摘　　要：田间试验研究了蔗叶不同还田模式对旱地蔗园土壤水分和甘蔗产量的影响。结果表明,蔗叶不同还田模式的甘蔗产量差异不显著,蔗叶全覆盖还田与蔗叶隔行覆盖还田处理的总苗数较焚烧处理差异达极显著性水平(P<0.01),有效茎与焚烧处理差异达显著性水平(P<0.05)。蔗叶全覆盖还田与蔗叶隔行覆盖还田对宿根蔗垄上前期与后期的土壤水分保持效果较好,不同蔗叶还田模式对甘蔗行间的土壤水分保持效果较好。The experiment of different patterns of sugarcane leaf returning field was conducted to test effect on soil moisture and sugarcane yield of dry land.The results showed that the sugarcane yield under different patterns of sugarcane leaf returning field was not reached significant different.There was a significant difference（P0.01） between the sugarcane trash burning and the total seedling of sugarcane leaf returning to whole field（SLRW） as well as to alternative row（SLRA）,and there was a significant difference（P 0.05） between the sugarcane trash burning and the millable stalks.There were better effects of the both ratoon SLRW and SLRA in the period of seedling and mature on maintaining soil moisture.There were better effects of different sugarcane leaf returning field patterns on maintaining soil moisture of inter-row in sugarcane growing season.
