移土培肥后土壤养分变化特征分析——以重庆市涪陵区移土培肥工程为例

         

摘要

说明移土培肥工程对土壤养分变化的积极影响,为今后表土剥离再利用工程提供理论支持.采取土样进行化验,并对所得数据进行对比分析.研究结果:通过对重庆市开县三峡库区移土培肥工程不同采样点土壤养分-移土培肥措施响应差异分析发现:以萝卜、白菜、花生、红薯、玉米和榨菜为代表的土地利用/覆被类型,采取移土培肥措施和未采用移土培肥措施土壤养分均有不同程度的增加,不同土地利用/覆被类型,采取移土培肥措施后土壤养分响应也有所不同.研究结论:移土培肥对工程区域土壤养分变异具有积极影响,说明以移土培肥为代表的表土剥离再利用工程具有较强的实际意义和推广价值.%To provide theoretical support for the positive impact of the shifting soil fertility project on soil, top-soil stripping for future reuse projects, soil samples for laboratory testing was collected, and data obtained were analyzed. By shifting soil fertility project in different sampling sites of soil nutrients on the the Kaixian, three Gorges reservoir area-shjft measures to respond to differences of soil fertility analysis : carrots, cabbage , peanuts, sweet potatoes , corn and mustard, as the representative of land use / cover taken to shift the soil fertility measures and did not use the shifting soil fertility measures soil nutrients have increased in varying degrees, different land use / cover types to take the shift of soil nutrients in the soil fertility measures the response is different. Shifting soil fertility has a positive impact on soil nutrient variability of the project area, the shifting soil fertility, topsoil stripping and reuse project has a strong practical significance and promotional value.
