摘要
通过对云南橡胶园植胶土壤和橡胶树叶片微量元素含量进行测定和分析,初步拟出云南橡胶树叶片微量元素养分含量的适宜范围,其中铜12.00～13.50mg/kg,锌30.00～40.00mg/kg,铁110.00～170.00mg/kg,锰350.00～600.00mg/kg,硼18.00～35.00mg/kg和钼0.05～0.20mg/kg;同时根据云南胶园微量元素营养水平,建议对不同土壤类型的胶园开展施用钼肥和硼肥的试验研究。
The trace elements in soil and leaves of rubber plantations were determined and analyzed. It suggests that the content of trace elements in rubber leaves like Cu, Zn, Fe, Mn, B and Mo should be the range of 12.00-13.50, 30.00-40.00, 110.00-170.00, 350.00-600.00, 18.00-35.00 and 0.05-0.20mg/kg respectively. Meanwhile, experiment of different soils should be carried out to study the trace elements including Mo and B based on known data.
