摘　　要：研究适宜甘蔗套种的马铃薯最佳播种密度和栽培模式,为甘蔗套种马铃薯栽培技术推广工作提供理论依据,解决蔗区产业结构调整中出现的粮蔗争地的矛盾。采用甘蔗套种马铃薯等行距栽培三重复随机区组试验,行距为1.1 m,马铃薯株距分别为0.20 m、0.25 m、0.30 m和0.35 m,通过对试验结果进行统计分析,研究不同处理条件下甘蔗和马铃薯的经济产量及复合产值。结果表明,在该套种模式下马铃薯的小区产量随播种密度的提高而增加,最低产量为20100 kg/hm2,最高产量为27670 kg/hm2;甘蔗产量随马铃薯播种密度的加大而降低,最低产量为147510 kg/hm2,最高产量为176220 kg/hm2;套种后单位面积土地复合产值比净种条件下增加34.48%～42.24%,达到极显著水平。在甘蔗套种马铃薯等行距栽培中当马铃薯株距为0.25～0.30 m时,2种作物的产量及土地复合产值最高,经济效益最理想。For researching the optimal density and model of the sugercane interplant potato to maximize production efficiency, using the three replicated randomized block experiment for the test. The rowledge of suger was 1.1 m and the potato planting distance was 0.20 m, 0.25 m, 0.30 m, 0.35 m, respectively. The economic yield and compound production was analysis under different processing conditions. Results showed that, the potato yield increased with the increase of planting density and the output vary from 20100 kg/hm2 to 27670 kg/hm^2 Sugarcane production along with the increase of potato planting density reduced and the output vary from 147510 kg/hm2 to 176220 kg/hm2. The interplanting composite output increased by 34.48%-42.24% per unit area and reached extremely significant level. The output of two crops and land composite value was the highest at the potato planting distance was 0.25 m to 0.30 m.
