【摘要】 为了研究施用纳米肥料399植物生长剂后小麦籽粒微结构和营养品质的变化,通过扫描电子显微镜(SEM)观察比较了施用和未施用399植物生长剂的小麦籽粒的外部形貌和截面特征.通过观察发现,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.对小麦蛋白质、脂肪、粗纤维和重金属的质量分数进行了检测分析.结果表明,施用399植物生长剂的小麦蛋白质质量分数提高了8%以上,粗脂肪质量分数提高了5%以上;粗纤维、铅的质量分数与399植物生长剂的施用没有正相关性.更多还原

【Abstract】 Varies of microstructure and nutritional quality of wheat seeds after application of nano fertilizer 399 are studied in this paper.The exterior topography and profiles features of wheat seeds are observed and compared between those applied with the nano fertilizer 399 and those not applied with the nano fertilizer 399 by Scanning Electron Microscope(SEM).From the observation of the wheat seeds with SEM,it is found that the 399 has the functions of promoting all of the growth of the epidermal cells,the aleurone layer and the albumen.In addition,the wheat applied with and those not applied with the 399 are detected in four aspects respectively,that is,the quality percentages of protein,fat,coarse fibres and heavy metal Pb.The results indicate that the wheat applied with the nano fertilizer 399 has significantly increased contents of both protein and fat.The contents of coarse fibres and Pb has no positive correlation with the application of the 399 nano fertilizer.更多还原
