Study on Mineral Elements Content and Change in Macadamia ternifolia Leaves during the Development Period
摘要
Abstract
Objective] To investigate the contents and dynamic variation characteristic of mineral elements in Macadamia ternifolia leaves dur-ing the growth period.[Method] Taking H2, OC, 788 which were the main cultivated M.ternifolia varieties in Guizhou Province as the study object, mineral elements content and variation law were determined.[Result]The results showed that the contents of 7 kind of mineral ele-ments indicated regular change in the leaves of three M.ternifolia varieties.The order of mean content of nutrient elements from large to small was N, Ca, K, P, Mg, Fe, Cu.The contents of N, P, K, Ca, Fe in OC variety were higher than that in H2 and 788 species.The contents of N and Mg in the leaves were increased gradually;the content of P firstly increased, then decreased; K contents of M.ternifolia leaves de-creased and then increased; the quantity of Ca in leaves was decreased;Fe contents change presented inverted "V"type, and had a big change range;the contents of Cu showed the "V"type change.The contents of P and Cu change reached extremely significant negative corre-lation, while significant negative correlation existed between Ca and Mg contents.[ Conclusion] The study can provide theoretical guidance for rational fertilization of M.ternifolia in Guizhou Province.关键词
