摘要
通过比较不同基质中药用石斛生长量和有效成份质量分数,探究经过无害化处理的松材线虫病疫木在铁皮石斛(Dendrobium officinale Kimura et Migo)人工栽培中作为配方基质的使用效果.结果表明:在铁皮石斛人工种植中使用经过无害化处理后的松材线虫病疫木作为栽培基质切实可行.不同栽培方式适用的松材线虫病疫木替代基质的比例不同.以盆栽方式种植铁皮石斛时,1 号基质(V(粒径 9～12 mm疫木颗粒):V(新鲜树皮):V(饼肥)=1:1:1)充分发酵后可以在实际生产中替代常规栽培基质使用;以盘栽方式种植铁皮石斛时,3 号基质(V(疫木锯末):V(新鲜树皮):V(饼肥)=1:1:1)充分发酵后可以在实际生产中替代常规栽培基质使用.
Abstract
This study investigates the effectiveness of using treated Bursaphelenchus xylophilus disease-resistant wood as a sub-strate formulation by comparing the growth and content of effective ingredients of medicinal Dendrobium officinale grown in different substrates.The results showed that utilizing treated B.xylophilus disease-resistant wood as a cultivation substrate in the artificial planting of D.officinale is feasible.The appropriate replacement ratio of B.xylophilus disease-resistant wood substrate varies with different cultivation methods.For pot cultivation of D.officinale,the substrate formulation 1(V(dis-ease-resistant wood particles with a particle size of 9-12 mm):V(fresh bark):V(cake fertilizer)=1:1:1)can effec-tively replace conventional cultivation substrates after sufficient fermentation.In the case of tray cultivation of D.officinale,the substrate formulation 3(V(sawdust from disease-resistant wood):V(fresh bark):V(cake fertilizer)=1:1:1)can also effectively replace conventional cultivation substrates after adequate fermentation.
