摘　　要：以草本花卉孔雀草为试材,采用盆栽试验方法研究了用污泥堆肥、菇渣和河沙配制成不同配比的栽培基质对孔雀草生长发育的影响。结果表明:5种基质配比的物理性状均优于CK(园土);污泥堆肥和菇渣可促进孔雀草的生长发育,以T1处理(污泥堆肥40%、菇渣40%、河沙20%)和T2处理(污泥堆肥50%、菇渣30%、河沙20%)的孔雀草营养生长最好,T2处理的开花性状最优,其单株花朵数是CK的189%,花朵直径达5.53 cm,单朵花期为17.32 d,观赏期长达115 d。综合考虑基质的物理性状、孔雀草的营养生长及开花情况,T2和T1处理是适合孔雀草生长发育的较优基质,用其栽培孔雀草时花朵大且花期长,观赏期也较长。In our pot culture experiment,substrates of sewage sludge compost,mushroom residue and river sand were mixed in five proportions to study their effects on the growth and development of Tagetes erecta plants.The results showed that physical properties of the five proportions of substrate combinations all were superior to those of CK(garden soil);sewage sludge compost and mushroom residue facilitated the growth and development of Tagetes erecta plants;particularly,the vegetable growth of Tagetes erecta plants in T1(40%sewage sludge compost,40% mushroom residue and 20% river sand) and T2(50% sewage sludge compost,30% mushroom residue and 20% river sand) was the best.The superlative flowering characteristics were observed in T2,of which the number of flowers per plant was 189% of that of CK,flower diameter was up to 5.53 cm,with a 17.32 d of single flower duration and a 115 d of total ornamental duration.In sum,T1 and T2 are the better combinations for the growth and development of Tagetes erecta plants,producing big flowers,long flowering period and long ornamental duration.
