北京市日光温室与塑料大棚生产效益分析
Production Efficiency Analysis of Solar Greenhouse and Plastic Big-arch Shelter in Beijing
摘要
Abstract
From April to August 2010, we visited 804 practitioners (791 households and 13 enterprises/cooperatives ) in 13 counties, 63 towns and 124 villages, and investigated the overall situations and economic efficiencies of solar greenhouse and plastic big-arch shelter from 2009-2010. The results showed that the input-output ratio of edible fungus, flower and strawberry were higher than vegetables and melon in solar greenhouse, of which the annual yield benefit per hectare of edible fungus was the highest-538 430.1 yuan; vegetables gained the lowest-120 046.35 yuan per hectare. The average benefit of plastic big-arch shelter was far less than the solar greenhouses, in which vegetables were 34.29% lower than in solar greenhouse, melon was 28.94% lower. The solar greenhouse is more possible to gain high efficiency than plastic big-arch shelter. The lowest proportion of high-efficiency gained by vegetables in solargreenhouse is 7.14%, while in plastic big-arch shelter is only 3.06%. Multiple crops benefits weresignificantly higher than one big crop both in solar greenhouse and plastic big-arch shelter. This paper puts forward suggestions of optimizing planting structure, reasonably arranging crops, strengthening technical training, improving crop yield and quality, exerting cooperative's advantage, and expanding sales channels.关键词
