Atmosphere is the home base of the fruit and vegetable preservation of more advanced facilities. It not only kept in the register regulating temperature, humidity, can control the stored oxygen, carbon dioxide and other gases, so that fruit and vegetable in a hangar dormant, after the Treasury to maintain the original quality.
     1. To extend the storage life of fruits and vegetables are generally longer than ordinary cold store 0.5 times-l times the storage to the most expensive price listed for sale, will be granted the maximum profit.
     2. Can maintain the freshness of fruits and vegetables brittle. Fruits and vegetables after the Treasury, the water content of vitamin C, sugar, acidity, hardness, color, weight, storage requirements can be achieved. Fruit crisp, green vegetables, and the new pick is almost the same shape can be made to provide high-quality fruit and vegetable market.
     3. Fruits and vegetables can inhibit the occurrence of pests and diseases, so that the weight loss of fruits and vegetables and plant diseases and insect pests to minimize losses.
     4. Fruits and vegetables before the library frame period can be extended to 21 days -28 days, and the common cold storage of fruits and vegetables after the Treasury Long before planes can only be maintained for about seven days will turn bad. The so-called modified atmosphere through the gas-conditioning method is to achieve the effect of freshness. Gas regulation is the concentration of oxygen in the air from 21% to 3%. 5%, that is, preservation of library is the basis of high-temperature cold storage, coupled with a controlled atmosphere system to control the use of temperature and oxygen content of the combined effect of two aspects in order to achieve inhibition of respiratory state of post-harvest fruits and vegetables.
    
     Modified Atmosphere library has the following characteristics:
     (1) applies to a wide range: suitable for a variety of South and North China's fruits, vegetables, flowers, nursery stock, such as storage.
     (2) a long period of storage, high economic efficiency. Such as grapes fresh 7 months, 6 months, Apple,蒜苔seven months later, the quality of fresh unabated, with a total loss of less than 5%. The general price of grape production is only 1.5 yuan / kg, while the price of storage before and after the Spring Festival, up to 6 yuan / kg. Built into a one-time cold storage life of up to 30 years, significant economic benefits. Time investment, then effective.
     (3) The technique is simple, easy maintenance. Microcomputer control the temperature refrigeration equipment, automatic startup, shutdown, without special care, supporting technical and economic utility.
