摘　　要：为探明海南省冬季橡胶林下套种马铃薯是否可行,对林下套种马铃薯进行产量和品质初评;并对不同种植密度马铃薯长势和产量进行分析。结果表明:海南冬季橡胶林下套种马铃薯品种合作88折合净种产量为25 983.90 kg/hm2,与云南勐海净种差异不显著,而丽薯6号产量为20 155.35 kg/hm2,显著高于勐海净种;胶林下套种可显著提高合作88干物质含量;合作88适宜套种密度为株距20 cm,行距30 cm,丽薯6号适宜套种密度为株距30 cm,行距30 cm。说明海南冬季橡胶林下套种马铃薯存在较大可行性,这为橡胶林下复合种植提供新的模式。Potatoes were intercropped with different planting densities in rubber plantations in winter, and their growth vigor and yield were determined and analyzed to select an optimum planting density for potatoes intercropped in the rubber plantations. The results showed that the potato varieties C88 and Lishu No.6 yielded 25983.90 kg/hm2 and 20155.35 kg/hm2 in rubber plantations, respectively, which were not significantly different from those of the potatoes intercropped in Menghai County, Yunnan Province. The dry matter content of potato variety C88 was increased in the intercropping system. The best intercropping densities for C88 and Lishu No.6 were 20 cm （plant spacing） ×30 cm （row spacing） and 30 cm ×30 cm. This indicates a good feasibility of intercropping of potatoes in the rubber plantations in winter in Hainan.
