鹅不食草生育期矿质元素变化研究
Study on the Change of Mineral Element Contents in Centipeda minima during the Development Period
摘要
Abstract
In order to provide a scientific basis for fertilization,the principle of quantity demand of mineral elements in Centipeda minima during the development period was studied.Mineral element contents of 8 periods in C.minima were tested and the data were analyzed.Mineral elements in C.minima changed obviously during growth period.Potassium is the most abundant element in C.minima,and the descending order of mineral element contents was N,P,Ca,Mg,Fe,Mn,Zn and Cu.C.minima has higher contents of N,Ca,Mg and Zn on the early growth stage,the highest P content on full-bloom stage,and relatively higher contents of P,Mg,Fe and Mn on fruiting stage.Moreover,there were significant negative relationships between K and P and between N and Mn,and significant positive relationships between Zn and Ca or Mg.The kind of elements needed differed between different development periods.Meanwhile,attentions also should be payed to synergistic or antagonistic effect when to fertilize.关键词
