肥料增效剂聚天冬氨酸的应用效果研究

Study on Poly as Fertilizer Synergist

以L -天冬氨酸为原料 ,热缩合成聚天冬氨酸酐 ,水解得到聚天冬氨酸。采用凝胶色谱法 (GPC)测定了聚天冬氨酸的分子量 ,用核磁共振 (NMR)对其进行了表征。稻谷生长试验初步证实 。

Poly (anhydroaspartic acid) was prepared by thermal condensation of L-aspartic acid, which can be hydrolyzed to poly. The weight-average molecular weights (Mw) were measured with GPC. Poly was characterized with the method of NMR. It was demonstrated that poly was a good fertilizer synergist.
