In recent years,the phenomenon of remaining green and delaying maturity of soybean has occurred frequently in the Huang-Huai-Hai area,and has been increasing year by year,seriously threatening the safety of soybean production.The main manifestation of this phenomenon is that the pods are not bulging or wrinkled with thick green leaves,and pods,leaves,and stems remaining green for a long time at the late stage of soy-bean growth,leading to an imbalanced growth,an obstruction of nutrient transport,and a reduction in soybean production.In order to explore the causes of remaining green and delaying maturity of soybean,a comprehen-sive analysis was conducted on various biological and abiotic factors,including temperature,pests,viruses,etc.,based on the research results of relevant scholars and the author's team.The damage caused by Riptortus pedestris is a key factor leading to the remaining green and delaying maturity of soybean,and other factors need to be further confirmed.In order to reduce the occurrence of this phenomenon,comprehensive control measures for R.pedestris in soybean field was proposed.
