Abstract—

A preparation based on iron, zinc, copper, and molybdenum nanoparticles (NPs) in a polymer film formed from a mixture of Na-carboxymethylcellulose and polyethylene glycol-400 was developed for presowing pretreatment of potato tubers. Based on laboratory tests, the optimal concentrations and ratio of Fe : Zn : Cu : Mo nanoparticles were determined as 10^–6 : 10^–2 : 10^–8 : 10^–8 (%). Field tests in the integrated system of potato protection showed that the presowing treatment of potato tubers with nanoparticles Fe : Zn : Cu : Mo in the polymer film reduced the prevalence and degree of development of Alternaria blight (2.2 and 2.4 times) and late blight of potato (3.4 and 4.2 times) during the growing season and led to an increase in yield of marketable products by 11.7% compared to the control.

含金属纳米颗粒膜包衣的马铃薯块茎预播处理对病理和产量的影响

摘要—

开发了一种基于铁，锌，铜和钼纳米颗粒（NPs）的制剂，该聚合物膜由Na-羧甲基纤维素和聚乙二醇400的混合物形成，用于马铃薯块茎的预播预处理。根据实验室测试，确定Fe，Zn，Cu，Mo纳米粒子的最佳浓度和比例为10 ^–6：10 ^–2：10 ^–8：10 ^–8（％）。在马铃薯保护综合系统中的田间试验表明，用聚合物膜中的纳米颗粒Fe：Zn：Cu：Mo对马铃薯块茎进行预播处理，可以降低马铃薯疫病的发病率和发展程度（2.2和2.4倍）和马铃薯晚疫病的发生率。马铃薯在生长季节的产量（分别是马铃薯的3.4倍和4.2倍），导致可销售产品的产量与对照相比增加了11.7％。
