摘  要:
以橡胶品种无性系PR107、RRIM600、热研7-33-97为研究对象,借助已研究建立的橡胶树精准施肥决策计算机系统和橡胶林生态系统养分循环试验数据,比较分析了基于橡胶林生态系统养分循环施肥决策系统指导施肥的经济效益和生态效益。结果表明,利用橡胶林生态系统养分循环施肥决策系统进行施肥,能促进天然橡胶增产,土壤有机质含量有所增加,胶园土壤酸化趋势得到减缓,经济效益和生态效益明显。

摘  要:
On the basis of the available precision fertilizing decision system and experimental data, rubber clones PR107, RRIM600 and Reyan 7-33-97 were selected to analyze economic and ecological benefits from their rubber plantations dressed with fertilizer based on the fertilizer recommendation from the nutrient cycle of rubber plantation ecosystem. The results showed that with this decision system for fertilizer recommendation the rubber plantations increased in yield and soil organic content, and mitigated the trend of soil acidification, resulting in obvious economic and ecological benefits.
