中国椰子寒害及其对策研究

椰子是一种典型的热带作物，受低温天气影响椰树会出现严重的落裂果、叶片变黄甚至整株枯死的现象；大灾之后，各地采取了一系列抗灾救灾措施，并取得了明显成效。本文对受2008年初椰树寒害的区域性、品种耐寒性进行回顾，对3年来的抗寒救灾措施进行全面总结，并对今后中国椰子生产发展提出可行性建议。     

高校图书馆人才危机及其对策

随着信息技术的发展和人们信息需求水平的提高,高校图书馆的人才危机也发生了变化,主要体现为高校图书馆馆员有限的能力与读者日益提高的信息需求水平的矛盾。这是由于高校图书馆馆员偏低的学历层次、不合理的学科结构以及较低的工作积极性所造成的。对此,提出了诸如建立有效的交流机制、激励机制、人员流动机制以及提升馆员学历层次等办法及建议,来缓和这一矛盾。

Mechanisation of organic fertiliser spreading,choice of fertiliser and crop residue management as solutions for maize environmental impact mitigation

The environmental impact of crop production is mainly related to fossil fuels consumption and to fertilisers application. Emissions arising from the spreading of organic and mineral fertilisers are important contributors for impact categories such as eutrophication and acidification. The choice of the fertilisers and of the spreading techniques as well as the crop residues management can deeply affect the environmental impact related to crop cultivation.In this study, seven scenarios describing fertilising schemes characterised by different organic and mineral fertilisers and by different mechanisation were compared. The aim is to evaluate, using the Life Cycle Assessment (LCA) method, how the environmental performances of grain maize production were affected by these different fertilisers schemes. The study was carried out considering a cradle to farm gate perspective and 1 t grain maize was selected as functional unit. Inventory data were collected on a farm located in Po Valley (Northern Italy) during year 2013 and were processed using the composite method recommended by the International Reference Life Cycle Data System (ILCD). The compared scenarios involved organic and mineral fertiliser distribution and were: pig slurry incorporation after >3 days after spreading (BS), fast pig slurry incorporation within 2 h from spreading (AS1), direct soil injection of pig slurry (AS2), pig slurry incorporation (after >3 days) with straw collection (AS3), digestate spreading instead of pig slurry (after >3 days) (AS4), only mineral fertilisers (i.e. urea and superphosphate) distribution (AS5) and only mineral fertilisers (i.e. calcium ammonium nitrate and superphosphate) distribution (AS6).The results were not univocal, since climate and soil conditions as well as physical and chemical fertiliser characteristics differently affected the environmental load, especially for particulate matter formation, terrestrial acidification and terrestrial eutrophication impact categories. AS1 and AS2 showed the most beneficial results for these impact categories (between ↙67% and ↙73% respect to worst scenario). AS6, on the opposite, showed the highest environmental impact for those impact categories mainly affected by energy and fossil fuel consumption (climate change, ozone depletion, human toxicity with carcinogenic effect, particulate matter, freshwater eutrophication, freshwater ecotoxicity and mineral, fossil and renewable resources depletion), categories on which AS3 and AS4 were the best solutions. AS3 was the most impacting for terrestrial acidification and eutrophicationA sensitivity analysis was carried out varying grain maize yield (mostly affected: marine eutrophication) and ammonia volatilisation losses due to organic fertilisers (mainly affected: terrestrial acidification and eutrophication).The achieved results can be useful for the development of ⬓spreading rules⬽ that drive the application of organic fertilisers in agricultural areas where there is an intense livestock activity.

高校辅导员在学生管理中如何防范法律风险

辅导员是学生在校学习期间的管理者和责任人,学生在校期间发生法律纠纷都与辅导员有着间接关系。在传统的高校学生管理过程中,辅导员只是强调了自身对学生的管理权,却忽略了自身可能承担的法律风险,很容易成为法律风险的承担者。随着社会法律体制的不断发展和完善,人们对法律的理解也越来越全面,对法律责任的追究也越来越熟悉,所以在高校学生管理过程中,辅导员应该加强学生管理,提高自身的法律意识,将学生管理的法律风险降到最低。
