摘　　要：2011年在广西隆安采用田间试验方法，设置ROC22、桂糖02—901、云蔗99—91、粤糖55、福农39、桂糖32、福农30等7个基因型甘蔗问套种马铃薯处理，以不种马铃薯为对照，研究不同基因型甘蔗问套种马铃薯对马铃薯和甘蔗生长及产量的影响。结果表明：不同基因型甘蔗间套种马铃薯对甘蔗和马铃薯生长及产量未见有不良影响，却可增加马铃薯产量14000～16000kg／hm^2，比不种马铃薯收益增加42％-85％，平均62．71％。收获的马铃薯可帮助解决广西粮食紧张问题，有利于缓解蔗粮争地矛盾，增加蔗地单位面积收益，提高蔗农收入，值得在广西蔗区推广。A field experiment was conducet in 2011 on Long＇ an county, Guangxi, and seven genotypes sugarcane intereropped with potato viz.： ROC 22, GT02-901, YZ99-91, YT55, FN39, GT32, FN30, and were not interplant potato as controls （CK）, respectively, and study the effect of different genotypes sugarcane interplanting potato on growth and yield of sugarcane and potato. The results showed that the yield of different genotypes sugarcane interplanting potato on sugarcane and potato have not influenced in Latosofic red earth of Guangxi in this condition; On the other hand, it could increase production of food potato about 14 O00N16 000 kg/hm~, and could increase the income of 42%-85% than those of no plant potato, an average of 62.71%. The Harvest potatoes can solve the problems of shortage of food in Guangxi, can help to alleviate the contradiction between sugarcane and grain, and increase unit area income of sugarcane field, improve farmers income, it is worth promotion in Guangxi sugarcane area.
