The North China District (NCD) is one of the main grain production regions in China. double cropping system irrigation has been leading to groundwater table decline at speed 1–2 m per year. Climate change leads uncertainty surrounding future NCD agricultural system, which will have great effects on crop yields and water demands. In this research, Meteorological dataset from 54 weather station sites over period 1960–2015 were collected quantify long-term spatial temporal trends meteorological...
Introduction: Tobacco, as a significant cash crop in China, warrants comprehensive investigation into the spatiotemporal dynamics of its carbon footprint order to address greenhouse gas (GHG) emissions and foster low-carbon, environmentally friendly agricultural practices. Methods: Employing life cycle assessment (LCA) methodology, this study aims scrutinize temporal variations across different functional units tobacco production China from 2004 2017, thereby elucidating composition key...
Abstract Water resources are the largest limiting factors for wheat ( Triticum aestivum L.) production in North China Plain (NCP). Irrigation used has caused a reduction groundwater table and aggravated regional water scarcity. In this research, we analyzed spatiotemporal changes winter cropping area balance during growing season overexploitation district (GOD) from 1985 to 2015. Focusing on typical districts, set different optimized scenes estimated water‐saving potential based current...
在盐分胁迫下筛选作物不同耐盐指标的适用性, 可为耐盐育种和分子标记辅助选择育种提供科学依据。为确定河套灌区向日葵的耐盐指标, 本研究以当地主栽品种'LD 5009'为研究对象, 2年共选择14个典型地块作为定位观测点, 分析向日葵产量、生物量、株高等12个指标对盐分胁迫的响应, 筛选随土壤饱和浸提液电导率(EC<sub>e</sub>)增加而减小的指标, 采用非线性最小二乘数值逼近法建立其随不同土层土壤EC<sub>e</sub>的S型耐盐方程。结果表明: 向日葵产量、生物量、株高、叶面积指数、花盘直径、叶片和茎秆K+含量随土壤盐分的增加而下降。其中, 0~20 cm土层EC<sub>e</sub>与生物量的耐盐函数决定系数最大; 盐分胁迫对向日葵叶绿素的合成影响不大; 盐分胁迫下, Na<sup>+</sup>含量逐渐增加, 而脯氨酸和SOD含量先增加后减小。因此, 盐分胁迫下生物量可作为河套灌区向日葵耐盐性分析的关键指标。
