为实现城市生活污泥的资源化利用,本文通过盆栽试验,测定不同基质处理香樟的多项生长指标,对以城市生活污泥好氧堆肥为主的香樟专用基质配伍开展研究。结果表明,相较于菌菇渣,城市生活污泥堆肥更适合作为香樟的有机肥源;维生素B12、微量元素B、Zn配合施用,比萘乙酸更能促进香樟的恢复生长;杀菌剂对于香樟专用基质功效存在负作用;在11个不同配伍处理中,E处理(城市生活污泥堆肥+复合肥+维生素B12+微量元素B、Zn+聚天冬氨酸)基质配伍最好,其综合评价最高,在香樟8个单项生长指标中,5个指标排在前两位。研究结果将为香樟专用基质的开发提供理论和实践依据。
In order to realize the utilization of municipal sewage sludge, pot experiments were carried out to determine the growth indexes of camphora in different substrates. The compatibility of camphora root-specific substrate with aerobic composting of municipal sewage sludge was studied. The results showed that compared with mushroom residue, composting of municipal sludge was more suitable as organic fertilizer source for camphora; vitamin B12, trace elements B and Zn could promote the recovery of camphora more than naphthalene acetic acid. There was a negative effect on the efficacy of the camphor-specific substrate. In the 11 different compatibility treatments, the compatibility of E treatment (MSW + B + B12 + Zn + Evaluation highest, camphor 8 single growth indicators, five indicators in the top two. The results will provide theoretical and practical basis for the development of camphor-specific matrix.
