Climate change with warming as the main characteristic has important influence on crop phenology. Rising temperature usually leads to faster crop growth and shortened growth period that causes loss of crop yield, which is not conducive to agricultural development. Meanwhile, crop phenological changes can reflect climate change directly or indirectly, which has important significance for detecting climate change. Research on crop phenology is crucial for preventing agricultural meteorological disasters, the progress of agricultural production management, and the safety of agricultural production. With the continuous increase of global surface temperature, research on crop phenology has attracted increasingly more attention of scientists. Based on the key research methods of crop phenology, this article summarizes the studies on the change of crop growth period and the main driving factors of change of major crops, including wheat, corn, rice, cotton, and soybean, in recent decades in China. The following conclusions are drawn: 1) Statistical analysis methods have been most widely used and several other methods were combined with statistical analysis methods in application. Model simulation method has also been widely used in phenological research, and such method is easy to operate. Remote sensing inversion has a high requirement on the characteristics of the growth period, and the focus is generally on green-up period of spring crops. 2) Overall, the whole growth period of wheat is mainly shortened, and the main trend of whole growth period of maize and rice is prolonged. 3) The driving factors of main crop phenological change is climate change and agricultural management. Climate change is the dominant driving factor, which decides crop phenological change, and adjusting agricultural management measures can partly offset the negative impact of climate change on crop growth period. The study of response and adaptation of crop phenology to climate change can provide an important theoretical basis for agricultural production to adapt to climate change.
