| 摘要: |
| 【目的】分析盐碱地对甜高粱含糖锤度及秸秆产量的影响，筛选秸秆产量和含糖锤度较高的耐盐甜高粱品种。【方法】以22个不同品种（系）甜高粱为试验材料，分别在正常田块（对照）和盐碱地种植，研究不同土壤对甜高粱秸秆产量和含糖锤度的影响。【结果】相同高粱品种在盐碱地的秸秆产量均低于对照，盐碱地秸秆产量较高的品种有“晋甜09-1”、“济甜杂1号”、“辽甜2号”等。同一高粱品种在不同土壤中的秸秆含糖锤度不同，盐碱地中秸秆含糖锤度在18%以上的甜高粱品种有“303A/304”、“龙甜高粱-5”、“晋甜08-1”、“辽甜6号”、“新高粱3号”，对照田块中秸秆含糖锤度在18%以上的甜高粱品种有“L0204/LTR115”、“龙甜高粱-5”、“合甜”、“晋甜08-1”、“辽甜7号”。【结论】盐碱地对不同品种甜高粱的秸秆产量和含糖锤度有明显影响，鉴于各参试品种表现出不同的特点，并未从中筛选出秸秆产量和含糖锤度高的甜高粱品种。 |

| Abstract: |
| 【Objective】The study was conducted to analyze the effect of saline soil on the yields and brixes,and to select the salt tolerant varieties with high stalk yields and high brix under saline soil condition.【Method】22 sweet sorghum varieties were cultivated in the saline soil and normal soil.The stalk yields and brixes in stems were tested.【Result】The stalk yields of a variety in saline soil were less than that in CK.The varieties of high stalk yields were Jintian 09-1,Jitianza No.1 and Liaotian No.2.;The brixes of the same variety in different soils were different.The varieties with brixes higher than 18% in saline soil were 303A/304,Longtian No.5,Jintian 08-1,Liaotian No.6,XT-2;The varieties with brixes higher than 18% in CK were L0204/LTR115,Longtian No.5,Hetian,Jintian 08-1,Liaotian No.7.【Conclusion】The saline soil caused significant difference in stalk yields and briexes of different varieties.The varieties with high stalk yields and high brix under saline soil were not selected because there were significant differences between the varieties’ physiological characters in saline soil. |
