橡胶林钾素研究进展

综述国内外橡胶林钾素相关研究,指出在橡胶林生态系统中,钾的来源途径主要包括土壤、降水、枯枝落叶归还和人工施肥等,输出途径主要为采胶、采种、淋溶损失和水土流失,针对当前胶林系统内钾素养分失衡的现状,对橡胶林钾素循环进行系统动态模拟研究,实现养分循环理论研究与指导施肥的有机结合仍是今后研究的重点。

Advances in Study of Potassium Functions under Rubber Plantations

On the basis of domestic and international research results,we know that the potassium of the rubber plantation ecosystem mainly originated from soil,precipitation,the return of litter fall and artificial fertilization,and the major form of nutrient export including rubber latex,rubber seed,leaching loss and soil erosion.At present potassium nutrient is out of balance,the author points that it is necessary to make a comprehensive and systematic study on the potassium cycle of the rubber plantation and the system dynamics simulation.It is important that combination of the nutrient cycle theory and guide-based application of fertilizers.
