Objective] The aim was to screen out appropriate organic fertilizer for greenhouse cultivation of Dendrobium candidum, to promote growth and increase yield.[Method] Under the same greenhouse environment conditions, the fermented sheep manure, fermented silkworm feces and fermented peanut bran were respectively applied on Dendrobium candidum plantlets.One year later, relevant traits of Dendrobium candidum plantlets in different organic fertilizer treatments were investigated and analyzed.[ Result] Applying fermented sheep manure (adding 10% potassium sulphate granulation) was more conducive to the promotion of greenhouses Dendrobium candidum plant growth, the survival rate, number of green leaves and stem nods, plant height were higher than that in treatment applied with fermented silkworm feces and fermented peanut bran.[Conclusion] Applying fermented sheep manure (adding 10% potassium sulphate granulation) is a kind of high quali-ty organic fertilizer for greenhouse cultivation of Dendrobium candidum and has the popularization value.%[目的]筛选适合铁皮石斛大棚种植的有机肥料，促进铁皮石斛的生长，使其增产。[方法]在相同的大棚种植环境条件下，分别施加发酵羊粪、发酵蚕粪和发酵花生麸对铁皮石斛种苗进行处理。1 a 后，再分别对不同有机肥处理的铁皮石斛植株相关性状进行调查与分析。[结果]施加发酵羊粪（加入10％硫酸钾造粒）更有利于促进大棚铁皮石斛植株的生长，其植株的存活率、青叶数、茎节数和株高均高于施加发酵蚕粪的和发酵花生麸的。[结论]发酵羊粪（加入10％硫酸钾造粒）是一种适合铁皮石斛大棚种植的优质有机肥料，具有推广价值。
