The completion of the cold chain logistics of agricultural products requires a series of operation processes, and there is a distinct industrial chain of cold chain logistics enterprises. In recent years, relevant departments have released a series of working documents on cold chain logistics, focusing on system integration of logistics resources, cold chain logistics facility layout, and cold chain logistics system inventory construction, etc. The development of chain logistics.

At this stage, the development of cold chain logistics is a new trend of agricultural modernization in my country, and it is a technical means of comprehensive solutions to maximize the benefits of agriculture. From the production area to the sales area, from the farmland to the dining table, the construction of a cold chain logistics system is an important and necessary action. It can ensure the food hygiene and safety of the people, improve the overall level of cold chain logistics, promote the rapid and efficient development of agriculture, and improve the urban and rural areas. quality of life of residents. Taking M city as an example, this paper analyzes the current development of cold chain logistics and puts forward relevant suggestions.

1. Problems existing in the development of urban agricultural product cold chain logistics

M City is known as the "natural greenhouse" and is the main producing area for lychee, longan and banana production; the output of aquatic products is in the forefront, and it is a modern agricultural base with provincial characteristics. With the continuous development of my country's economy, people's lives have gradually improved, and the per capita consumption level has been greatly improved. The scale of cold chain logistics in M City has also expanded, and its industrial status has been greatly improved. At the same time, the consumption level of cold chain food by residents in M City is also increasing year by year. Coupled with the emergence of online shopping, cold chain transportation requires us to pay more attention to the process, which makes cold chain logistics transportation more important in the daily life of residents. Always at a higher level. The rapid development of the leading enterprises of agricultural products in M City has laid a solid foundation for the steady growth of brand building, pre-cooling of origin and processing. At present, most food and cold chain logistics and transportation companies have basically equipped several refrigerated transportation vehicles, and have built small cold storage and other facilities in various places, which can ensure the cold storage of fruits and vegetables, meat, milk, eggs, aquatic products and other aspects that residents need in their daily lives. Chain transport supply. However, from the current point of view, the development of cold chain logistics and transportation in M City is still in its infancy, and there are still some obvious problems in the development process of cold chain logistics and transportation, mainly reflected in:

One is the contradiction between supply and demand of cold chain facilities. On the one hand, the supply and demand of cold chain logistics is not balanced. The per capita cold storage occupancy and construction standards are relatively low, the relevant management and operation are extensive, and the construction standards are not uniform, which makes it difficult to effectively ensure food safety. On the other hand, the layout of cold storage is unreasonable, and the cold chain facilities and refrigeration technology in M City are relatively lacking. In addition, many crops have different characteristics in different seasons, and there are significant problems such as large seasonal price fluctuations and short storage time." ;Low fruit hurts farmers" also happens from time to time.

Second, the circulation rate of the cold chain is low, and the phenomenon of "broken chain" occurs in large numbers in the process of economic development of enterprises. Local fresh produce is mostly circulated at room temperature. However, the weather there is relatively hot, and the quality of fresh products cannot be fully guaranteed, or the whole process of cold chain transportation cannot be realized, which makes the products more prone to deterioration and affects the utilization rate of fresh products. To explore the reasons for this phenomenon, first of all, the workmanship is not in place in the packaging stage, the temperature control work still needs to be strictly controlled, the operation of the distribution link is not standardized enough, and the systematic cooperation and operation between the various links of cold chain logistics is extremely important. interact, relate to each other. A standardized, integrated and systematic cold chain logistics system has not yet been formed, and the entire temperature control system and quality traceability system have not been widely popularized during the transportation process.

Third, the integration and professionalism of cold chain logistics enterprises is relatively low. The construction scale of cold chain logistics and transportation enterprises in M city is relatively small, and the current service level and quality also need to be further improved. There are problems in technical equipment, which need to be improved and continuously innovated. With the stagnation of economic development of third-party cold chain logistics and transportation management enterprises in my country, the bottleneck problem of urban cold chain distribution has not been fundamentally solved. At present, the express companies in the market for cold chain transportation are only a few companies such as SF Express, JD.com, Debon and Post.

Fourth, the supporting service system is not complete enough. Cold chain logistics transportation is extremely important to ensure the quality of fresh agricultural products, but there are many problems at present. The cold chain logistics information sharing ability is insufficient, the logistics information cannot be effectively provided, and the shared information cannot be transmitted, which leads to a great discount on the entire transportation. In addition, there is a shortage of professional and technical personnel in the cold chain at this stage, and the cold chain logistics transportation has not yet reached the standardization construction. The technical draft is imperfect, and the implementation lacks effective monitoring.

