生物干化污泥用作鸡冠花栽培基质的试验研究

Experimental Study on Biological Drying Sludge Used as Celosia cristata L. Substrate

以经过无害化处理的生物干化污泥为原料,研究不同生物干化污泥比例对鸡冠花生长的影响。结果表明:不同比例的生物干化污泥对鸡冠花的生物特性影响显著。生物干化污泥为25%(质量百分比)的混合基质在化学性质和营养元素含量等方面都符合理想基质的要求,对促进鸡冠花生长的效应最大。

Taking the safe disposal of biological drying sludge as raw material,the effect of different proportions of biological drying sludge on growth of Celosia cristata L.were studied in this paper.The results showed that effects of physiological parameters of Celosia cristata L.on different proportions of biological drying sludge were significant.The proportions of biological drying sludge at 25 %（mass percent）,whose chemical properties and nutrient content were in line with the requirements of the ideal substrate,could be the most significant for the growth of Celosia cristata L.These provided experimental basis for the promoting the application of biological drying sludge to gardens and floriculture.
