污泥堆肥在花卉栽培中的应用研究

Sludge Compost to Be Used in Flower Cultivation

借助污泥堆肥的方法,将污水厂脱水后的污泥作为肥料用于园林花卉的栽培,为解决污水厂剩余污泥的出路,避免二次污染,探索出一条有效途径。通过对污泥高温腐熟、干化,将其配制成不同营养土,分别在小苍兰、一串红、瓜叶菊上进行筛选和试验研究。结果表明,不同配比营养土对小苍兰的生育和切花的产量与品质均有明显的影响。

With the sludge composting method,according to local conditions,the sludge can be used as fertilizer for the garden flower cultivation.This experiment is focus on to find a effective way for the thickened sludge and avoid it to make a secondary pollution.Firstly,the dewatered sludge are being converted to compost,during this period,the heat will be released,killing pathogens and eggs.Secondly,make a different configuration of the compost.And thirdly,have research on freesia,scarlet sage and cineraria.The results showed that different configuration of the compost have a clear implication on the freesia＇s seeding and burgeon.
