【摘要】 试验选择8个代表性的甜高粱品种分别在半干旱地区、半湿润地区种植,研究两种生境对不同甜高梁品种苗期生长及成熟期农艺性状、生物产量、糖锤度的影响。结果表明:半干旱地区种植的甜高粱苗期生长速度高于半湿润地区,植株含水量低于半湿润地区;在成熟收获期,半干旱地区种植的甜高粱品种株高、茎粗均低于半湿润地区,生物产量均低于半湿润地区,茎秆含水量略有下降,茎秆糖锤度均高于半湿润地区,半干旱条件降低甜高粱的生物产量,增加茎秆汁液锤度。本试验为筛选适宜吉林省西部半干旱地区种植的甜高梁品种提供理论依据。

【Abstract】 The eight sweet sorghum varieties were used as experimental materials,which to research on growing atseedling stage and agronomic characters、biological yield、stalk brix degree of sweet sorghum at maturation stage under different habitats condition.The experimental results were as followed:the growth speed of sweet sorghum were all higher than to the control(normal habitats) and content water were all lower under semi-arid habitats at seedling stage.At maturation stage,the biomass、plant height and stalk diameter of sweet sorghum were all lower than to the control,the grain weight slightly increased,the stalk brix degree were all obviously higher than to the control under semi-arid habitats,which showed to decrease the biological yield of sweet sorghum and increase the stalk brix degree under semi-arid habitats.The experiments will offer theoretical bases to select the sweet sorghum varieties which were suitable for planting in west of Jilin province.
