中文摘要	为筛选出适宜在甘肃山旱地区种植的饲用甜高粱(Sorghum bicolor)品种,以丰富当地饲草料资源,支撑草食畜牧业的发展,以15份甜高粱品种(系)为材料,采用随机区组试验,对不同品种(系)在该地区的产草量及营养价值进行测定分析,并采用隶属函数法对其综合生产性能进行评价。结果表明,各品种(系)间的粗蛋白(CP)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、可溶性糖(WSC)和总可消化营养物(TDN)含量均存在显著差异(P < 0.05),各品种(系)间除ADF含量和TDN含量的排序基本一致外,其他养分含量在各品种(系)间排序无规律;其中CP含量以辽甜3号最高,为7.61%;NDF含量以晋甜杂3号最低,为47.90%;ADF含量以辽甜1号最低,为27.70%;WSC含量以2018 JT-7最高,为27.77%;TDN含量以辽甜1号最高,为62.50%。各品种(系)间的干物质(DM)产量存在显著性差异(P < 0.05),以晋甜杂3号最高,为20.63 t·hm~(-2)。品种(系)间CP产量差异不显著(P > 0.05),以壮牧79 141最高,为1.31 t·hm~(-2); TDN产量差异显著(P < 0.05),以晋甜杂3号最高,为12.67 t·hm~(-2)。将各品种的DM产量、CP、 WSC、NDF和ADF含量用模糊数学隶属函数综合评价,结果表明,品种(系)晋甜杂3号、2018JT-7和辽甜3号的综合生产性能较优,适宜在该地区推广种植。
英文摘要	This study aimed to determine the most suitable sweet sorghum varieties in the dry farming area of Gansu province to enrich local forage resources and to support the development of herbivorous animal husbandry. Fifteen sweet sorghum varieties were selected for the randomized block experiment to analyze the variance of the yield and nutritional quality. The membership function method was used to evaluate the comprehensive production performance. The results showed that the content of CP, NDF, ADF, WSC, and TDN were significantly different among the varieties/lines (P < 0.05). The sequence of nutrient contents was irregular among varieties, except for ADF and TDN, which were consistent. The highest content of CP and TDN were found in Liaotian 3 (7.61%, 62.50%), respectively and the highest content of WSC was found in 2018 JT-7 (27.77%). The lowest content of NDF and ADF were found in Jintianza 3 (47.90%) and Liaotian 1 (27.70%), respectively. There were significant differences in dry matter yield among varieties (lines). The highest dry matter yield was 20.63 t·ha~(-1), in Jintianza 3. CP yield difference between varieties was not significant with the highest yield, 1.31 t·ha~(-1), in Zhuangmu 79141; TDN yield difference between varieties was significant (P < 0.05) with the highest yield, 12.67 t·ha~(-1), in Jintianza 3. The DM yield and the content of CP, WSC, NDF, and ADF were evaluated by the membership function method using fuzzy mathematics. As a result, Jintianza 3, 2018 JT-7, and Liaotian 3 were the most suitable varieties in this arid region, as they had the best integrated production performance.
