【摘要】 [目的]为了研究堆肥对破坏土壤的修复作用。[方法]利用污泥好氧静态堆肥装置生产的堆肥对月季、杨树、油松等花卉树木及草坪进行了栽种施用的对比试验。[结果]草坪草施用污泥,其生物量增加,绿期延长。堆肥施用于观赏性植物月季,花卉的开花量增加,花径增大,花期延长。施用污泥1年后,杨树、泡桐和小油松的树高和地径比对照增长了9.2%~41.2%和5.6%~20.8%。[结论]堆肥对树木生长具有良好的效果,且对土壤修复具有很好的效果。更多还原

【Abstract】 [Objective] The aim was to study the repairing effect of compost on destroyed soil.[Method] The comparison experiment on planting and application of flowers,trees and lawn such as China rose,poplars and pines were conducted with compost produced by aerobic sludge composting device.[Result] The lawn using sewage sludge increased biomass and green stage.When compost was applied in ornamental China rose,its blossom quantity,flower diameter and flower stage were increased.After using sewage sludge for 1 year,the tree-heights and ground-diameters of poplar,paulownia and little Chinese pine were increased by 9.2%～41.2% and 5.6%～20.8% than that of CK.[Conclusion] Compost had a good effect on tree growth and soil reparation.更多还原
