Study On Sunlight Greenhouse Vegetable Industry Of Guanzhong Region

Analyse the main problems that influence the production of vegetables in sunlight greenhouse in Guanzhong from two prospects, production technology and industrial point of view. Have investigated actually the situation of vegetable production in 5 counties(area) of Dali, Chang'an, Qingdu, Weicheng, Meixian and so on in Guanzhong,Shanxi province. And also search some papers about advanced production technology and experience of vegetables in sunlight greenhouse. Technical constraints include the irrational greenhouse structure which influence lighting performance, thermal insulation property and security property. Imperfect cultivation techniques lead to low quality and quantity. Soil impediment including increase in pests,soil degradation, gets worse yearly which affect vegetable production. Constraints of Industrial development include low level of industrialization, imperfect industrial division, which influence enhancement the efficiency of farmers. Supporting measures are not perfect, such as lack of development funds, difficulty of land concentration for large-scale development. We propose to optimize greenhouse structure, enhance property of secure production, implement standardized management, produce high quality vegetables, employ suitable small machinery actively and improve efficiency of production. Government of agricultural management should help farmers to improve the degree of organization, support the growth of leading enterprises and strengthen policy support in agricultural insurance, land transfer, technical training for farmers to promote rapid, healthy and sustainable development of vegetable industry in sunlight greenhouse.
