堆肥大腸桿菌群在土壤與小白菜中之存活

, 2014
摘要 近年有機資材的使用大幅增加，處理不當的有機肥料中可能含有大量的病原細菌，經施用後有可能會影響到農作物上。因此，本研究主要是觀察大腸桿菌群在不同的施肥處理下土壤中的存活情形以及傳播至作物之現象。首先選擇農試所35號田長期施用不同肥料處理之試驗田，調查土壤中大腸桿菌群之數量，以本研究篩選之大腸桿菌群之ㄧKlebsiella sp.當作試驗用菌進行實驗室土壤中之孵育試驗，添加於兩種金門紅土與農試所沖積土中分析觀察其存活情形。為探討不同氮源對Klebsiella sp.之影響 ...

基于GIS与RUSLE的武陵山区小流域土壤侵蚀评价研究

, 2011
以长江中下游武陵山区女儿寨小流域为研究区,基于数据观测积累及实地调查采样等方法,计算了研究区降雨侵蚀力、土壤可蚀性等因子,运用GIS与RUSLE评价了流域土壤侵蚀强度并分析了其与土地利用方式、海拔高度的关系。结果表明,流域平均土壤侵蚀强度为788.44t/(km2.a),属微度侵蚀,流域面积95.18%的范围发生轻度以下的侵蚀,强烈以上侵蚀仅占1.19%。从土地利用类型来看,耕地、果园侵蚀强度较大,均达到中度侵蚀,有林地除竹林地为轻度侵蚀外均属微度侵蚀,耕地、果园、竹林地是今后水土流失防治的主要地类 ...
