Research progress of forest tree seed orchards based on CiteSpace
To understand the research status and hot spots of forest tree seed orchards,the literature of forest tree seed orchards from 1962 to 2023 in CNKI database was retrieved,and quantitative analysis was carried out in terms of the annual publication volume,publication journals,fund programs,research institutions,key words,outburst words,and cited references frequency by using bibliometrics.The study showed that the attention to seed orchards has been increasing,and the annual number of published papers was on the rise,but the innovation and depth of the paper need to be strengthened in recent years.Journals with high volume of core libraries included Journal of Nanjing Forestry University(Natural Science Edition),Research in Forestry Science,and Journal of Northeast Forestry University,etc.The fund projects mainly came from national research funds and provincial projects.Authors such as Zhang Hanguo,Zhang Zhen and Jin Guoqing had published many papers in the field of forest tree seed orchards research.The research institutions included the Institute of Subtropical Forestry,Chinese Academy of Forestry,Northeast Forestry University and Huazhong Agricultural University.Combined with key words and emergent words,the results showed that Chinese fir,masson's pine,and Chinese pine were the main tree species in the forest tree seed orchards,and the research contents focused on the genetic variation of growth traits and progeny measurement in the family and clonal lines.The literatures with high citation frequency mainly studied the genetic breeding and variation of forest tree seed orchards.In the future,we will further focus on genetic inheritance,genetic engineering,and other fields to carry out diversified breeding research,so as to provide references for forest tree seed orchards construction.
