In recent years, the agricultural machinery department has focused on the difficulty of maintaining the freshness of agricultural products in the development of agricultural product planting in some township farmers in our city, focusing on the production areas of characteristic agricultural products such as bamboo shoots, pecans, tea, and fruits, using the guidance of the purchase subsidy policy. , Build fresh-keeping cold storage for them, and promote the application of cold storage technology for agricultural products. 'The shiitake mushrooms that have been planted for so many years are the best-selling this year. The wholesale price of a pound of shiitake mushrooms has been sold for 3 yuan and 80 cents.' Lao Li, a farmer in Fangtang Township who has grown shiitake mushrooms for 4 to 5 years, told reporters. In the past, due to the lack of good fresh-keeping measures, farmers could only reluctantly make dried shiitake mushrooms from the fresh shiitake mushrooms in their hands, and the price could not go up. 'Speaking of this cold storage, it has helped us a lot. Put shiitake mushrooms in it, and there is no need to worry about deterioration for a few months. Now, many farmers sell fresh shiitake mushrooms, and the price is more than 30% higher than that of dried shiitake mushrooms.' It is understood that since 2008, Fangtang Township and the municipal agricultural machinery department have jointly built 18 such fresh-keeping combined cold storages for farmers. At present, there are more than 160 various cold storage storages in various towns and streets in our city. By extending the preservation period of agricultural products, the added value of agricultural products has been increased, and the economic benefits generated by them have increased by 15-40%. In 2009, our city increased the income of farmers by nearly 10 million yuan through the cold chain logistics of agricultural products after refrigeration and preservation.
