Planting benefits and development measures of new agricultural greenhouse circulation model in North China-A case study on conjoined greenhouse pattern of "vegetable/fruit-edible fungus" in Xushui County

Current facility vegetable industry development has been significantly improved in Xushui County of Hebei Province that it has now become the emerging industry with high farmer income. However, problems gradually emerge in the production process with the expansion of vegetable industry. Problems such as vast areas of sunlight greenhouses, equipment of relatively simple infrastructure, backward environmental control, poor production management and low labor productivity have been all too rampant issues in facility vegetable industry. Xingnong Vegetables Professional Cooperatives in Xushui County changed the greenhouse structure and improved the two aspects of planting patterns via cleaner production, exploration of circular agriculture mode of "vegetable/fruit-edible fungus" planting based on conjoined greenhouses of mushroom-house/vegetable greenhouse and opening up new path to facility vegetable industry development. This paper studied economic benefits and development measures of "vegetable/fruit-edible fungus" stereo planting cycle of agriculture. The research objectives were to determine the costs and economic benefits of conjoined greenhouses, executing quantitative comparative analysis of economic efficiencies of conjoined greenhouses and common greenhouses, and putting forward development measures for conjoined greenhouse planting cycle of agriculture. The research method combined the normative analysis and empirical analysis. Firstly, the design structure and cultivation measures of conjoined greenhouses were comprehended through field investigation and interview with farmers, and then the industry chain structure and characteristic patterns of the mode were analyzed. Secondly, the costs and economic benefits of conjoined greenhouses and common greenhouses were compared by track monitoring and questionnaire survey. Based on the three years of research data, the paper concluded that economic benefits of "vegetable/fruit-edible fungus" mode were higher than the other four ordinary greenhouse modes. In comparison with eggplant, green pepper, tomato and towel gourd outputs of the four vegetables, the annual net incomes of conjoined greenhouses were respectively 6.3, 3.5, 2.3 and 1.1 times that of traditional greenhouses. Because conjoined greenhouse mode greatly improved labor productivity, it was worth the wide promotion in North China. Finally, development measures of conjoined greenhouse planting cycle of agriculture were advance. These included establishing diversified investment and financing mechanisms, improving subsidy system in production processes, building vegetable marketing systems and establishing standardization of pollution-free vegetable bases.
