Impact of long-term continuous soybean cropping on ammonia oxidizing bacteria communities in the rhizosphere of soybean in Northeast China

Continuous cropping can be a serious problem in Chinese soybean production. This can result in yield reduction, root diseases, and changes in microbial community structure. We studied community structure, clone libraries, and abundance of ammonia oxidizing bacteria (AOB) in soybean fields there were in continuous soybean production for up to 17 years (SC17). Results showed that the potential nitrification rate (PNR) and amoA gene abundance of soybean in continuous cultivation for seven years (SC7) was 0.34 µg NO₃^? g^?1 and 4.71 × 10^?5 amoA gene copies/g dry soil, respectively. These values were lower than other treatments. Phylogenetic affiliation analysis based on blast results of amoA gene clone sequencing showed that the sequences belonged to seven clusters: Cluster 1, Cluster 3b, Cluster 3a.1, Cluster 3a.2, Cluster 9, Cluster 10, and Cluster 4. Correlation of AOB community compositions with environmental factors was performed using canonical correspondence analysis (CCA). Results indicated that the composition of AOB communities in maize–soybean (MS) rotation and continuous cropping of soybean for two years (SC2) were positively related to the PNR of soil, soil moisture, and soil total nitrogen content. Soybean fields continuously cropped for 11 years (SC11) and SC7 fields had AOB community compositions that were negatively related to these factors. The AOB community composition of SC17 was positively correlated to the soil total carbon content of soil. The results in this study indicate that the potential activity and abundance of AOB community in soil significantly changed after seven years continuous cropping compared to other continuous cropping intervals. Cropping systems have important effect on the diversity of functional microorganisms and associated nitrogen cycles.

Publications Exchange at the National Agricultural Library

ABSTRACT

A brief overview is provided of the policies, responsibilities, procedures and current projects of the Gift and Exchange Unit of the National Agricultural Library (NAL). Exchange operations which formed a part of the earliest library traditions of the U.S. Department of Agriculture now aid NAL in meeting the challenges of acquisitions operations which must adapt continually during an era of rapid technological change and stringent funding.

基于“食品营养学”一流课程案例资源库的建设

案例教学法是基于实践经验的探索性教学方法,对"食品营养学"一流课程的建设、培养学生创新能力、全面提升教学质量具有积极的推动作用。案例资源库是保证案例教学能否成功实施的关键因素,是决定一流课程教学质量和教学效果的前提和保障。案例资源库建设的总原则应结合一流课程"两性一度"建设标准,符合课程本身属性和教学对象特点,紧扣课程教学大纲,与教学目标和教学内容相呼应。
