Chinese greenhouse vegetables crop production survey

       The greenhouse may create a miniature climate for the crops, also can protect the crops not the climatic conditions influence.The greenhouse planter receives extremely in China welcome, although it compared to open-air planter need more capitals.The greenhouse planter also allows the grower to be possible while to produce the high quality vegetables obviously to enhance the output.The greenhouse brings other superiority including more effective use resources and sowing seeds flexibility.
       China's greenhouse has two kind of types: Bamboo structure and steel and iron structure.
       The bamboo structure greenhouse may construct 1.5 meters highly to 1.8 meters, the area is smaller than 0.1 hectare.The construction bamboo structure greenhouse, each hectare needs to spend 2000 Yuan to 8000 Yuan.The bamboo structure greenhouse usually by the transparent plastic thin film cover, preserves the sunlight and the temperature.North they usually use in when the spring autumn temperature change is big, because constructs simple, the service life is also short.
       The steel and iron structure greenhouse is higher, compares the bamboo structure greenhouse to be possible to cover a broader land.They the scope in 1.8 meters to 4 meters, may cover 0.1 highly to 0.3 hectares land.Constructs the steel and iron structure greenhouse the cost to compare the bamboo structure greenhouse to have the distinct enhancement, each hectare needs to spend 20000 Yuan to 100000 Yuan.The steel and iron structure greenhouse is longer than the bamboo structure greenhouse service life, holds the more complex climate system.Compares the individual peasant household, the large-scale agricultural enterprise can undertake constructs the steel and iron structure greenhouse the cost.
       China's greenhouse vegetables planter output had the remarkable growth in past several years, increased 2009 from 2005 154,600,000 tons 186,000,000 tons, the year compound rate of increment is 4.7%, estimated will amount to 276,000,000 tons in 2014.In vegetables ultimate output occupying compared to by 2005 27.4% growths to 2009 30.9%, anticipated grows in 2014 to 39.4%.
Greenhouse crop production competition pattern
       The greenhouse vegetables crop production highly decentralizes as before in China, also because the profession participant is multitudinous, including the individual agricultural household, the state-owned agricultural enterprise and operates privately the agricultural company, the competition quite is intense.In 2009, the individual agricultural household approximately constructed the greenhouse on 3,600,000 hectares lands, the vegetables planter company has constructed the greenhouse on 350,000 hectares lands.The individual agricultural household constructs the greenhouse area is greatly because government for improves the rural population welfare to encourage them to construct the greenhouse, and gives the fiscal subsidy.The greenhouse vegetables planter enterprise output enhances is obviously because they have the advanced technical equipment, the management idea and the economies of scale effect.
