我国蔬菜育苗研究发展态势及其影响因素分析

Developmental Trend and Influencing Factors of Vegetable Seedling Cultivation Researches in China

通过检索中国知网(CNKI数据库)中有关蔬菜育苗的文献,采用文献计量学的方法并借助CiteSpace信息可视化软件,从载文量、文献来源、作者和机构分布及引文情况等多角度,分析了我国蔬菜育苗研究发展态势及其影响因素。结果表明:1992年以来,我国蔬菜育苗研究论文数量呈二次多项式显著增加趋势,根据其自然增长特征,可划分为3个时段,2010年以后进入快速增长期;从文献机构和作者分布来看,南京农业大学和中国农业科学院蔬菜花卉研究所是主要的研究机构,尚庆茂是蔬菜育苗研究文献主要贡献者;1992~2003年,"穴盘育苗"是最主要的研究热点,随后的研究过渡到幼苗生产性能,近年来"机械化育苗"成为热点词,病虫害关注度增加,育苗对蔬菜产业的发展也得到重视;我国蔬菜育苗产业的迅速发展,其重要推动力量来自蔬菜种植面积、出口量的增加等,科技期刊的种类增多、质量提高,科研项目资助强度增大与国家相关政策导向息息相关。随着我国人口数量的持续增长,城乡居民生活水平的不断提高和农村人口向城镇转移加快,商品菜需求量将呈现快速增长趋势,我国蔬菜育苗也将从偏重与产业相关的技术研发,转向基础理论、关键技术的多学科交叉发展。

Through searching the literatures related to vegetable seedling cultivation in China National Knowledge Infrastructure(CNKI)database,by adopting bibliometrics method and CiteSpace information visualization software,the author analyzed the developmental trend and influencing factors of vegetable seedling cultivation researches in China from the aspects of published literature quantity,literature source,author and institute distribution,and citation situation.Since the year 1992,the quantity of published research papers related to the cultivation of vegetable seedlings in China showed a significant and quadratic-polynomial increasing trend.According to the natural growth characteristics of vegetable seedling publications,three developmental periods could be divided since 1992,and the rapid growth period was after 2010.In terms of the distribution of literature authors and institutes,the main research institutes were Nanjing Agricultural University and Institute of Vegetables and Flowers,Chinese Academy of Agricultural Sciences;Shang qing-mao had the most contribution to the research papers on vegetable seedling cultivation.Before 2003,“plug seedling”was the main research hotspot in the field of vegetable seedling cultivation in China;since 2003,the production performance of vegetable seedlings was gradually noticed;in recent years,mechanized vegetable seedling cultivation became a hotspot,more attentions were paid to the prevention and control of vegetable diseases and pest insects,and the development of vegetable seedling industry was also concerned.The fast development of vegetable seedling industry in China was mainly dependent on the increase in planting area and export quantity of vegetable,the advancement of kind and quality of technical journals,the obvious increase in the funding for vegetable scientific researches,and the guidance of national relevant policies.Along with the continuous increase in population size,the continuous improvement of living standard of urban and rural residents,and the accelerated transfer of rural population to cities and towns,the demand for commodity vegetable in China will increase rapidly,and the research directions of vegetable seedling cultivation will transfer from industry-related technologies to basic theory and key technologies.
