含硝基腐植酸、DCD的氮肥增效剂对水稻生育性状及产量影响的试验研究

<正> 我国农业生产中的主要氮素化肥是尿素和碳酸氢铵。随着作物产量的提高,施用氮肥量也不断增加,但由于施入土壤中的尿素或碳酸氢铵分解速度快,有相当一部分氮素作物尚未吸收利用就流失或挥发而浪费掉。据测定,尿素中氮素利用率只有35％,碳酸氢铵氮素利用率仅15～25％。本试验结果表

尿素与DCD和有机物料配施条件下氮素的转化和去向

采用好气土壤培养试验 ,研究了尿素配施有机物料和DCD条件下土壤不同氮库的动态。结果表明 ,尿素、尿素与小麦秸秆、苜蓿秸秆、鸡粪配施的条件下 ,硝化作用在 7d之内完成。DCD处理的NH4 N一直保持较高水平 ,说明DCD对土壤硝化过程有强烈的抑制作用。与单施尿素相比 ,C N高的小麦秸秆显著地降低了NH4 N、NO3 N的含量 ;C N低的苜蓿秸秆和鸡粪显著地增加了NH4 N、NO3 N的含量。土壤易矿化有机态氮不仅含量低 ,且处理之间没有显著差异。与对照相比 ,施肥后土壤微生物氮的含量有所增加 ,但处理间没有达到显著水平。15N标记结果表明 :肥料氮的回收率在 84 .1%～ 92 .0 %之间 ,加入DCD显著提高了肥料氮的回收率 ,其他处理之间没有显著差异。DCD处理肥料氮主要以有机固定态或粘粒矿物固定态存在 ,其次以NH4 N形式存在 ;其他处理肥料氮在土壤中主要以NO3 N形式存在 ,加入秸秆增加了化肥氮被土壤固定的比例 ,鸡粪中的氮素几乎全部以极易矿化的形式存在。

Development and implementation of a new service delivery model for children with disabilities : implications for DCD

There is a general consensus that new service delivery models are needed for children with developmental coordination disorder (DCD). Emerging principles to guide service delivery include the use of graduated levels of intensity and evidence-based services that focus on function and participation. Interdisciplinary, community-based service delivery models based on best practice principles are needed. In this case report, we propose the Apollo model as an example of an innovative service delivery model for children with DCD. We describe the context that led to the creation of a program for children with DCD, describe the service delivery model and services, and share lessons learned through implementation. The Apollo model has 5 components: first contact, service delivery coordination, community-, group- and individual-interventions. This model guided the development of a streamlined set of services offered to children with DCD, including early-intake to share educational information with families, community interventions, inter-disciplinary and occupational therapy groups and individual interventions. Following implementation of the Apollo model, waiting times decreased and numbers of children receiving services increased, without compromising service quality. Lessons learned are shared to facilitate development of other practice models to support children with DCD.

Working with physical therapists to develop and evaluate an evidence-based online module for Developmental Coordination Disorder (DCD): bridging the knowledge-to-practice gap

Aims: Developmental Coordination Disorder (DCD) is a chronic condition with potential negative health consequences. Clinicians working with children with DCD need access to tailored, synthesized, evidence-based DCD information; however a knowledge-to-practice gap exists. The aim of this study was to develop and evaluate an evidence-based online DCD module tailored to physical therapists’ (PTs) identified needs. Methods: Guided by the Knowledge to Action framework, we interviewed PTs working with children with DCD (n=9) to identify their information needs. Their recommendations, along with synthesized DCD research evidence, informed module development. PTs (n=50) responded to scaled items and open-ended questions to evaluate module usefulness. Results: The module incorporated important PT DCD content areas including: 1) Identification; 2) Planning Interventions and Goals; 3) Evidence-Based Practice; 4) Management; and, 5) Resources. Case scenarios, clinical applications, interactive media, links to resources, and interactive learning opportunities were also embedded. PTs perceived the module to be comprehensive and useful and provided feedback to improve module navigation. Conclusions: Involving end-users throughout the development and evaluation of an online PT DCD module contributed to its relevance, applicability, and utility. The ongoing clinical use of this module may have the potential to improve the quality of PT DCD services.
