摘要

摘要: 为了筛选出适宜在平安地区种植的最佳小黑麦种质，以小黑麦品种中饲1048为对照，甘农2号、石大1号、甘农4号和小黑麦新品系C 25、ZHS 811为试验材料，通过研究其在青海省平安地区的生产性能（草产量、株高、枝条数）和营养品质（可溶性糖、酸性洗涤纤维、中性洗涤纤维、粗蛋白）,并采用灰色关联度法进行综合比较，筛选出最佳种质。结果表明，通过对参试小黑麦种质的生产性能进行比较，C 25的干草产量（10.20 t/hm²）除了与ZHS 811的干草产量（8.66 t/hm²）间无显著差异外，显著高于其他4个种质；石大1号株高（97 cm）最高，除了与ZHS 811无显著差异外，显著高于其他4个种质；对照中饲1048枝条数（340万枝/hm²）最少，显著少于其他5个种质。通过对参试小黑麦种质营养品质进行比较，甘农4号的CP含量（15.35%）最高，显著高于其他5个种质；ZHS 811的SS含量（9.06%）最高，显著高于其他5个种质；甘农2号的ADF（22.41%）含量除了与甘农4号ADF（23.82%）含量间无显著差异外，显著低于其他4个种质；甘农2号的NDF（40.98%）含量最低，显著低于其他5个种质。通过对参试小黑麦种质的生产性能和营养品质进行综合评价，小黑麦品系C 25、ZHS 811综合排名靠前。研究表明，小黑麦品系C 25、ZHS 811适合在平安地区生长和种植，品系ZHS 811由于可溶性糖的优势，比较适合作为青贮饲料，对照中饲1048不适合在平安地区种植。

Abstract: In order to screen the best triticale germplasm suitable for planting in Ping’an area, the triticale variety Zhongsi 1048 was used as the control, Gannong No.2,Shida No.1, Gannong No.4, and the new triticale strains C 25, ZHS 811 were used as experimental materials. By studying its production performance（grass yield, plant height, number of branches） and nutritional quality（soluble sugar, acid detergent fiber, neutral detergent fiber, crude protein） in Ping’an area of Qinghai Province, and using the gray correlation method for comprehensive comparison, the best germplasm was selected. The results showed that by comparing the production performance of the tested triticale germplasm, the hay yield of C 25（10.20 t/hm~2） was significantly higher than that of the other four germplasm except that there was no significant difference between C 25 and ZHS 811（8.66 t/hm~2）; Shida No.1（97 cm） had the highest plant height, which was significantly higher than that of the other four germplasms except for no significant difference from ZHS 811. Zhongsi 1048 had the lowest number of shoots(3.4 million branches/hm~2, which was significantly less than that of the other 5 germplasms. By comparing the nutritional quality of the tested triticale germplasm, Gannong No.4 had the highest CP content（15.35%）, which was significantly higher than the other five germplasm; The SS content of ZHS 811（9.06%） was the highest, which was significantly higher than that of the other five germplasm; The ADF content of Gannong No.2（22.41%） was significantly lower than that of the other four germplasm except that there was no significant difference between Gannong No.2 and Gannong No.4（23.82%）; The NDF（40.98%） content of Gannong No.2 was the lowest, which was significantly lower than that of the other five germplasms. Through the comprehensive evaluation of the production performance and nutritional quality of the tested triticale germplasm, the triticale strains C 25 and ZHS 811 ranked high.Study showed that the triticale strains C 25 and ZHS 811 are suitable for growth and planting in Ping’an area, and the strains ZHS 811 were more suitable for silage due to the advantages of soluble sugar, control Zhongsi 1048 were not suitable for growing in the Ping’an area.
