Effects of Different Cropping Systems on Soil Quality
摘要
Abstract
[Objective] The aim was to explore the soil properties change in the process of field crops into greenhouse vegetables and their possi ble adverse effects on the environment. [Method] Fertilization,irrigation,crop growth conditions and soil quality changes in the major cropping systems (greenhouse monoculture,greenhouse rotation and open field rotation) in Chongming Island,Shanghai were investigated from 2007 to 2009. [Result] Different cropping systems significantly affected soil quality. Soil organic carbon,mineral nitrogen,available phosphorus and ex changeable potassium content increased in greenhouse cultivation compared to open field rotation due to excessive application of irrigation and fer tilizers. Soil pH values decreased by 0.6 and 0.4 in the greenhouse monoculture and greenhouse rotation,respectively,while did not significantly change in open field rotation. Meanwhile,greenhouse cultivation significantly increased soil EC,and N03- and Cl- contents,which showed an in creasing trend with the planting years increase. However,the salt content changes were not significant in open field rotation. [Conclusion] High cropping index,excessive fertilizer input and inappropriate fertilization and irrigation resulted in greenhouse soil quality degradation due to weak farmer's skill and local extension services.关键词
