摘　　要：在云南山地胶园,对缺氮(镁)型、缺氮钾(镁)型橡胶树开展专用肥施用效果研究。3 a试验结果表明:与常规施肥相比,施用高氮(镁)型、高氮钾(镁)型橡胶树专用肥,单位面积年平均干胶增产率分别为8.63%、9.69%;年平均增产干胶70.37、96.04 kg/hm2;减少肥料投入891、679元/hm2,产生经济效益分别为2 298、2 600元/hm2;橡胶树茎围分别增长6.78%、10.79%;橡胶树叶片N、Mg含量增加,K、Ca含量在正常值范围内。对症施用橡胶树专用肥比常规施肥增产效果好、肥料投入少、经济效益高,改善了橡胶树叶片营养状况,促进橡胶树生长。The effects of rubber tree special fertilizer application on rubber trees of nitrogen（magnesium） deficiency type and nitrogen potassium （magnesium） deficiency type in mountainous rubber plantation of Yunnan province were studied in the past three years. The results showed that compared with rubber trees with regular fertilizer application, the dry latex of nitrogen （magnesium） high type and nitrogen potassium magnesium high type per unit area had increased 8.63% and 9.69%, respectively, that were 70.37 kg/hm^2 and 96.04 kg/hm2, while the fertilizers input had reduced by 891Yuan/hm^2 and 679 Yuan/hm^2; and economic returns were 2 298 Yuan/hm^2 and 2 600 Yuan/hm^2, respectively, the growth rate of stem thickness were 6.78%and 10.79%. The content of N, Mg in rubber tree leaves had increased, whereas the content of K, Ca in rubber tree leaves were within normal value. Applying rubber special fertilizers based on the diagnosis had a better effect on rubber yield increase than regular fertilizer application, it also helped reducing fertilizer input with high economic returns, improving nutritional status of rubber tree leaves, promoting growth of rubber tree.
