With the gradual improvement of people’s living standards, the demand for agricultural products is increasing and the demand for product quality is also getting higher and higher. The extensive application of plastic film in agricultural production has not only enriched the "vegetable blue At the same time, it has also become an important way for peasants to get out of poverty and get rich. Plastic shed in the vegetable production sub-small bow shed, plastic greenhouses and greenhouse three forms. Solar greenhouse greenhouse light lighting insulation is good, strong wind resistance and low temperature, easy to cultivation and management, and more overwintering cultivation of hi-temperature fruit and vegetables to ensure a balanced market of vegetables, high yield and large income. Plastic greenhouse investment is lower, a mu need 5000 ~ 6000 yuan, its main disadvantage is subject to greater external temperature constraints, encountered persistent low temperature, prone to frost damage. Affect the growth and development of crops, generally suitable for fruits and vegetables in early autumn and spring planted in advance
