中文摘要:
      【目的】研究不同配比肥料对蝴蝶兰小苗生长的影响,为培育壮苗、提高蝴蝶兰品质提供理论依据。【方法】以蝴蝶兰品种"V31"(台林红天使)小苗为试材,对比研究N:P2O5:K2O分别为30:10:10(高氮)、9:45:15(高磷)、20:20:20(等量)的花多多专用肥对蝴蝶兰小苗生长的影响。【结果】不同配比肥料对蝴蝶兰小苗生长影响显著,施用N:P2O5:K2O为9:45:15的蝴蝶兰小苗出根最快,45d即可全部出根;施用N:P2O5:K2O为20:20:20的蝴蝶兰小苗新增叶片数最多,极显著高于其他处理;施用N:P2O5:K2O为30:10:10的蝴蝶兰小苗叶冠幅最大,极显著高于其他处理。【结论】移栽后45d内用高磷肥处理,而后在根系生长良好基础上以高氮肥和N:P2O5:K2O为20:20:20肥料交替施用最有利于蝴蝶兰小苗的生长。
英文摘要:
      [Objective]Influence of different fertilizer combinations on the growth of Phalaenopsis seedlings was studied to provide theoretical references for seedling cultivation and quality improvement of Phalaenopsis.[Method]Three different fertilizer combinations viz.,N:P2O5:K2O of 30:10:10(high nitrogen fertilizer),9:45:15(high phosphorus fertilizer),and 20:20:20(equal amount)were applied to Phalaenopsis cultivar V31(Tailin Red Angel) to assess the influence of special fertilizer on the growth of Phalaenopsis seedlings.[Result]Various fertilizer combination exerted significant influence on the growth of Phalaenopsis seedlings.Amongst the three treatments,the roots of Phalaenopsis seedling grew most quickly after the application of N:P2O5:K2O of 9:45:15,in which all roots came out within 45 d.By applying N:P2O5:K2O of 20:20:20,the number of leaves of Phalaenopsis seedlings significantly increased the most compared to that of other treatments.On the other hand,by applying N:P2O5:K2O of 30:10:10,leaf canopy of Phalaenopsis seedlings was the largest,which was significantly higher than that of other treatments.[Conclusion] In order to achieve the most favorable root system growth,the Phalaenopsis seedlings should be treated with high phosphorus fertilizer within 45 d after transplantation,then alternately applied with high nitrogen fertilizer containing N:P2O5:K2O of 20:20:20.
