三个桂花品种生长量、花量及叶片矿质营养含量变化研究

Studies on the Increment,Flower and Mineral Nutrient Change of Three Cultivars of Osmanthus fragrans Lour

  • 摘要: 以桂花(Osmanthus fragrans Lour)品种‘柳叶银桂’、‘四季桂’和‘山桂’为试材,对其生长量、花量及叶片矿质营养含量的变化进行了分析。结果表明:(1)‘柳叶银桂’、‘四季桂’和‘山桂’的总生长量和鲜花产量差异显著,总生长量为‘柳叶银桂’>‘山桂’>‘四季桂’,而全年鲜花产量为‘柳叶银桂’>‘四季桂’>‘山桂’。(2)不同元素年周期变化不同,K、Ca、Mg、Fe、Cu均呈单锋曲线,K、Ca、Cu峰值出现在4月,Fe和Mg峰值出现在8月;N、P含量的年变化呈双峰曲线,峰值出现在4月和10月。Mn和Zn分别有单峰和双缝两种不同的变化趋势。

     

    Abstract: Three cultivars of sweet Osmanthus,Osmanthus fragrans ‘Liuyeyingui’,‘Shangui’ and ‘Sijigui’ were studied on the increment,flower output and the change of mineral nutrient.The results showed:(1)The differences of total increment and flower output were remarkable among these three cultivars.They ranged in total increment from‘Liuyeyingui’ to ‘Shangui’ to ‘Sijigui’,while in flower output per year were from ‘Liuyeyingui’ to ‘Sijigui’ to ‘Shangui’.(2)The content of different mineral had changed differently.K,Ca,Mg,Fe,Cu appeared a change of a single peak:the content of K,Ca,Cu reached the peak value at April while Fe and Mg at August;the annual changes of the content of N and P had two peak value at April and October.On the other hand,Mn and Zn changed differently with a single peak and a double peak respectively.
