气候变化背景下济南市长清区干旱灾害风险评价研究

综合干旱类型,从致灾因子的危险性、敏感性、易损性及防灾减灾能力4个指标出发,分析气候变化背景下的山东省济南市长清区干旱灾害风险变化。结果表明,长清区干旱危险性分布特征总体表现为由西北向东南递减的趋势;干旱灾害孕灾体敏感性总体呈现出由西南向东北递减的趋势;干旱灾害易损性分布基本以行政区为单位,高易损性分布在除平安街道办事处外的西部地区;干旱灾害的防灾减灾能力总体呈现东北高、西南低的分布特征;干旱综合风险性呈现西南高、东北低的分布规律。     

On-farm evaluation of an active optical sensor performance for variable nitrogen application in winter wheat

Winter wheat (Triticum aestivum L.) represents almost 50% of total cereal production in the European Union, accounting for approximately 25% of total mineral nitrogen (N) fertilizer applied to all crops. Currently, several active optical sensor (AOS) based systems for optimizing variable N fertilization are commercially available for a variety of crops, including wheat. To ensure successful adoption of these systems, definitive measurable benefits must be demonstrated. Nitrogen management strategies developed based on small-scale plot research are not always meaningful for large-scale farm conditions. In 2010–2012 (5 site-years) on-farm study was implemented in northern Poland utilizing a strip-trial design. The objective was to evaluate the performance of AOS in combination with a built-in algorithm for variable N rate fertilization. In this study, the reference uniform N rates (farmer’s practice) were comparable to optimum variable N rate recommendations. Side-by-side comparisons of uniform and variable N application revealed inconsistent benefits in terms of grain yield, grain protein content (GPC), N use and N use efficiency (NUE). Anticipated yield increases and/or reduced N rates are typical drivers for AOS adoption. Significant yield increases are not easily attained on farms with winter wheat yields already close to maximum yield potential. Thus, sensor-based variable N rate recommendations for fields previously fertilized with relatively low uniform N rates would often entail more appropriate allocation (redistribution) of the same amount of total N. This would minimize N surplus in areas of lower productivity and to improve the sustainability of N management overall.
