| 摘 要： | 在干旱、半干旱地区生产苜蓿种子时,不同灌水处理对苜蓿的植株高度、叶片相对含水量、生殖分配及种子产量均有不同程度的影响。其中,灌水时期的影响大于灌水总量的影响。苜蓿分枝期是营养物质快速积累时期,应控制灌水;苜蓿在现蕾至初花期灌水可得到较高生殖分配率和种子产量,并显著高于其他时期灌水的处理;在结荚期适当的补充水分,有利于苜蓿籽粒饱满。

| Abstract: | When alfalfa seeds were produced in arid and semi-arid area,the different effects of different irrigation freatment were produced on height of plant,the relative water content of blade,reproduction allocation(RA) and the seed yield of plant,among which the effect of irrigation stage was more important than the total amount of it.The nutrition matter accumulation was fast during branching stage, so to control irrigation was necessary;The higher reproduction allocation and seed yield could be obtained during irrigation of budding initial flowering stage,which was remarkablly higher than the irrigation treatment of other stages.The proper complement of water at podding stage was benefit for plumping seeds of alfalfa. |
