摘要
通过对紫花苜蓿施硅的研究表明,硅可提高紫花苜蓿种子的发芽率和发芽势;硅对发芽幼苗具有明显的促进作用,却对种子胚根的发育有抑制作用;低浓度的硅可增加种子幼苗的单株鲜重;施硅对生长高度有促进作用,可使紫花苜蓿的生育期提前3～6 d.
Effect of Si fertilizer on early alfalfa growth was studied. The results showed that Si fertilizer increases seeds vigor of germination and germination capacity, and promotes seedling development, but inhibits seed radicel development; low concentration of Si fertilizer increases fresh weight of single Alfalfa of seedling; Si fertilizer shortens growth duration 3~6 days.
