大花蕙兰不同器官内不同时期各营养元素相关性分析

Analysis of Correlation about the Various Nutrient Elements of the Diffrenent Organs for Cymbidium hybridum in the Different Periods

[目的]研究大花蕙兰的营养特性。[方法]对大花蕙兰不同器官内不同时期各种营养元素的含量进行了测定,并进行了相关性分析。[结果]钾元素4个时期在叶片与假鳞茎内的含量均有极显著相关,其余元素的含量由于时期的不同相关性也不同。此外,不同元素间的相关性主要集中在初花期。[结论]在研究大花蕙兰钾元素含量时可以只采叶片作为研究对象,其余营养元素含量只能采用整株式采样法。

[Objective]The aim was to research the nutritive characteristics of Cymbidium hybridum.[Method]The content of the various nutrient elements of the different organs for Cymbidium hybridum in the different periods were mensurated and the correlation about them was analysed.[Result]There was a significant correlation between the content within the leaves and the bulbs for Potassium element in the four periods and the correlations were different for the other elements in the different periods.In addition,the correlation between the different elements concentrated in the early flowering stage.[Conclusion]The leaves could be used as the material for studying the content of Potassium in Cymbidium hybridum and the rest elements could only use the whole plant nutrient content-type sampling.
