水肥耦合下西芹生育期内硝酸盐含量变化规律分析

为了探索水肥耦合对西芹生育期内硝酸盐含量的变化规律,采用三因素五水平二次通用旋转组合设计,在冀西北高寒半干旱区开展了旱棚试验研究.试验表明:随生育期延长西芹硝酸盐含量先升后降,且收获期最低:水肥高中低不同组合下西芹生育期硝酸盐含量除低肥低水和对照因缺水在收获前期有波峰出现外,其他水肥不同组合下,硝酸盐曲线均表现为先升后降.从卫生学角度评价,只有处理7(N109.5P36W5692)和处理20(N270P90W4500)即低肥高水和中水中肥处理西芹硝酸盐含量符合安全标准.不同因子组合下各效应(单因子效应、双因子效应及3因子效应)的西芹生育期硝酸盐动态变化规律表明,氮、磷、水对西芹硝酸盐主效应分析依次表现为增加、不确定性和减少.结果表明:不合理的氮、磷、水施用是限制西芹正常生长,造成西芹硝酸盐积累的主要原因.     

工程认证背景下模块式互动教学在《食品工艺学》创新实验中的应用

Modularly interactive teaching was introduced in the innovative experiment of food technology, through the combination of food additives, principles of food preservation and food technology. Experiment content was expanded without increasing class hours, considering both the crossing of the knowledge and the reasonability of the evaluation method. Generating the study enthusiasm of the students, improving the practical ability and understanding of the knowledge, fully accomplish the requirement of the engineering certification.     

Effects of landscape complexity on the ecological effectiveness of agri-environment schemes

Agricultural intensification is a major cause for biodiversity loss. It occurs at field scales through increased inputs and outputs, and at landscape scales through landscape simplification. Agri-environment schemes (AES) of the European Common Agricultural Policy (CAP) aim at reducing biodiversity loss by promoting extensification of agricultural practises mostly at field scales. We present a conceptual model for the relationship between landscape complexity and ecological effectiveness of AES based on (a) non-linear relationships between landscape complexity and abundance and diversity at field scales and (b) four possible interactive scenarios between landscape- and field scale effects on abundance and diversity. We then evaluated whether and how effectiveness of AES interacted with landscape-scale effects of intensification along a landscape complexity gradient established in central Spain. Pairs of cereal fields with and without AES but with the same landscape context were selected in three regions differing in landscape complexity. Effectiveness of AES was measured as differences between paired fields in species richness and abundance of five target groups (birds, grasshoppers and crickets, spiders, bees and plants). Landscape metrics were measured in 500–m radius circular plots around field centres. Positive, negative and no effects of landscape complexity on effectiveness of AES were found, suggesting that effects of complexity on effectiveness of AES changes from positive to negative along gradients of landscape complexity. Effectiveness of AES for improving biodiversity was then constrained by landscape. Compulsory measures aimed at enhancing or maintaining landscape complexity would enhance the effectiveness of AES for preserving biodiversity in farmed landscapes. For M.
