摘要：

为介绍国内作物连作障碍的研究进展,基于1989—2018年中国知网数据库(CNKI)中连作障碍相关发文情况,通过文献计量学方法分析文献的年代、期刊、机构、基金、作者、研究对象和主题分布等基础信息,并采用CiteSpace V软件对关键词进行科学知识图谱研究。结果表明,连作障碍文献数量总体上与年度变化呈明显正相关关系;受各类资金资助的文献数为2678篇,占总文献量的42.28%,其中受国家自然科学基金资助的文献发表最多;该研究领域文章的刊载主要涉及农业类杂志,研究机构主要涉及农林类高等院校及科研院所;文献作者毛志泉、许艳丽、韩晓增等在该领域研究成果较多;研究对象主要集中在粮食作物、蔬菜作物、水果（树）、经济作物和药用植物5类;该领域研究热点主要围绕土壤微生物、土壤酶、土传病害、化感自毒作用等方面展开,初步形成了以韩丽梅、许艳丽为中心的研究群体。作物连作障碍研究逐渐受到重视,越来越多学者致力于此方向研究,使该领域科研水平和学术影响力得到了较大提升。但作物连作障碍研究中仍有许多领域具有较大空间,基于土壤微生态环境变化视角,探索连作障碍的防治机制,或许将成为未来研究的主要方向。

Abstract:

The paper aims to understand the research progress of continuous cropping obstacles in recent years in China. Based on the publication of relevant articles in CNKI from 1989 to 2018, this paper analyzed the age, journals, institutes, funds, authors, objects and topics of these articles by bibliometrics, and used CiteSpace V software to establish a knowledge mapping of keywords. The results showed that: the number of articles was positively correlated with the annual variation; a total of 2678 articles were funded by various funds, accounting for 42.28% of the total amount of articles, among them, the National Natural Science Foundation of China supported the largest number; these articles were mainly published in agricultural journals, and the research institutes were mainly agricultural and forestry universities and research institutes; Mao Z Q, Xu Y L and Han X Z were the main authors who made more achievements in this field; the main research objects were grain crops, vegetable crops, fruits (trees), cash crops and medicinal plants; the research hotspots mainly focused on the soil microorganism, soil enzyme, soil-borne diseases, allelopathic autotoxicity, autotoxic effect and other aspects, and a scientific research team was formed with Han L M, and Zhang C Y as the core. Nowadays, more and more scholars begin to devote themselves to the study of continuous cropping obstacles in China, and the level of scientific research and academic influence in this field have been greatly improved compared with before. However, there is still much room for development in many fields of crop continuous cropping obstacles research in China. Based on the perspective of soil micro-ecological environment change, exploring the mechanism of prevention and control of continuous cropping obstacles is the main direction of future research.
