摘　　要：为了使甜高粱能够在新疆地区得到推广及规模化生产,基于双因子裂区试验,种植密度为主处理(A)(设6.00万、6.75万、7.50万、8.25万、9.00万株/hm2共5个水平),6个不同甜高粱品种为副处理(B)(5个外引甜高粱品种分别为B6,B8,B12,B16和B19,对照品种为大力士(CK)),分析了不同外引甜高粱品种在新疆地区主要生物学特性的差异。结果发现,大田条件下适合推广的种植密度为6.75万株/hm2,其生物量相关性状较其他密度条件下表现较好;甜高粱品种B16在糖锤度及其他生物量相关性状方面表现最优,可作为高糖品种推广利用。To provide theoretical support for efficient cultivation techniques of sweet sorghum in Xinjiang for the large-scale production, this paper analyzed the main different characteristics of five imported sweet sorghum cultivars performing in Xinjiang, based on two factor split plot test, taking planting density as the main treatment（60 000 plants/hm^2（A1）, 67 500 plants/hm^2（A2）, 75 000 plants/hm^2（A3）, 82 500 plants/hm^2（A4）and 90 000 plants/hm^2（A5）, a total of five levels）, and taking the different cultivars as the sub-treatments five of them were introduced cultivars, as B6, B8, B12, B16 and B19, and the control was Dalishi（CK）. The result showed that the suitable planting density for promotion in Xinjiang filed conditions was 67 500 plants/hm^2, which had better biomass-related traits comparing with other planting density. The variety B16 had better performance in brix and other biomass-related traits, which could be the promoting cultivar in Xinjiang as the high-sugar variety.
