以紫茎泽兰沼渣制作腐殖酸肥料的实验研究

Study on Production of Humic Acid Fertilizer from Fermented Residue of Crofton Weed

以制作农残降解剂后紫茎泽兰的残渣残叶为原料,通过对其进行不同TS浓度的发酵实验,探究其适用于发酵的最佳浓度;并对发酵后沼渣的氮、磷、钾、腐殖酸等成分进行测定。结果表明,TS浓度为11.25%时产气较多;残渣腐殖酸含量与市场腐殖酸复合肥相近,但氮、钾元素相比含量较少。该实验可以为资源化利用紫茎泽兰、制作新型腐殖酸肥料提供参考依据。

In this paper,the residue leaves of Crofton Weed after the production of agricultural degradation agent can be used as raw materials.Through the fermentation experiments of different TS concentration,the optimum concentration for fermentation is explored.The nitrogen,phosphorus,potassium,humic acid and other components of the fermented residue were determined.The results showed that gas products more when TS concentration was 11.25%,and the content of humic acid in residue was similar to that humic acid compound fertilizer in market,but the content of nitrogen and potassium was less.This experiment can provide a reference for the resource utilization of Crofton Weed and the production of new humic acid fertilizer.
