摘      要：为了筛选饲用小黑麦资源,并更贴近盐碱地的种植环境,本研究采用全生育期耐盐鉴定方法,对48份小黑麦资源进行了耐盐性鉴定。针对耕层土壤盐分分布不均的问题,本研究采取了少量多次滴灌的方式,将耕层盐分含量控制在约0.7%。随后,比较了小黑麦的存活率、鲜重、干重及田间综合表现,并结合当前常用的五级评价标准,从中筛选出9份综合表现良好的资源,具体为冀饲6号、HS518、HS476、冀饲4号、HS520、HS541、HS447、HS530和HS139。这些小黑麦资源具有较强的耐盐能力和丰富的生物量,因而适宜进一步推广种植。In order to evaluate the salt tolerance of forage triticale resources suitable for growth in saline-alkali soils, we identified the salt tolerance of 48 triticale resources throughout their entire growth period. To address the issue of uneven soil salinity distribution within the tillage layer, a small volume with multiple drip-irrigation methods was employed in this study to maintain the salt content in the tillage layer at approximately 0.7%. Subsequently, we compared the survival rate, fresh weight, dry weight, and overall field performance of these triticale resources. As a result, nine resources demonstrating excellent comprehensive performance were selected: Jisi 6, HS518, HS476, Jisi 4, HS520, HS541, HS447, HS530, and HS139. These selected triticale resources exhibit strong salt tolerance and high biomass production;therefore, they are deemed suitable for further cultivation.
