不同肥料对铁皮石斛生长的影响

目的]筛选适合铁皮石斛大棚种植的施肥方案,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,分别采用控释肥、海藻有机液肥、控释肥+有机液肥、水溶肥+有机液肥、不施肥对铁皮石斛进行处理,分别在7和10月对铁皮石斛的相关性状进行调查与分析。结果]水溶肥+有机液肥、控释肥+有机液肥处理的成活率最高,铁皮石斛生长状况最好;不施肥处理成活率最低,长势最差。结论]水溶肥+有机液肥是一种对铁皮石斛种植较好的施肥方案,但从节约成本和劳动力角度考虑,控释肥+有机液肥较理想,具有推广价值。

Effects of Different Fertilizers on the Growth of Dendrobium candidum

Objective] The research aimed to screen fertilization scheme that suitable for planting Dendrobium candidum in greenhouses,promote the growth and increase production.Method] In greenhouse cultivation environment under the same conditions,using controlled-release fertilizer,seaweed organic fertilizer,controlled-release fertilizer + organic fertilizer,water soluble fertilizer + organic fertilizer and no fertilizer for Dendrobium candidum treatment,the related traits of Dendrobium candidum were investigated and analyzed in July and October respectively.Result]Water soluble fertilizer + organic fertilizer,controlled-release fertilizer + organic fertilizer treatment,the survival rate of Dendrobium candidum was the highest,and the growth of Dendrobium candidum was the best.No fertilizer treatment,the survival rate was the lowest and the growth was the worst.Conclusion]The water soluble fertilizer + organic fertilizer is a good fertilization program for planting Dendrobium candidum,but from the cost savings and labor perspective,the controlled-release fertilizer + organic fertilizer is ideal,and has the value of popularization.
