摘要
为研究不同配比污泥与园林废弃物堆肥产品混合施用对香水百合生长、开花和土壤改良的影响,以北京市城市污泥和园林废弃物为研究对象,采用盆栽试验,设置7种处理均为添加20%的堆肥产品混合物(处理1至处理7污泥所占比重分别为:0%、100%、90%、80%、70%、60%、50%),以纯壤土为对照,比较了其对栽植香水百合(Lilium casa blanca)后盆栽土壤的改良作用和对植物的影响。结果表明:混合施加后香水百合能够有效吸收大量养分,有利于其生长和开花,也有助于改善土壤pH值,其中,处理6和处理7效果最好。
This paper is to study the effects of mixed application of different proportioning sludge and garden waste composting products on the growth,flowering of Lilium casa blanca and soil amendment. This paper takes Beijing urban sludge and garden waste as the research objects,and adopts the pot experiment. Seven treatments are set up and all of them add 20% compost product mixture (The proportion of sludge from treatment one to seven is:0% 100%,90%,80%,70%,60%,50%). Using pure loam as a control,it compares the improvement effect on the potted soil after planting Lilium casa blanca and its effects on plants. The results showed that the perfume lily can effectively absorb a large amount of nutrients after mixed application,which is beneficial to its growth and flowering,and also good for soil pH. Among them,treatment six and treatment seven have the best effect.
