Study Of The Transformation And Performance Of Greenhouse Using Glass Fiber Reinforced Plastics

The greenhouse is the main facility of the protectorate cultivation, it manifests the national level of the facility agriculture development. In recent years, Many works guarantee the healthy development of the greenhouse profession, such as a lot of results were yield on frame construction of the greenhouse, control facility of the temperature and humidity, automatic facility, Cladding material etc. at the same time, some codeslstandards of the greenhouse facility have been put into effect. Sunlight greenhouse take the cladding material with the plastic membrane, exist some questions as bad heat preservation ability, short service life, big labor intensity. Fiber glass reinforced plastics (FRP) have high strength, high light-admitting quality, low heat conductivity, easy to form and so on the merits, so we experimentally apply FRP to the sunlight greenhouse as cladding material of the first slope face, and carry on check experiment with transformed sunlight greenhouse and ordinary sunlight greenhouseThe article summarizes the development of domestic and foreign greenhouses, points out the trend of development. Unifies the state-of-the-art of our country's greenhouse and actual situation of our province, article expounds the necessity and the importance of the technological transformation using FRP to the sunlight greenhouse.The article accesses the trial greenhouse that satisfy the requests of climatic condition, transportation, necessary facility, management, promotion and so on. The structure and parameter of trial greenhouse were studied in order to obtain the universal experiment result.Basing on analyzing influence of the temperature and humidity to greenhouse crops, we rebuild the trial greenhouse, specially solve the problem of installment and seal that apply FRP replacing the ordinary plastic film to the sunlight greenhouse as cladding material of the first slope face, and rebuild the upper and lower air-vent of the greenhouse using the characteristic of FRP.We plant synchronous tomato in trial greenhouse and guarantee the same external condition and the planter method in check experiment that the experimental results accurately reflect the difference of the trial greenhouse itself. We study the position of the experimented equipment and determine the recording method of the experiment data.
