| 摘 要： | 以公农1号紫花苜蓿为试验材料,研究不同田间灌水量处理对当年播种紫花苜蓿各农艺性状的影响。结果表明:灌水对紫花苜蓿产量与生长高度等农艺性状有显著影响,产草量随着灌水量的增加达高峰值后变为负增长;灌水量与农艺性状之间的灰色关联度分析表明,适宜的灌水会提高紫花苜蓿的叶量与产量。

| Abstract: | With the cultivar Gongnong 1 as experiment material,the effects of different irrigation amount on the agronomic characters of alfalfa(Medicago sativa L.) in the seeding year were studied.The results showed that irrigation significantly influenced the alfalfa yield and the agronomic characters such as plant height.With the increase of irrigation amount,the grass yield increased firstly and then decreased.The grey correlation degree analysis showed that the suitable irrigation could increase the leaf quantity and the grass yield. |
