甘蔗糖业在广西的工农业生产中占有重要的地位，是广西经济的支柱产业之一，玉米也是广西种植面积较大的作物。甘蔗地间种玉米可以增加复种指数，增加单位面积的经济效益，在人多地少的广西尤为重要。为解决玉米与甘蔗争地的矛盾，找出一种甘蔗间种玉米的最佳模式供生产上应用，进行了玉米12000、15000、18000、21000、24000株/hm2等5种不同种植密度及种植方式的比较试验。结果表明，玉米种单穴单株比种单穴双株的产量高。玉米密度越大，甘蔗产量越低，以21000株/hm2的密度总体效益最好。

The sugar industry plays an important role in the industrial and agricultural production in Guangxi, is one of the pillar industries of Guangxi's economy, and corn is also planted in great area in Guangxi. Sugarcane fields interplanted with other crops can increase the multiple crop indexes and increase economic benefits per unit area. It is particularly important in densely populated Guangxi with insufficient farmland. To resolve the contradiction between corn and sugarcane and find the best model of sugarcane fields intercropped with maize for production applications, comparative experiments of maize in different planting density and planting patterns were conducted. Results showed that planting maize with single point per plant is better than single point double plants, the density of 1400 plants/acre is the best.