Fifth, the construction and operation cost of cold chain logistics is relatively high. Due to the cumbersome procedures for my country's current cold chain land use and the control of national land planning, many lands suitable for the centralized development of cold chain logistics projects are included in the scope of basic farmland, and no other related construction projects are allowed to develop. In addition, cold chain cold storage belongs to commercial power consumption, and a large amount of power consumption has brought expensive economic consumption to enterprises.

2 Suggestions for development

In the future development, we should aim to accelerate the development of cold chain logistics construction of agricultural products, and design a network system for cold chain infrastructure construction that is rationalized, comprehensively covered, and effectively connected to all locations. The application of new technology to the whole process of cold chain logistics can effectively improve the development of cold chain transportation of logistics agricultural products. The following suggestions are put forward.

1. Establish a convenient information sharing platform to facilitate understanding of logistics information. With the rise of 5G, the logistics platform built by the combination of network and logistics will be more convenient. It can provide diversified services for local agricultural product logistics services, and is equipped with positioning tracking and temperature control systems in accordance with the standard. Ensure that the cold chain transportation process can be reasonably supervised. Promote the effective construction of the city's cold chain logistics transportation public information inquiry service and quality and safety supervision and traceability platform, and promote the information sharing links between enterprises and enterprises, government and enterprises, and people and enterprises.

2. Comprehensive coverage of the cold chain facility network. Effectively strengthen the construction of cold chain logistics transportation, gradually build and improve the network covered by cold chain logistics while building, encourage and advocate the use of refrigerated containers, so that cold chain transportation can also play a role in the process, important cold chain logistics. The chain logistics transportation nodes are updated and improved, the park is built, the development of the cold chain logistics industry is promoted, and the order mode is used to better cover the full coverage of cold chain logistics. At the same time, cooperatives, service points, agency stations, etc. are used to provide cold chain services for more places.

3. Improve the technical level of cold chain logistics. The construction of cold chain must be based on strict temperature control. Because cold chain logistics has high requirements, it is necessary to use advanced technology to improve its operation level and promote the effective and safe delivery of logistics. Therefore, the first is to study technologies and equipment that can control the decay time of agricultural products in a short time, so that the products can have a longer period of time to ensure the safety of their consumption; the second is to strengthen the supervision of cold chain enterprises and strictly follow low energy consumption standards. Green and environmentally friendly cold chain projects; the third is to use low-loss environmentally friendly cold chain vehicles to ensure ecological quality, improve service levels, promote the promotion of characteristic agricultural products, and make cold chain logistics related facilities more standardized and professional.

4. Promote pre-cooling technology from the source. Encourage the appropriate development of technologies related to the processing cold chain in the production area, and solve the main problem of "the first kilometer" from the source through the development of primary processing cold chain facilities. To fundamentally control the problem, reduce the deterioration of agricultural products in the process of cold chain transportation, ensure the initial quality of the product, and make it free to adjust and increase or decrease according to changes in market demand. Strengthen the construction of aquatic product bases. In the core aquatic product production areas, speed up the construction of fast-freezing warehouses, cold storages, processing workshops and other facilities, improve the hierarchical packaging, processing, low-temperature storage, and transportation systems of aquatic product bases, and improve the entire logistics system of aquatic products from origin to dining table. At the same time, it can also develop a similar tourism industry, make the aquatic product production area a tourist attraction, and effectively realize the two-way benefit of the operators. Influence the awareness of more farmers and operators through giant enterprises, continue to expand the cold chain industry, and at the same time let farmers feel that "landmarks" can help everyone get rid of poverty and become rich, and achieve a better life.

6. The administration and the market cooperate with each other to achieve win-win cooperation. Government departments should vigorously support the publicity of geographical indication products, realize the resonance of "administrative power" and "market power", and create product brands with quality, characteristics and unique style.

In the future, the cold chain logistics service chain will continue to grow, and at the same time, more logistics talents will emerge, pioneering and innovating more advanced technologies, driving the development of my country's cold chain transportation, and making my country's logistics industry gradually gain a firm foothold. It has become a model for reference by other countries in the international arena.
