| 摘 要： | 对紫花苜蓿种子田进行了不同灌溉处理,测定了不同处理的种子产量、株高、千粒重、花序数/生殖枝、豆荚数/花序、籽粒数/豆荚等产量构成因素及发芽势、发芽率等指标.结果表明,在孕蕾-初花期灌水可形成较高苜蓿种子产量(721.8 kg·hm-2),较对照提高15.6％.不同灌水处理在株高、千粒重、结荚花序数/生殖枝、荚果数/花序...

| Abstract: | The experimental study of different irrigation treatments on the factors of the alfalfa seed yield.The different irrigation treatments on processing of seed yield,plant height,thousands of grain number/reproductive branches,pod/inflorescence,grain number/pods yield components,germination rate and germination energy etc.The results showed that alfalfa seed yield was more Irrigation during Flower Initiation Stage(721.8 kg·hm-2),and increase 15.6% than tjat pf CK,there were obvious differences in different irrigation treatments on plant height,thousands of grain number/reproductive branches,pod/inflorescence,number/reproductive branches,pod/inflorescence were more positively correlated to and alfalfa seed yield.With correlation coefficients of 0.789,0.760,respectively. |
