摘  要:
肿柄菊[Tithonia diversifolia(Hems1.)A.Gray.]原产墨西哥及中美洲地区,被作为观赏及绿肥植物引入我国各地栽培。目前在我国云南等省的热带、南亚热带和中亚热带地区逃逸生长并形成危害。笔者分析了海南、广东、广西、云南、福建等5省区的9份肿柄菊样品中的大量、中量和微量元素,并对其进行有机肥品质评价。结果表明,肿柄菊含有大量的氮、磷、钾等常量元素和丰富的铁、锰、铜、钼、锌、硼等微量元素,符合二级有机肥的标准。

摘  要:
Tithonia diversifolia(Hems1.) A.Gray.,native to Mexico and Central America,has long been cultivated in China as an ornamental and green manure plant.At present,it is recognized as an invasive alien species in the tropical,southern and central sub-tropical regions of China.Nine samples of T.diversifolia were collected form Hainan,Guangdong,Guangxi,Yunnan and Fujian provinces or autonomous region and their content of mineral nutrient elements analysed,based on which the quality of T.diversifolia as organic manure was assessed.The result showed that T.diversifolia contained large amounts of macro elements such as N,P and K and rich trace elements like Fe,Mn,Cu,Mo,B,and the like,and met the national standard for second class organic manure.
