【摘要】 通过在工程化草坪生产基地设置污泥发酵产物施用处理,对在草坪应用的杂草问题进行了深入分析。结果表明,污泥发酵物料的掺入增加伴生杂草总量2.92～6.67倍。主要伴生杂草种类为牛筋草(Eleusine indica(Linn)Gaertn),与对照相比,污泥发酵物处理的牛筋草密度增加0.84～1.67倍;种籽主要来自于污泥物料。适当增加施用深度和预喷施除草剂可显著降低伴生杂草密度约50%。更多还原

【Abstract】 Weed is analysized during composted sewage sludge being applied in large scale sod substrate production.Results indicated that quantity of associated weed brought by input of composted sewage sludge to sod substrate was increased 2.92 to 6.67 times compared with control treatment.Eleusine indica(Linn) Gaertn is identified as main specie of associated weeds,composted sewage sludge amended treatment increased 0.84-1.67 times comparison to control.Moreever,the seed is dedueced to derive from sewage sludge itself.Properly increasing the depth of application and the spraying of herbicides significantly reduced about 50% weeds density.更多还原
