Comparison of Mineral Element Contents in Different Aging Rubber Trees RRIM600

This experiment studied the content of five mineral elements(N, P, K, Ca and Mg) in organs(leaf, branch, root, bark, trunk and latex) of rubber trees RRIM600. The results showed that: 1) there were differences in the content of mineral elements in organs: NKCaMgP in leaf, KCaNPMg in branch, KNMgCaP in root, Ca K N Mg P in bark, N K Ca Mg P in trunk, N K P Mg Ca in latex. The content of mineral elements from rubber trees was: NCaKMgP. 2) the content of mineral elements in different organs was: leaf root branch latex bark trunk in N, leaf branch root latex trunk bark in P, leaf branch root bark latex trunk in K, bark root branch leaf trunk latex in Ca, leaf root bark branch trunk latex in Mg. The total mineral elements in different organs was: leaf bark root branch latex trunk. 3) the linear regression established between different organs mineral contents, month age and tree age had a highly significant correlation. Leaf, branch, bark, trunk and latex of the rubber trees RRIM600 were mainly affected by the month age, but root was mainly affected by tree age. The content of N, P, K, Ca, Mg were mainly affected by the month age.
