Agriculture, Southern Illinois University at Carbondale (SIUC), USA on soybean cro...
Farmer differentiation has important implications for the efficiency of farmland use. Applying the model of DEA and Tobit, using the household survey data, this paper investigates the effects of the f...
Attitudes regarding traditional energy sources have shifted toward renewable resources. Specifically, short-rotation woody crop supply systems have become more prevalent for biomass and biofuel produc...
