摘要
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。
To realize resource utilization of municipal sewage sludge,with the aerobic composting of municipal sewage sludge as the main raw material,the formula ratio of camphor seedling has been optimized by the different kinds of growth indicator of camphor seedling in pot.The results show that：comparing with mushroom residue,municipal sludge compost was suitable as organic part of formula for camphor seedling;the combination of vitamin B12,microelement B and Zn,was of better effect on camphor growing,made a good substitute for 1-naphthlcetic acid;antiseptic played a negative role in the special matrix for camphor growing;the E treatment（aerobic composting of municipal sewage sludge＋ compound fertilizer＋ vitamin B12＋trace elements（B,Zn）＋polyaspartic acid）was the most suitable formula of camphor seedling which had five kinds of growth indicator of camphor seedling ranking top two between the eleven ratio;the comprehensive evaluation index system also supported the conclusion.
