| 摘 要： | 中国盐碱地资源丰富但利用率低，小黑麦作为抗逆性强、饲用价值高的作物具有重要开发潜力。本研究旨在通过全生育期耐盐鉴定的方法，筛选出适合盐碱地种植的小黑麦资源，以期为盐碱地的农业发展提供新的思路。本研究选取了48份小黑麦资源，针对耕层土壤盐分分布不均的问题，采取了少量多次滴灌的方式，将鉴定期内耕层盐分含量控制在约0.7%。随后对小黑麦的存活率、鲜重、干重及田间综合表现进行系统比较，并结合当前常用的五级评价标准，筛选出9份综合表现良好的小黑麦资源，具体为HS-006、HS-518、HS-476、HS-004、HS-520、HS-541、HS-447、HS-530和HS-139。这些资源不仅具有较强的耐盐能力，还展现出丰富的生物量，表明其在盐碱地的种植潜力。本研究旨在强调采用科学的土壤盐分调控方法对于植物资源的筛选至关重要，小黑麦资源鉴定结果为后续的品种培育和推广提供了可靠的基础。 |

| Abstract: | China possesses abundant resources of saline-alkali land; however, its utilization rate remains low. Triticale, known for its strong resistance to adversity and high forage value, presents significant development potential. This study aims to identify triticale resources suitable for cultivation in saline-alkali land through a method of salt-tolerance identification conducted throughout the entire growth period, thereby providing new insights for agricultural development in these regions. In this research, 48 triticale resources were selected. To address the issue of uneven soil salinity distribution within the plow layer, a strategy of minimal yet frequent drip irrigation was employed to maintain an approximate salinity level of 0.7% during the identification period. Under this condition, systematic comparisons were made regarding survival rates, fresh weight, dry weight, and overall growth performance of triticale resources. Using a widely adopted five-level evaluation standard, nine triticale resources with better comprehensive performance were obtained: specifically HS-006, HS-518, HS-476, HS-004, HS-520, HS-541, HS-447, HS-530 and HS-139. These selected resources not only exhibited high salt-tolerance but also demonstrated strong biomass production potential—indicating their viability for cultivation in saline-alkali land. This study underscores the critical importance of employing scientific methods for soil salinity regulation when screening plant resources. The identification results obtained from this research provide a reliable foundation for subsequent variety breeding and promotion efforts. |
