摘　　要：用耿进I型甘蔗种植机,研究在行下芽量相同条件下,不同行距处理对1年宿根甘蔗产量及品质的影响。结果表明,随种植行距加宽,甘蔗在株高、茎径及单茎重方面有明显提高,但宽行距种植会因下芽量减少而有效茎数相应减少,甘蔗产量则受不同程度影响。宽行距种植可增加甘蔗糖分,提高纯度,降低还原糖分。机械种植甘蔗能够有效地提高种植效率和节约成本。Effects of different row spaces on yield and quality of ratoon sugarcane under each row at the same amount of seeding bud conditions were studied by researched using Geng Jin type I sugarcane planting machine. The results showed that plant height, stem diameter and single stem weight of sugarcane were significantly increased with increasing row space width. However, effective stem was reduced as wide row spaced planting since reducing bud amount. Sugar content and purity of sugarcane were improved, reducing-sugar content was decreased as wide row spaced planting. Mechanical planting of sugarcane could effectively improve the planting efficiency and cost savings.
