In order to meet the requirements of consumers and ensure high freshness, nutritional quality, safety and health of fruits, vegetables and flowers, the establishment of a fruit, vegetable and flower logistics system is more and more important. However, the logistics of fruits, vegetables and flowers in China has many problems, for example, the logistics industry is relatively laggard and mainly depends on farmer markets and wholesale markets; the transaction mode is relatively lagged, namely the on-site transaction, and in addition, the main body of the transaction is scattered and the like. China is wide in breadth, due to the influence of factors such as climate and terrain, the variety of planted fruits, vegetables and flowers is various, the improvement of science and technology promotes the increase of the yield of fruit, vegetable and flower products year by year, and most of the products flow to the market and become commodities except for self-use of growers. The loss of Chinese fruits, vegetables and flowers in the logistics process is very large, such as melons, fruits and vegetables, the loss in the logistics is 25-30% in general, and is generally 5% in developed countries and even lower in the United states, so that the cost of the Chinese fruits, vegetables and flowers is very high, and the solution is needed urgently.

The logistics of fruits, vegetables and flowers is characterized by multiple varieties, large scale, diversity, dispersity, seasonality, strong regionalism, freshness, activity, timeliness, vulnerability, complexity and systematicness. The freshness activity and timeliness are particularly important, the requirement of people on the freshness of fruits, vegetables and flowers is higher along with the improvement of living standard of people, the fruits, vegetables and flowers are still fresh and alive organisms after being picked, and therefore the respiration and transpiration effects of the fruits, vegetables and flowers are reduced by adopting cold chain transportation, and the freshness of the fruits, vegetables and flowers is kept.

The cold-chain logistics industry of fruits, vegetables and flowers is an important link of postpartum agriculture, in order to ensure the quality of fruits, vegetables and flowers and improve economic benefits, the whole logistics process is required to be carried out at a specific temperature, but most of the current fruit, vegetable and flower products in China directly enter the market after delivery, the products are initial and semi-initial agricultural products sold on the market, and no treatment measures for precooling and refreshing are provided, so that the fruits, vegetables and flowers lose huge value-added opportunities and space. The application range of the fresh-keeping and cold-chain logistics industry is narrow, the development is lagged, the loss rate of fruits, vegetables and flowers in each year is as high as three, the waste phenomenon is very serious, the loss rate of fruits, vegetables and flowers in developed countries is generally controlled to be below 10%, only less than 30% of the total amount of fruits and vegetables in China utilizes low-temperature logistics in the development process, the varieties are only limited to fruits with high economic benefits, and developed countries generally have about 70%.
