摘要
对热研7-33-97和RRIM600橡胶树对土壤中营养元素的富集系数进行比较研究,结果表明:(1)橡胶树各器官富集系数与养分含量均为树叶最高,树干最低;(2)橡胶树对各营养元素的富集系数大小有差异,表现为N>P>K;(3)橡胶树对养分的富集系数表现出不同的年变化和月变化特征;(4)热研7-33-97橡胶树对养分的富集能力强于RRIM600。
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.
