| 摘 要： | 施硅对紫花苜蓿(Medicago sativa L.) 叶鲜重、叶干重、单株花序重具有明显增加的作用,可使紫花苜蓿使鲜草产量增加 16.4 %,干草产量增加 24.1 %,但对紫花苜蓿分枝后期茎质量的积累没有作用,成熟期施硅对紫花苜蓿茎干重和单株根量具有显著的增加作用。盆栽试验表明,硅对紫花苜蓿当年种子产量的影响作用不明显,但对当年的千粒重有影响,用硅处理过的种子千粒重比对照提高 29 %以上。 |
| 关 键 词： | 紫花苜蓿 硅肥 产草量 千粒重 |

| Abstract: | Silicon fertilizer raised leaf fresh weight, leaf dry weight and inflorescence weight. The fresh and dry grass productions were increased by 16.4 %and 24.1 %, respectively; however, stem weight had no effect. When used during mature stage, Silicon increased significantly the stem dry weight and the root number. A pot trial showed that Si had not effected on seed yield of first year; however, significantly increased thousand-seed weight by 29 %. |
