Since the reform and opening up, the mechanization level of China's agricultural production has been significantly improved. Intelligent mechanization of agricultural production is an inevitable trend for future social development. It is based on intelligent equipment, with data and knowledge as the core elements to enable the deep integration of modern science and technology with agriculture. This enables digital perception, intelligent decision making, and precise operation of the whole agricultural production process, further improving labor productivity, land output rate and resource utilization rate. This paper introduces the development status of agricultural production in China and abroad with pepper harvesting, analyzes the necessity of changing China's agricultural production to intelligent mechanized production, summarizes the opportunities and challenges in intelligent mechanization, and accordingly puts forward the development direction and development route of China's agricultural production. To promote the transformation of China's agricultural production mode from mechanization to wisdom, this paper puts forward countermeasure suggestions such as strengthening the construction of agricultural machinery equipment R&D and innovation system, strengthening the construction of agricultural machinery promotion system, strengthening the construction of agricultural machinery socialization service system, and accelerating the construction of wisdom agriculture demonstration area.
