Modern irrigation methods, such as drip irrigation, not only save water but also deliver water directly to the root zone of the plants, promoting better growth and higher yields of purple sweet potatoes.
• Storage Facilities: Adequate storage facilities have been built to preserve purple sweet potatoes after harvest. These storage facilities are equipped with proper temperature and humidity control systems. By maintaining the appropriate storage conditions, the spoilage of purple sweet potatoes can be minimized, and their quality can be maintained for a longer period. This is essential for ensuring a stable supply of raw materials for the extraction of purple - sweet - potato extract components throughout the year.
• Transportation Networks: Well - developed transportation networks in China enable the efficient movement of purple sweet potatoes from the fields to processing plants. Good roads, railways, and logistics systems ensure that purple sweet potatoes can be quickly transported without significant damage or spoilage. This timely transportation is crucial for maintaining the freshness and quality of purple sweet potatoes, which in turn affects the quality of the extract components.

4. Government Support for Agricultural and Food - Processing Industries

4.1 Policy Incentives for Technological Innovation

The Chinese government has implemented various policies to encourage technological innovation in the agricultural and food - processing sectors related to purple sweet potatoes. For example, there are subsidies and tax incentives for research and development activities in purple sweet potato breeding, cultivation techniques, and extraction methods. These incentives have attracted many agricultural research institutions and enterprises to invest in the development of new purple sweet potato varieties with higher yields and better quality. In addition, research on more efficient and environmentally friendly extraction technologies has also been promoted, which has improved the quality and purity of purple - sweet - potato extract components.

4.2 Support for the Development of High - Value - Added Products

The government also provides support for the development of high - value - added products based on purple - sweet - potato extract components. This includes support for product certification, marketing promotion, and international cooperation.
