Abstract:

CNKI network database is chosen to analyze the research situation of degradable mulching film in China during 1987-2018 by bibliometrics. The results showed that the number of literatures on degradable mulching film was relatively small, but increased in the past 10 years; all regions in China were covered by the researches, Xinjiang, Gansu and Shandong were the top three regions. The research information sources were widely distributed, but there were few high-quality journals; the researchers were scattered and the core authors were not prominent; scientific research institutes and universities were the main research units, and most of the studies focused on the effect of degradable mulching film on soil hydrothermal and crop yield, but the research on degradation mechanism and environmental safety were relatively lacking. It is suggested that the research direction of degradable mulching film in the future should meet the requirements of functionality, operability, controllability, economical efficiency, safety and compatibility.

Key words: degradable mulching film, bibliometrics, CNKI, analyses
