Although the six-day study time is short, it has further deepened my knowledge and understanding of agricultural technology popularization. Agricultural extension is to impart new knowledge, new technology, new achievements, new information and new ideas to farmers through experiments, demonstrations, exchanges and guidance, so that farmers can consciously change their concepts and behaviors, thus changing their self-decision-making and management capabilities, promoting the all-round development of rural economy and society, and improving the level of rural material civilization and spiritual civilization. Through this study, I further understand and know the process and present situation of agricultural development in China and the meaning of modern agriculture. The characteristics and types of modern agriculture in China have deepened the understanding of the theory and practice of modern agricultural extension in China, and not only learned new theoretical methods and some skills needed in practical work, but also learned some cutting-edge technologies and knowledge of current agricultural scientific research. It has promoted the transformation of my thinking mode and working method, and improved my professional quality and comprehensive skill level.
