【摘要】 通过扫描电子显微镜(SEM)和透射电镜(TEM)对纳米肥料 399 植物生长剂样品进行了成份分析和粒径大小的观测。样品的粒径非常均匀,约在 10～20nm 之间,如此细小且均匀的颗粒有利于植物的吸收,有效地改善了普通化肥吸收效率低的问题。样品所含元素成份大致为:C、N、O、F、Na、Mg、Al、Si、P、S、Cl、K、Ca、Ti、Cr、Fe、Cu、Sr 和 I,其中 C、N、O、Mg、P、S、K、Ca 是植物必需的且是大量需要的营养元素。主要来自于有机物和无机氧化物的 C 和 O 的原子比例非常高,达到 80%～90%,N、Mg、Si、P、K、Ca 的含量也相对较高。而Na、Si、Cl、Fe、Cu 也是植物有益的营养元素。本文还利用 SEM 观察比较了施用和未施用 399 植物生长剂小麦籽粒的外部形貌和切面特征。观察发现,399 植物生长剂对表皮细胞、糊粉层及胚乳的生长都有促进作用。按照中华人民共和国卫生部中国国家标准化管理委员会于 2003 年 11 月发布的食品安全国家标准,对施用和未施用 399植物生长剂的小麦进行了蛋白质、脂肪、粗纤维和重金属含量的检测。检测表明,施用 399 植物生长剂的小麦蛋白质和粗脂肪含量都提高约一个百分点;粗纤维与铅含量与 399 植物生长剂的施用没有正相关性。更多还原

【Abstract】 Composition analyses and particulate measurements for a nano fertilizer, 399 plant growth regulator, were conducted with TEM and SEM, and the profiles and section features of wheat seeds were observed and compared between those applied with the 399 plant growth regulator and those not applied with the same. The 399 plant growth regulator (hereinafter referred to as "the 399 regulator") is a nano fertilizer with very uniform particulate sizes ranging between 10nm and 20nm. The 399 regulator generally comprises compositions of C, N, O, F, Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Fe, Cu, Sr and I, in which C and O mainly from organic substances and inorganic oxides have a very high atom ratio up to 80-90%, and N, Mg, Si, P, K and Ca also have a high content. Pursuant to the National Standard for Food Safety issued in November, 2003 by the National Standardization Governing Committee of China, the Health Department of P.R.China, the wheats applied with the 399 regulator and those not applied with the same were detected in four aspects, the contents of protein, fat, coarse fibres and heavy metals.更多还原
