宁夏引黄灌区27个紫花苜蓿品种的生产性能和萌发过程耐盐性比较
Comparison of Production Performance and Salt Tolerance during Germination Process of 27 Medicago sativa L.Varieties in Yellow River Irrigation Area of Ningxia
摘要
Abstract
Medicago sativa is a high-yielding and high-quality perennial leguminous forage grass with certain salt tolerance,but there are significant differences in salt tolerance among different varieties.To improve the utilization efficiency of saline-alkali land and provide high-quality protein feed,the production performance and salt tolerance at the germination stage of 27 Medicago sativa varieties in the Yellow River irrigation area of Ningxia were evaluated.The NaCl stress test showed that'Guochanmuxu 2'was more sensitive to salt,while'Saiwo 5','Qianjing'and'Zhongmu No.3'showed strong salt tolerance.These varieties outperformed other varieties in relative germination rate,relative germination energy and germination speed.'Qianjing','SK3010','Daoqi','Weishen'and'Zhongmu No.4'showed better production performance in the irrigation area.Based on the analysis of yield and germination characteristics,'Qianjing'and'Zhongmu No.3'were preliminarily selected as suitable salt-tolerant Medicago sativa varieties for planting in the Yellow River irrigation area of Ningxia.This study provides a scientific basis for the screening and improvement of salt-tolerant Medicago sativa varieties in the Yellow River irrigation area of Ningxia.关键词
