硅元素对甘蔗增产和增糖作用机理的研究 Ⅳ.硅元素对甘蔗中营养元素分布的影响

Study on Behaviour Mechanism of Increasing Production and Sugar of Cane Caused by Silicon Ⅳ. Effect of Silicon on Distribution of Nutritive Elements in Sugarcane

硅元素对甘蔗中营养元素分布的影响,研究结果表明,硅元素促进氮、磷、钾等11种营养元素从甘蔗的成熟部分向生长部分的转移和富集,提高了营养元素在蔗茎生长部分和蔗叶中的含量,从而促进了甘蔗的生长、蔗糖的合成和积累。

Effect of silicon on distribution of nutritive elements in sugarcane was researched. It is shown that silicon encourages metastasis and concentration of N, P, K, etc. eleven nutritive elements from mature parts to growth fraction, and increasing content of nutritive element in growth fraction and leaf, thus encourages growth of sugarcane , synthesis and cumuration of sugar.
