| In this paper, the enrichment coefficient of nutrient elements in the soil was compared between RRIM600 and RY 7-33-97 rubber trees, to provide valuable reference for the rubber plantation management. The results showed that the enrichment coefficient of each organ and nutrient content, were the highest in leaves and the lowest in trunk.Meanwhile, there was difference of the enrichment coefficient for different nutrient elements, shown as N>K>P, and the enrichment coefficient also changed differently with ages and months. The enrichment capacity of rubber tree RY7-33-97 for nutrient elements was stronger than that of RRIM600. |
