贵州省旱坡地甘蔗品种比较试验 　　摘要：2012-2013年，用黔蔗06/212、黔蔗06/156、黔蔗06/89、桂糖96/211、云蔗03/45、德蔗03/83和桂糖11号（CK）进行旱坡地新植和宿根品种比较试验。结果表明，6个参试品种均优于CK，与CK相比，各品种蔗茎产量、蔗糖分和单位面积含糖量分别增加了10.71%～50.86%、1.0～2.7个百分点和18.41%～64.02%。其中，桂糖96/211、德蔗03/83和黔蔗06/212表现较佳，蔗茎产量分别达102.51、112.38和109.10 t/hm2，分别比CK增产37.62%、50.86%、46.46%；蔗糖含量分别达17.37、17.24和17.19 t/hm2，分别比CK增加64.02%、62.80%、62.32%，达到了每667 m2吨糖的技术指标，可作为贵州省旱坡地优良甘蔗品种推广应用。 　　关键词：甘蔗品种；品种比较试验；旱坡地；贵州省 　　中图分类号：S566.1 文献标识码：A 文章编号：0439-8114（2016）19-5001-03 　　DOI：10.14088/j.cnki.issn0439-8114.2016.19.025 　　Abstract： Using Qinzhe06/212，Qinzhe06/156，Qinzhe06/89，Guitang96/211，Yunzhe03/45，Dezhe03/83 and Guitang11（CK） as materials，the variety comparison test of planting cane and ratoon cane in the upland slope field was conducted in 2012 to 2013. The results indicated that，six test varieties were more superior than CK，sugarcane stalk yield was 10.71% to 50.86% higher than CK，sucrose ratio was 1.0 to 2.7 percentage points higher than CK，sucrose content was 18.41% to 64.02% higher than CK. Guitang96/211、Dezhe03/83 and Qianzhe06/212 showed better comprehensive characters than CK，sugarcane stalk yield was 102.51 t/hm2，112.38 t/hm2 and 109.10 t/hm2，and increased by 37.62%，50.86%，46.46% respectively compared with the control；sucrose content was 17.37 t/hm2，17.24 t/hm2 and 17.19 t/hm2，and increased by 64.02%，62.80%，62.32% respectively compared with the control. The yield of these three varieties achieved the technical indicators of 15 t/hm2，and could be popularized and utilized in the upland slope filed in Guizhou province. 　　Key words： sugarcane varieties；comparative test of varieties；the upland slope filed；Guizhou province 　　贵州省是全国甘蔗主要产区之一，近年来，随着中国甘蔗产业重心由沿海经济发达区向中西部区转移，给贵州省甘蔗产业发展带来了机遇。根据贵州省“十二五”制糖产业发展规划，全省甘蔗种植面积将达7.33万hm2。但是，贵州省甘蔗产区主要位于南、北盘江和红水河流域，以旱坡地种植甘蔗为主，旱坡甘蔗地面积占总种植面积的90%以上[1]，示范推广旱坡地良种及配套技术是贵州省蔗糖产业需要迫切解决的问题。品种是甘蔗生产中的关键因素，其对增产、增糖的贡献率可高达30%[2]。为了适应贵州省蔗糖产业的发展需要，作者于2010年以来，从广西、云南、广东等引进优良甘蔗品种（系）30余个进行鉴选，根据前期研究，从自育及引进的优良甘蔗品种（系）中筛选出6个优良品种[3，4]，于2012-2013年进行旱坡地
