Sweet potato is a globally important food crop with rich nutritional value, widely used in food processing, feed production, and the pharmaceutical industry. Hainan Province in China has a history of sweet potato cultivation spanning over 300 years and has long been one of the major sweet potato-producing areas in southern China.

As the global population continues to grow, climate change intensifies, and agricultural resources become increasingly scarce, traditional agricultural production models are facing unprecedented challenges. It is predicted that by 2050, global food production will need to increase by 70% to meet demand. Against this backdrop, “Agriculture 4.0” has gradually emerged, with embedded technologies such as the Internet of Things (IoT), artificial intelligence (AI), unmanned aerial vehicles (UAVs), and robotics widely applied in precision agriculture to improve production efficiency and sustainability.

In the field of modern agricultural machinery, pneumatic conveying seed-discharge systems have been widely adopted due to their compact size, high seed-discharge efficiency, and strong adaptability, which are particularly aligned with the current development trend of high-speed mechanized operations.

With global population growth and rising food demand, agriculture ensures food supply while bringing severe environmental problems. Among these, agricultural non-point source pollution (ANPSP) has become one of the major factors affecting water health and ecological security.

In the vast cotton fields of Xinjiang, plastic film covering technology has been a weapon for increasing yield—it conserves water, raises temperatures, and improves water utilization efficiency, significantly boosting cotton production in arid regions.
