摘要:

青贮发酵是秸秆和牧草等生物质原料跨季节保存的一个重要手段,也是传统的动物饲料制作方法,加入添加剂对改善青贮发酵品质、有氧稳定性和利用价值具有重要作用。为深入了解国内外青贮添加剂的研究现状和研究热点,本文基于Web of Science核心合集和中国知网(CNKI)数据库,采用文献计量学理论和可视化分析技术,对2005-2020年全球有关青贮添加剂的研究文献进行分析,以期为科研人员确立研究方向、开展科学研究和了解领域热点提供帮助。结果表明,全球有70个国家(地区)、965所研究机构开展了有关青贮添加剂的研究,相关成果发表在187种期刊上,跨区域合作较为频繁。美国、巴西、加拿大和中国等国家表现出较大的研究体量和较强的合作关系,美国和加拿大学者发表的文献篇均被引频次和受关注度较高。该领域研究成果报道主要集中在畜牧业、农业、兽医学等学科方向,体现了多学科、跨领域研究特点;乳酸菌、纤维素酶等添加剂的研究应用最受关注。添加剂种类及添加方式(单一或混合)对发酵品质和有氧稳定性等方面的影响是青贮添加剂领域现阶段的研究热点。

Abstract:

Ensiling fermentation is an important strategy of trans-seasonal preservation of crop straw and forage grass,which is also one of the traditional production methods of animal feed. The addition of silage additives during ensiling process plays an important role for the improvement of ensiling quality,aerobic stability,and utility value. In order to understand the study status and hotspot on silage additives,the literature on silage additives published during the period 2005-2020 were analyzed via the bibliometrics and comprehensive visual analysis based on the core collection of Web of Science and CNKI databases,aiming to provide helps for researchers in defining research direction,conducting scientific research and understanding the field hotspot. The results showed that there were 70 countries or regions,965 research institutions involved the research on silage additives,and the results were published in 187 journals,and cross-regional cooperation was frequent. the total number of publications increased substantially in recent years,suggesting that more and more researchers have begun to pay attention to the investigation on silage additives. The United States,Brazil,Canada and China were identified as the most productive country of researches and presented strong interactional cooperative relationship. Moreover,the literatures from the United States and Canada scholars were more cited frequently in comparation to other countries. The animal husbandry,agriculture and veterinary science are the main research discipline with the feature of multidisciplinary and interdisciplinary. For the past few years,the most attention of silage additives have been paid to lactic acid bacteria and cellulase,and the addition effects of additives on ensiling quality and aerobic stability have become a research hotspot in the field of silage additives,whether or not the single or mixed additives.

Key words: ensiling fermentation, silage additives, bibliometric, development trend
