摘　　要：综合中国知网、维普、万方数据库收录的2000—2021年发表的涉及农作物根系分泌物的中文试验性文章,搜索关键信息进行分析。结果显示:42%的研究涉及的农作物集中在小麦、大豆、玉米、水稻、蚕豆等粮食作物上。作物、微生物、土壤是探索外在环境与根系分泌物互作中所涉及的主要因素。互作研究主要包括农作物根系分泌物对外在环境的影响和根系分泌物对外在环境的响应。对农作物根系分泌物成分的分析在精度上主要可分为全量检测(占总研究的39%)、功能成分分析(占总研究的50%)和全成分分析(占总研究的11%)3个层次。尽管脂类、烷烃类、醇类等大分子量化合物在农作物根系分泌物中的种类占所有化合物种类的比例较高(41%),但对酸类、氨基酸类、糖类等低分子量且种类较少的初级代谢产物的研究数量占比较高(24%)。总的来看,粮食作物是我国农作物根系分泌物研究的重点,且根系分泌物的全成分分析尚处于发展初期。农作物根系分泌物中酸类、氨基酸和糖类等初级代谢物的功能与外在环境的互作是当前的研究热点。Based on the experimental studies on crop root exudates published in Chinese from 2000 to 2021 in the databases of CNKI,CQVIP and Wanfang,the hotspot of crop root exudates studies was preliminarily explored.It was shown that 42%of the published studies focused on wheat,soybeans,maize,rice,faba beans.Crops,microorganisms and soil were the main factors involved in the interaction between external environment and root exudates.Interaction studies mainly focused on the influence of crop root exudates on the environment,and the response of root exudates to the environment.Based on the analysis accuracy of crop root exudates,relative studies could be divided into three levels,namely,total detection(39%of the total studies),functional component analysis(50%of the total studies)and total component analysis(11%of the total studies).Although the types of large molecular weight compounds such as lipids,alkanes and alcohols in crop root exudates accounted for a relatively higher proportion of all compounds(41%),the number of studies on low molecular weight and a few types of primary metabolites such as acids,amino acids and sugars accounted for a relatively higher proportion(24%).In general,grain crops are the focus of root exudates research in China s agricultural system.The full analysis of root exudates is still in the early development stage.The interaction between the functions of acids,amino acids and primary metabolites of sugars in crop root exudates and the external environment is the hot topic at present.
