摘  要:
硅是一种在植物生命活动中起着重要生理作用的元素 ,由于多数园艺植物中硅含量极低 ,因而测定其含量非常困难 .在本研究中 ,将三种现存方法改进后应用于园艺作物硅含量的分析 .结果发现 ,利用高压消煮法虽然具有不使用危险化学品 HF的优点 ,但对于含硅量较低的园艺作物 ,例如苹果 ,梨等 ,其回收率低 ,测定结果不稳定 .利用 HCl- HF混合液振荡过夜抽提其中的硅后 ,再利用 ICAP分析 ,可以明显提高 Si分析的敏感性和准确性 ,故适用于各种园艺作物硅的测定

摘  要:
Si plays an important role in plant growth and development. In the past, determination of silicate content in horticultural materials was laborious and/or difficult. In the present study, three methods to analyze Si in horticultural crops including apple, peach, melon, and bluegrass were compared. Among those methods, digestion of material with HCl HF solution by shaking overnight followed by inductively coupled agron plasma (ICAP) procedure was proved to be sensitive, rapid and accurate for reducing potential errors. The autoclave induced digestion appeared to be suitable to the horticultural crops with high Si content, but not to those with low Si content such as apple and peach.
