Research Situation Analysis of Straw Returning in China Based on CNKI
In order to accurately and objectively analyze the development trend of straw returning field in China,and provide a reference for the efficient utilization of straw resources,CNKI full-text database was used to analyze the publication time,number of papers,research institutions,citation and other indicators of relevant papers in this field.Combined with the CiteSpace keyword visual analysis method,the research overview of straw returning field in China was systematically described,and the hot spots and development trends of straw returning research in China were analyzed.The results showed that the research on straw returning to the field in China was in the stage of rapid development,and the number of papers published increased exponentially;The top three research institutions in the volume of papers were China Agricultural University,Northwest Agriculture and Forestry Uni-versity and Nanjing Agricultural University.Lu Jianwei from central China Agricultural University,Zhang Renzhi from Gansu Agricultural University and Chen Fu from China Agricultural University were active researchers in this field;Relevant articles published were distributed in journals such as Transactions of the Chinese Society of Agricultural Engineering,Journal of Plant Nutrition and Fertilizer Science,and Chinese Journal of Soil Science;The hotspot of straw returning research in China mainly focused on the regulation of farming and agronomic measures and the effect of straw returning measures,mainly including increasing yield,improving soil fertility and related biological mechanisms.In general,the research focus of straw returning in China has changed from the yield and soil fertility to the biological mechanism of straw returning.Soil greenhouse gas emissions,soil micro-organisms and soil enzyme reactions were the main trends of straw returning research in China in the future.
