The choice and application of vegetable transportation methods

The transportation of vegetables is highly dependent on the characteristics of each vegetable variety. The choice of transport method typically balances the need to protect the goods, ensure efficiency, and keep costs low. However, it is also influenced by seasonal changes and environmental conditions. Today, a wide range of transportation methods—such as railways, highways, waterways, and air transport—are commonly used. These modes complement each other, forming a well-established network that greatly supports the nationwide distribution of fresh produce. (1) Transportation Modes 1. Railway transport offers high capacity and low cost, but it is affected by seasonal variations. Although it involves multiple transfer points and lacks flexibility, it remains a primary mode for transporting bulk vegetables over medium to long distances. 2. Highway transport provides greater flexibility and direct access to markets, allowing for “door-to-door” delivery without changing packaging. It is ideal for reaching remote areas or industrial zones not served by rail. However, it can be costly and has limited capacity. Road conditions also affect product quality due to vibration and potential damage. 3. Water transport, including both inland and ocean routes, is cost-effective and stable with large carrying capacity. However, its slow speed and poor continuity make it unsuitable for time-sensitive goods. It is best suited for long-distance transport of non-perishable vegetables or processed products. 4. Air transport is fast and minimizes damage, making it ideal for high-value, delicate vegetables like lettuce, mushrooms, and certain leafy greens. However, its high cost limits its use to special cases or premium products. 5. Container transport enhances efficiency through seamless intermodal operations, reducing handling time and improving logistics coordination. This mode is gaining popularity and holds significant growth potential. (2) Transportation Equipment Selecting appropriate transport tools based on local conditions is essential for achieving economic and efficient vegetable distribution. In coastal or riverine areas, boats, barges, and small ships are often used for short-distance transport. For longer trips, larger vessels equipped with temperature control systems are necessary to maintain freshness. Road transport is widely used in China. Short-distance vehicles may include tractors or animal-drawn carts, while long-distance transport relies on trucks, refrigerated trucks, and specialized vehicles. Proper packaging, cooling, and temperature management are crucial to preserving quality. Refrigerated trucks are the best option, as they allow pre-cooling and maintain stable internal conditions during transit. Rail transport has a long history and includes various types of vehicles. General box cars offer basic protection but lack climate control, making them suitable only for less sensitive vegetables. Ice refrigerated trucks use ice or salt mixtures to cool cargo, though temperature control is limited. Mechanical refrigerated trucks, equipped with advanced cooling systems, provide better temperature regulation and are more suitable for long-distance transport. Insulation and ventilation cars offer a cost-effective solution with good thermal protection and controlled airflow. They are ideal for medium-distance transport and have been successfully adopted in many developed countries. Refrigerated containers, which combine insulation with active temperature control, are becoming increasingly popular due to their versatility and efficiency. In summary, the selection of transportation methods and equipment depends on the type of vegetable, distance, and environmental factors. A combination of different transport modes ensures that vegetables reach consumers in optimal condition, supporting the growth of the agricultural supply chain.
